+v1.05
+      -- Added Technote #6 which covers the current PK compliance.  
+      -- Fixed buffer overflow in OAEP decoder
+      -- Added CHOICE to the list of ASN.1 types
+      -- Added UTCTIME to the list of ASN.1 types
+      -- Added MUTEX locks around descriptor table functions [but not on the functions that are dependent on them]
+         All functions call *_is_valid() before using a descriptor index which means the respective table must be unlocked before 
+         it can be accessed.  However, during the operation [e.g. CCM] if the descriptor has been altered the results will be 
+         undefined.  
+      -- Minor updates to the manual to reflect recent changes
+      -- Added a catch to for an error that should never come up in rsa_exptmod().  Just being thorough.
+
+June 15th, 2005
+v1.04
+      -- Fixed off by one [bit] error in dsa_make_key() it was too high by one bit [not a security problem just inconsistent]
+      -- ECC-224 curve was wrong [it was an ok curve just not NIST, so no security flaw just interoperability].
+      -- Removed point compression since it slows down ECC ops to save a measly couple bytes.
+         This makes the ecc export format incompatible with 1.03 [it shouldn't change in the future]
+      -- Removed ECC-160 from timing and added the other curves
+
+June 9th, 2005
+v1.03
+      -- Users may want to note that on a P4/GCC3.4 platform "-fno-regmove" greatly accelerates the ciphers/hashes.
+      --------------------------------------------------------------------------------------------------------------
+      -- Made it install the testing library in the icc/static makefiles
+      -- Found bug in ccm_memory.c which would fail to compile when LTC_CLEAN_STACK was enabled
+      -- Simon Johnson proposed I do a fully automated test suite.  Hence "testme.sh" was born
+      -- Added LTC_NO_TEST which forces test vectors off (regardless of what tomcrypt_custom.h has)
+      -- Added LTC_NO_TABLES which disables large tables (where possible, regardless of what tomcrypt_custom.h has)
+      -- New test script found a bug in twofish.c when TABLES was disabled.  Yeah testing!
+      -- Added a LTC_FAST specific test to the testing software.
+      -- Updated test driver to actually halt on errors and just print them out (useful for say... automated testing...)
+      -- Added bounds checking to Pelican MAC
+      -- Added BIT and OCTET STRING to the ASN.1 side of things.  
+      -- Pekka Riikonen pointed out that my ctr_start() function should accept the counter mode. 
+      -- Cleaned up warnings in testprof
+      -- Removed redundant mu and point mapping in ecc_verify_hash() so it should be a bit faster now
+      -- Pekka pointed out that the AES key structure was using 32 bytes more than it ought to.
+      -- Added quick defines to remove entire classes of algorithms.  This makes it easier if you want to build with just 
+         one algorithm (say AES or SHA-256).  Defines are LTC_NO_CIPHERS, LTC_NO_MODES, LTC_NO_HASHES, LTC_NO_MACS,
+         LTC_NO_PRNGS, LTC_NO_PK, LTC_NO_PKCS
+      -- As part of the move for ECC to X9.62 I've changed the signature algorithm to EC DSA.  No API changes.
+      -- Pekka helped me clean up the PKCS #1 v2.1 [OAEP/PSS] code
+      -- Wrote new DER SEQUENCE coder/decoder
+      -- RSA, DSA and ECDSA now use the DER SEQUENCE code (saves a lot of code!)
+      -- DSA output is now a DER SEQUENCE (so not compatible with previous releases).  
+      -- Added Technote #5 which shows how to build LTC on an AMD64 to have a variety of algorithms in only ~80KB of code.
+      -- Changed temp variable in LOAD/STORE macros to "ulong32" for 32-bit ops.  Makes it safer on Big endian platforms
+      -- Added INSTALL_GROUP and INSTALL_USER which you can specify on the build to override the default USER/GROUP the library 
+         is to be installed as
+      -- Removed "testprof" from the default build.  
+      -- Added IA5, NULL and Object Identifier to the list of ASN.1 DER supported types
+      -- The "no_oops" target (part of zipup) now scans for non-cvs files.  This helps prevent temp/scratch files from appearing in releases ;-)
+      -- Added DERs for missing hashes, but just the OID not the PKCS #1 v1.5 additions. 
+      -- Removed PKCS #1 v1.5 from the tree since it's taking up space and you ought to use v2.1 anyways
+      -- Kevin Kenny pointed out a few stray // comments
+      -- INTEGER code properly supports negatives and zero padding [Pekka!]
+      -- Sorted asn1/der/ directory ... less of a mess now ;-)
+      -- Added PRINTABLE STRING type
+      -- Removed ECC-160 as it wasn't a standard curve
+      -- Made ecc_shared_secret() ANSI X9.63 compliant
+      -- Changed "printf" to "fprintf(stderr, " in the testbench... ;-)
+      -- Optimized the GCM table creation.  On 1KB packets [with key switching] the new GCM is 12.7x faster than before.
+      -- Changed OID representation for hashes to be just a list of unsigned longs (so you can compare against them nicely after decoding a sequence)
+      -- ECC code now uses Montgomery reduction ... it's even faster [ECC-256 make key down from 37.4M to 4.6M cycles on an Athlon64]
+      -- Added SHORT_INTEGER so users can easily store DER encoded INTEGER types without using the bignum math library
+      -- Fixed OMAC code so that with LTC_FAST it doesn't require that LTC_FAST_TYPE divides 16 [it has to divide the block size instead]
+      -- ECC key export is now a simple [and documented] SEQUENCE, the "encrypt_key" also uses a new SEQUENCE format.
+      -- Thanks goes to the following testers
+            Michael Brown             - Solaris 10/uSPARCII
+            Richard Outerbridge       - MacOS
+            Martin Carpenter          - Solaris 8/uSPARCII [Thanks for cleaning up the scripts]
+            Greg Rose                 -  ... SunOS 5.8/SPARC [... what's with the SPARCS?]
+            Matt Johnston             - MacOS X  [Thanks for pointing out GCC 4 problems with -Os]
+
+April 19th, 2005
+v1.02
+      -- Added LTC_TEST support to gcm_test()
+      -- "pt/ct" can now be NULL in gcm_process() if you are processing zero bytes
+      -- Optimized GCM by removing the "double copy" handling of the plaintext/aad
+      -- Richard Outerbridge pointed out that x86_prof won't build on MACOS and that the manual 
+         erroneously refers to "mycrypt" all over the place.  Fixed.
+
+April 17th, 2005
+v1.01
+       ** Secure Science Corporation has supported this release cycle by sponsoring the development time taken.  Their 
+          continuing support of this project has helped me maintain a steady pace in order to keep LibTomCrypt up to date,
+          stable and more efficient.
+       -----------------------------------------------------------------------------------------------------
+       -- Updated base64_decode.c so if there are more than 3 '=' signs it would stop parsing
+       -- Merged in latest mpi that fixed a few bugs here and there
+       -- Updated OAEP encoder/decoder to catch when the hash output is too large
+          Cleaned up PSS code too
+       -- Andy Bontoft fixed a bug in my demos/tests/makefile.msvc ... seems "dsa_test.c" isn't an object
+          afterall.  Thanks.
+       -- Made invalid ECC key sizes (configuration) not hard fault the program (it returns an error code now)
+       -- SAFER has been re-enabled after I was pointed to http://www.ciphersbyritter.com/NEWS2/95032301.HTM
+          [Mark Kotiaho]
+       -- Added CCM mode to the encauth list (now has EAX, OCB and CCM, c'est un treo magnifique!)
+       -- Added missing ASN.1 header to the RSA keys ... oops... now the rsa_export/import are FULLY compatible
+          with other libs like OpenSSL (comment:  Test vectors would go a long way RSA...)
+       -- Manually merged in fix to the prime_random_ex() LTM function that ensures the 2nd MSB is set properly.  Now
+          When you say "I want a 1024/8 byte RSA key" the MSB bit of the modulus is set as expected.  Note I generally 
+          don't view this as a "huge issue" but it's just one less nit to worry about. [Bryan Klisch]
+       -- A new CVS has been setup on my Athlon64 box... if you want developer access send me an email (and at this point the email would have to be awesome).
+       -- Updated API for ECB and CBC shell code.  Now can process N whole blocks in one call (like $DEITY intended)
+       -- Introduced a new "hardware accel" framework that can be used to speed up cipher ECB, CBC and CTR mode
+          calls.  Later on dependent code (e.g. OMAC, CCM) will be re-written to use the generic cbc/ctr functions.  But now
+          if you [say] call ctr_encrypt() with a cipher descriptor that has hardware CTR it will automatically
+          be used (e.g. no code rewrites)
+       -- Now ships with 20% more love.
+       -- x86_prof now uses ECB shell code (hint: accelerators) and outputs cycles per BLOCK not byte.  This will make it a bit 
+          easier to compare hardware vs. software cipher implementations.  It also emits timings for CBC and CTR modes
+       -- [Peter LaDow] fixed a typo w.r.t. XREALLOC macro (spelling counts kids!)
+       -- Fixed bug with __x86_64__ where ROL64/ROR64 with LTC_NO_ROLC would be the 32-bit versions instead...
+       -- Shipping with preliminary GCM code (disabled).  It's buggy (stack overflow hidden somewhere).  If anyone can spot it let me know.
+       -- Added Pelican MAC [it's an AES based fast MAC] to the list of supported MACs
+       -- Added LTC_FAST [and you can disable by defining LTC_NO_FAST] so that CBC and CTR mode XOR whole words [e.g. 32 or 64 bits] at a time
+          instead of one byte.  On my AMD64 this reduced the overhead for AES-128-CBC from 4.56 cycles/byte to around 1 cycle/byte.  This requires
+          that you either allow unaligned read/writes [e.g. x86_32/x86_64] or align all your data.  It won't go out of it's way to ensure 
+          aligned access.  Only enabled for x86_* platforms by default since they allow unaligned read/writes.
+       -- Added LTC_FAST support to PMAC (drops the cycle/byte by about 9 cycles on my AMD64) [note: I later rewrote this prior to release]
+       -- Updated "profiled" target to work with the new directory layout
+       -- Added [demo only] optimized RC5-CTR code to x86_prof demo to show off how to make an accelerator
+          [This has been removed prior to release... It may re-appear later]
+       -- Added CCM acelerator callbacks to the list [now supports ECB, CTR, CBC and now CCM].
+       -- Added chapter to manual about accelerators (you know you want it)
+       -- Added "bswap" optimizations to x86 LOAD/STORE with big endian.  Can be disabled by defining LTC_NO_BSWAP
+       -- LTC_NO_ASM is now the official "disable all non-portable stuff" macro.  When defined it will make the code endian-neutral,
+          disable any form of ASM and disable LTC_FAST load/stores.  Essentially build the library with this defined if you're having
+          trouble building the library (old GCCs for instance dislike the ROLc macro)
+       -- Added tomcrypt_mac.h and moved MAC/encMAC functions from tomcrypt_hash.h into it
+       -- Added "done" function to ciphers and the five chaining modes [and things like omac/pmac/etc]
+       -- Changed install group to "wheel" from "root".
+       -- Replaced // comments with /**/ so it will build on older UNIX-like platforms
+       -- x86_prof builds and runs with IntelCC fine now 
+       -- Added "stest" build to intel CC to test static linked from within the dir (so you don't have to install to test)
+       -- Moved testing/benchmark into testprof directory and build it as part of the build.  Now you can link against libtomcrypt_prof.a to get 
+          testing info (hint: hardware developers ;-) )
+       -- Added CCM to tv_gen 
+       -- Added demos to MSVC makefile
+       -- Removed -funroll-all-loops from GCC makefile and replaced with -funroll-loops which is a bit more sane (P4 ain't got much cache for the IDATA)
+       -- Fixed GCM prior to release and re-enabled it.  It has not been optimized but it does conform when compiled with optimizations.
+       -- I've since optimized GCM and CCM.  They're close in speed but GCM is more flexible imho (though EAX is more flexible than both)
+       -- For kicks I optimized the ECC code to use projective points.  Gets between 3.21x (Prescott P4) to 4.53x (AMD64) times faster than before at 160-bit keys and the
+          speedup grows as the keysize grows.  Basically removing most practical reasons to "not use the ECC code".  Enjoy.
+       -- Added LTC_FAST support to OMAC/PMAC and doubled it's speed on my amd64 [faster on the P4 too I guess]
+       -- Added GCM to tv_gen
+       -- Removed "makefile.cygwin_dll" as it's not really used by anyone and not worth the effort (hell I hardly maintain the MSVC makefiles ...)
+       -- Updated a few files in the "misc" directory to have correct @file comments for doxygen
+       -- Removed "profile" target since it was slower anyways (go figure...)
+
+December 31st, 2004
+v1.00  
+       -- Added "r,s == 0" check to dsa_verify_hash()
+       -- Added "multi block" helpers for hash, hmac, pmac and omac routines so you can process multiple non-adjacent
+          blocks of data with one call (added demos/multi.c to make sure they work)
+          -- Note these are not documented but they do have doxygen comments inside them
+          -- Also I don't use them in other functions (like pkcs_5_2()) because I didn't have the time.  Job for the new LTC maintainer ;-)
+       -- Added tweaked Anubis test vectors and made it default (undefined ANUBIS_TWEAK to get original Anubis)
+       -- Merged in fix for mp_prime_random_ex() to deal with MSB and LSB "bugs"
+       -- Removed tim_exptmod() completely, updated several RSA functions (notably v15 and the decrypt/verify) so they 
+          don't require a prng now
+       -- This release brought to you by the fine tunes of Macy Gray.  We miss you.
+
+December 23rd, 2004
+v1.00rc1
+       -- Renamed "mycrypt_*" to "tomcrypt_*" to be more specific and professional
+          Now just include "tomcrypt.h" instead of "mycrypt.h" to get LTC ;-)
+       -- Cleaned up makefiles to ensure all headers are correctly installed
+       -- Added "rotate by constant" macros for portable, x86-32 and x86-64
+          You can disable this new code with LTC_NO_ROLC which is useful for older GCCs
+       -- Cleaned up detection of x86-64 so it works for ROL/ROR macros
+       -- Fixed rsa_import() so that it would detect multi-prime RSA keys and error appropriately
+       -- Sorted the source files by category and updated the makefiles appropriately
+       -- Added LTC_DER define so you can trim out DER code if not required
+       -- Fixed up RSA's decrypt functions changing "res" to "stat" to be more in sync
+          with the signature variables nomenclature. (no code change just renamed the arguments)
+       -- Removed all labels starting with __ and replaced with LBL_ to avoid namespace conflicts (Randy Howard)
+       -- Merged in LTM fix to mp_prime_random_ex() which zap'ed the most significant byte if the bit size
+          requested was a multiple of eight.
+       -- Made RSA_TIMING off by default as it's not terribly useful [and likely to be deprecated]
+       -- Renamed SMALL_CODE, CLEAN_STACK and NO_FILE to have a LTC_ prefix to avoid namespace collisions
+          with other programs.  e.g. SMALL_CODE => LTC_SMALL_CODE
+       -- Zed Shaw pointed out that on certain systems installing libs as "root" isn't possible as the super-user
+          is not root.  Now the makefiles allow this to be changed easily.
+       -- Renamed "struct _*_descriptor" to "struct ltc_*_descriptor" to avoid using a leading _
+          Also renamed _ARGCHK to LTC_ARGCHK
+       -- Zed Shaw pointed out that I still defined the prng structs in tomcrypt_prng.h even if they 
+          weren't defined.  This made undef'ing FORTUNA break the build.
+       -- Added LTC_NO_ASM to disable inline asm macros [ROL/ROR/etc]
+       -- Changed RSA decrypt functions to change the output length variable name from "keylen" to "outlen" to make 
+          it more consistent.
+       -- Added the 64-bit Khazad block cipher [NESSIE]
+       -- Added the 128-bit Anubis block cipher [with key support for 128...320 bit keys] [NESSIE]
+       -- Changes to several MAC functions to rename input arguments to more sensible names
+       -- Removed FAST_PK support from dh_sys.c
+       -- Declared deskey() from des.c as static instead of a global
+       -- Added pretty much all practical GCC warning tests to the GCC [related] makefiles.  These additional
+          warnings can easily be disabled for those with older copies of GCC [or even non GNU cc's]
+       -- Added doxygen @ tags to the code...  phew that was a hell of a lot of [repetitive] work
+       -- Also added pre-configured Doxygen script.
+       -- Cleaned up quite a few functions [ciphers, pk, etc] to make the parameters naming style consistent
+          E.g. ciphers keys are called "skey" consistently now.  The input to PK encryption is called "in", etc.
+          These changes require no code changes on the behalf of developers fortunately
+       -- Started a SAFER+ optimizer [does encrypt only] which shaves a good 30 or so cycles/byte on my AMD64
+          at an expense of huge code.  It's in notes/etc/saferp_optimizer.c
+       -- DSA sign/verify now uses DER encoded output/inputs and no LTC style headers.  
+       -- Matt Johnston found a missing semi-colon in mp_exptmod().  Fix has been merged in.  
+
+October 29th, 2004
+v0.99  -- Merged in the latest version of LTM which includes all of the recent bug fixes
+       -- Deprecated LTMSSE and removed it (to be replaced with TFM later on)
+       -- Stefan Arentz pointed out that mp_s_rmap should be extern
+       -- Kristian Gjøsteen pointed out that there are typos in the 
+          "test" makefile and minor issues in Yarrow and Sober [just cosmetics really]
+       -- Matthew P. Cashdollar pointed out that "export" is a C++ keyword 
+          so changed the PRNG api to use "pexport" and "pimport"
+       -- Updated "hashsum" demo so it builds ;-)
+       -- Added automatic support for x86-64 (will configure for 64-bit little endian automagically)
+       -- Zhi Chen pointed out a bug in rsa_exptmod which would leak memory on error. 
+       -- Made hash functions "init" return an int.  slight change to API ;-(
+       -- Added "CHC" mode which turns any cipher into a hash the other LTC functions can use
+       -- Added CHC mode stuff to demos such as tv_gen and hashsum
+       -- Added "makefile.shared" which builds and installs shared/static object copies
+          of the library.
+       -- Added DER for bignum support 
+       -- RSA is now fully joy.  rsa_export/rsa_import use PKCS #1 encodings and should be 
+          compatible with other crypto libs that use the format.
+       -- Added support for x86-64 for the ROL/ROR macros 
+       -- Changed the DLL and SO makefiles to optimize for speed, commented SMALL_CODE in
+          mycrypt_custom.h and added -DSMALL_CODE to the default makefile
+       -- Updated primality testing code so it does a minimum of 5 tests [of Miller-Rabin]
+          (AFAIK not a security fix, just warm fuzzies)
+       -- Minor updates to the OMAC code (additional __ARGCHK and removed printf from omac_test... oops!)
+       -- Update build and configuration info which was really really really out of date.  (Chapter 14)
+       ++ Minor update, switch RSA to use the PKCS style CRT
+
+August 6th, 2004
+v0.98  -- Update to hmac_init to free all allocated memory on error
+       -- Update to PRNG API to fix import/export functions of Fortuna and Yarrow
+       -- Added test functions to PRNG api, RC4 now conforms ;-) [was a minor issue]
+       -- Added the SOBER-128 PRNG based off of code donated by Greg Rose.
+       -- Added Tech Note #4 [notes/tech0004.txt] 
+       -- Changed RC4 back [due to request].  It will now XOR the output so you can use it like 
+          a stream cipher easily.
+       -- Update Fortuna's export() to emit a hash of each pool.  This means that the accumulated 
+          entropy that was spread over all the pools isn't entirely lost when you export/import.
+       -- Zhi Chen suggested a comment for rsa_encrypt_key() to let users know [easily] that it was
+          PKCS #1 v2.0 padding.  (updated other rsa_* functions)
+       -- Cleaned up Noekeon to remove unrolling [wasn't required, was messy and actually slower with GCC/ICC]
+       -- Updated RC4 so that when you feed it >256 bytes of entropy it quietly ignores additional
+          bytes.  Also removed the % from the key setup to speed it up a bit.
+       -- Added cipher/hash/prng tests to x86_prof to help catch bugs while testing
+       -- Made the PRNG "done" return int, fixed sprng_done to not require prng* to be non-null
+       -- Spruced up mycrypt_custom.h to trap more errors and also help prevent LTMSSE from being defined
+          on non-i386 platforms by accident.
+       -- Added RSA/ECC/DH speed tests to x86_prof and cleaned it up to build with zero warnings
+       -- Changed Fortuna to count only entropy [not the 2 byte header] added to pool[0] into the 
+          reseed mechanism.  
+       -- Added "export_size" member to prng_descriptor tables so you can know in advance the size of 
+          the exported state for any given PRNG.  
+       -- Ported over patch on LTM 0.30 [not ready to release LTM 0.31] that fixes bug in mp_mul()/mp_div()
+          that used to result in negative zeroes when you multiplied zero by a negative integer.  
+          (patch due to "Wolfgang Ehrhardt" <Wolfgang.Ehrhardt@munich.netsurf.de>)
+       -- Fixed rsa_*decrypt_key() and rsa_*verify_hash() to default to invalid "stat" or "res".  This way
+          if any of the higher level functions fail [before you get to the padding] the result will be in
+          a known state].  Applied to both v2 and v1.5 padding helpers.
+       -- Added MACs to x86_prof
+       -- Fixed up "warnings" in x86_prof and tv_gen
+       -- Added a "profiled" target back [for GCC 3.4 and ICC v8].  Doesn't seem to help but might be worth
+          tinkering with.
+       -- Beefed up load/store test in demos/test
+
+       ++ New note, in order to use the optimized LOAD/STORE macros your platform
+          must support unaligned 32/64 bit load/stores.  The x86s support this
+          but some [ARM for instance] do not.  If your platform cannot perform
+          unaligned operations you must use the endian neutral code which is safe for 
+          any sort of platform.

+July 23rd, 2004
+v0.97b -- Added PKCS #1 v1.5 RSA encrypt/sign helpers (like rsa_sign_hash, etc...)
+       -- Added missing prng check to rsa_decrypt_key() [not critical as I don't use 
+          descriptors directly in that function]
+       -- Merged in LTM-SSE, define LTMSSE before you build and you will get SSE2 optimized math ;-)
+          (roughly 3x faster on a P4 Northwood).  By default it will compile as ISO C portable
+          code (when LTMSSE is undefined).
+       -- Fixed bug in ltc_tommath.h where I had the kara/toom cutoffs not marked as ``extern''
+          Thanks to "Stefan Arentz" <stefan at organicnetwork.net>
+       -- Steven Dake <scd@broked.org> and Richard Amacker <ramacker@yahoo.com> submitted patches to 
+          fix pkcs_5_2().  It now matches the output of another crypto library.  Whoops... hehehe
+       -- Updated PRNG api.  Added Fortuna PRNG to the list of supported PRNGs
+       -- Fixed up the descriptor tables since globals are automatically zero'ed on startup.
+       -- Changed RC4 to store it's output.  If you want to encrypt with RC4
+          you'll have to do the XOR yourself.
+       -- Fixed buffer overflows/overruns in the HMAC code.  
+
+       ++ API change for the PRNGs there now is a done() function per PRNG.  You
+          should call it when you are done with a prng state.  So far it's
+          not absolutely required (won't cause problems) but is a good idea to
+          start.  
+
+
+June 23rd, 2004
+v0.97a ++ Fixed several potentially crippling bugs... [read on]
+       -- Fixed bug in OAEP decoder that would incorrectly report 
+          buffer overflows. [Zhi Chen]
+       -- Fixed headers which had various C++ missing [extern "C"]'s
+       -- Added "extern" to sha384_desc descriptor which I removed by mistake
+       -- Fixed bugs in ENDIAN_BIG macros using the wrong byte order [Matt Johnston]
+       -- Updated tiger.c and des.c to not shadow "round" which is intrinsic on
+          some C compilers.
+       -- Updated demos/test/rsa_test.c to test the RSA functionality better
+       ++ This update has been tested with GCC [v3.3.3], ICC [v8] and MSVC [v6+SP6] 
+          all on a x86 P4  [GCC/ICC tested in Gentoo Linux, MSVC in WinXP]
+       ++ Outcome: The bug Zhi Chen pointed out has been fixed.  So have the bugs
+          that Matt Johnston found.  
+
+June 19th, 2004
+v0.97  -- Removed spurious unused files [arrg!]
+       -- Patched buffer overflow in tim_exptmod()
+       -- Fixed buffer overrun bug in pkcs_1_v15_es_decode()
+       -- Reduced stack usage in PKCS #1 v2.0 padding functions (by several KBs)
+       -- Removed useless extern's that were an artifact from the project start... ;-)
+       -- Replaced memcpy/memset with XMEMCPY and XMEMSET for greater flexibility
+       -- fixed bugs in hmac_done()/hmac_init()/[various others()] where I didn't trap errors 
+       -- Reduced stack usage in OMAC/PMAC/HMAC/EAX/OCB/PKCS#5 by mallocing any significant sized
+          arrays (e.g. > 100 bytes or so).  Only in non-critical functions (e.g. eax_init())
+       -- "Zhi Chen" <zhi@massiveincorporated.com> pointed out that rsa_decrypt_key() requires
+          an incorrect output size (too large).  Fixed.
+       -- Added a "pretty" target to the GCC makefile.  Requires PERL.  It is NEAT!
+       -- Minor updates to ch1 of the manual.
+       -- Cleaned up the indentation and added comments to rsa_make_key(), rsa_exptmod() and 
+          rsa_verify_hash()
+       -- Updated makefile.icc so the "install" target would work ;-)
+       -- Removed demos/test.c [deprecated from demos/test/test.c]
+       -- Changed MAXBLOCKSIZE from 128 to 64 to reflect the true size...
+
+May 30th, 2004
+v0.96  -- Removed GF and Keyring code
+       -- Extended OAEP decoder to distinguish better [and use a more uniform API]
+       -- Changed PSS/OAEP API slightly to be more consistent with other PK functions (order of arguments)
+       -- rsa_exptmod() now pads with leading zeroes as per I2OSP.
+       -- added error checking to yarrow code
+       --  pointed out that tommath.h from this distro will overwrite tommath.h
+          from libtommath.  I changed this to ltc_tommath.h to avoid any such problems.
+       -- Fixed bug in PSS encoder/decoder that didn't handle the MSB properly
+       -- refactored AES, now sports an "encrypt only" descriptor which uses half as much code space.
+       -- modded Yarrow to try and use refactored AES code and added WHIRLPOOL support (d'oh) ;-)
+       -- updated ECB, OCB and CBC decrypt functions to detect when "encrypt only" descriptor is used.
+       -- replaced old RSA code with new code that uses PKCS #1 v2.0 padding
+       -- replaced old test harness with new over-engineer'ed one in /demos/test/
+       -- updated cbc/cfb/ofb/ctr code with setiv/getiv functions to change/read the IV without re-keying.
+       -- Added PKCS #1 v1.5 RSA encryption and signature padding routines
+       -- Added DER OID's to most hash descriptors (as many as I could find) 
+       -- modded rsa_exptmod() to use timing-resilient tim_exptmod() when doing private key operations 
+          added #define RSA_TIMING which can turn on/off this feature.
+       -- No more config.pl so please just read mycrypt_custom.h for build-time tweaks
+       -- Small update to rand_prime()
+       -- Updated sha1, md5 and sha256 so they are smaller when SMALL_CODE is defined.  If you want speed though,
+          you're going to have to undefine SMALL_CODE ;-)
+       -- Worked over AES so that it's even smaller now [in both modes].
+       
+May 12th, 2004
+v0.95  -- Optimized AES and WHIRLPOOL for SMALL_CODE by taking advantage of the fact
+          the transforms are circulant.  AES dropped 5KB and WHIRLPOOL dropped 13KB
+          using the default build options on the x86.
+       -- Updated eax so the eax_done() would clear the state [like hmac,pmac,ocb] when
+          CLEAN_STACK has been defined.
+       -- added LTC_TEST support to rmd160
+       -- updates to mycrypt_pk.h
+       -- updated rand_prime() to faciliate making RSA composites 
+       -- DSA/RSA now makes composites of the exact size desired.
+       -- Refactored quite a bit of the code, fewer functions per C file
+       -- cleaned up the makefiles to organize the objects logically
+       -- added ICC makefile along with "profiled" targets for both GNU and ICC compilers
+       -- Marked functions for removal before v1.00 see PLAN for more information
+       -- GCC 3.4.0 tested and seems to work
+       -- Added PKCS #5 support
+       -- Fixed typo in comment header of .C files  ;-)
+       -- Added PKCS #1 OAEP and PSS support.  
+       
+Feb 20th, 2004
+v0.94  -- removed unused variables from ocb.c and fixed it to match known test vectors.
+       -- Added PMAC support, minor changes to OMAC/EAX code [I think....]
+       -- Teamed up with Brian Gladman.  His code verifies against my vectors and my code
+          verifies against his test vectors.  Hazaa for co-operation!
+       -- Various small changes (added missing ARGCHKs and cleaned up indentation)
+       -- Optimization to base64, removed unused variable "c"
+       -- Added base64 gen to demos/tv_gen.c
+       -- Fix to demos/x86_prof.c to correctly identify the i386 architecture... weird...
+       -- Fixed up all of the PK code by adding missing error checking, removed "res" variables,
+          shrunk some stack variables, removed non-required stack variables and added proper
+          error conversion from MPI to LTC codes.  I also spotted a few "off by one" error
+          checking which could have been used to force the code to read past the end of
+          the buffer (in theory, haven't checked if it would work) by a few bytes.
+       -- Added checks to OUTPUT_BIGNUM so the *_export() functions cannot overflow the output and I 
+          also modded it so it stores in the output provided to the function (that is not on
+          the local stack) which saves memory and time.
+       -- Made SAFER default to disabled for now (plans are to cleanhouse write an implementation later)
+       -- Added the 512-bit one-way hash WHIRLPOOL which clocks in at 138 cycles per byte on my
+          Athlon XP [for comparison, SHA-512 clocks in at 77 cycles per byte].  This code uses the 
+          teams new sbox design (not the original NESSIE one).
+      
+
+Jan 25th, 2004
+v0.93  -- [note: deleted v0.93 changes by accident... recreating from memory...]
+       -- Fix to RC2 to not deference pointer before ARGCHK
+       -- Fix to NOEKEON to match published test vectors as well as cleaned up the code a bit
+       -- Optimized Twofish [down to 28 cycles/byte on my box] and Blowfish
+       -- Fix to OMAC to test cipher block size first [prevents wasting any time]
+       -- Added more OMAC test vectors
+       -- Added EAX Encrypt+Authenticate support
+       -- Fix to DSA to check return of a few LTM functions I forgot [mp_to_unsigned_bin]
+       -- Added common headers to all C files
+       -- CTR mode supports big and little [default] endian counters now.  
+       -- fix to find_cipher_any() so that it can handle a fragmented cipher_descriptor table.
+       -- added find_hash_any() akin to find_cipher_any().
+       -- Added EAX code to demos/tv_gen.c  Hazaa! 
+       -- Removed SONY defines and files from codebase.
+       -- Added OCB support [patents be damned] and to demos/tv_gen.c
+       -- Merge all of the INPUT/OUTPUT BIGNUM macros (less toc) into mycrypt_pk.h
+       -- Made appropriate changes to the debug string in crypt.c
+
+Dec 24th, 2003
+v0.92  -- Updated the config.pl script so the options have more details.
+       -- Updated demos/tv_gen to include RIPEMD hashes
+       -- Updated Twofish so when TWOFISH_ALL_TABLES is defined a pre-computed RS table
+          is included [speedup: slight, about 4k cycles on my Athlon].
+       -- Re-wrote the twofish large key generation [the four 8x32 key dependent tables].  Now about twice as fast.
+          With both optimizations [e.g. TWOFISH_ALL_TABLES defined] a 128-bit Twofish key can now be scheduled
+          in 26,000 cycles on my Athlon XP [as opposed to 49,000 before] when optimized for size.
+       -- config.pl has been updated so rmd128.o and rmd160.o are objects included in the build [oops]
+       -- Andrew Mann found a bug in rsa_exptmod() which wouldn't indicate if the wrong type of key was specified
+          (e.g. not PK_PRIVATE or PK_PUBLIC)
+       -- Fixed up demos/x86_prof so it sorts the output now :-)  
+       -- The project is now powered by radioactive rubber pants.
+       -- Fixed dh_encrypt_key() so if you pass it a hash with a smaller output than the input key it 
+          will return CRYPT_INVALID_HASH [to match what ecc_encrypt_key() will do]
+       -- Merge the store/encrypt key part of ecc_encrypt_key() as per dh_encrypt_key() [can you guess what I'm upto?]
+       -- Massive updates to the prime generation code.  I use the LTM random prime functions [and provide a nice 
+          interface between the LTC PRNG's and the LTM generic prng prototype].  I also use a variable number of tests
+          depending on the input size.  This nicely speeds up most prime generation/testing within the library.
+       -- Added SHA-224 to the list of hashes.
+       -- Made HMAC test vectors constant and static [takes ROM space instead of RAM]
+       -- This release was brought to you by the letter P which stands for Patent Infringement.
+       -- Added generic HASH_PROCESS macro to mycrypt_hash.h which simplifies the hash "process" functions
+          I also optimized the compression functions of all but MD2 to not perform input copies when avoidable.
+       -- Removed the division from the Blowfish setup function [dropped 3k cycles on my Athlon]
+       -- Added stack cleaning to rijndael, cast5 so now all ciphers have CLEAN_STACK code.  
+       -- Added Skipjack to the list of ciphers [made appropriate changes to demos/test.c, demos/tv_gen.c and 
+          demos/x86_prof.c]
+       -- Added mechanical testing to cipher test vector routines.  Now it encrypts 1000 times, then decrypts and
+          compares.  Any fault (e.g. bug in code, compiler) in the routines is likely to show through.  Doesn't
+          stress test the key gen though...
+       -- Matt Johnson found a bug in the blowfish.c  apparently I was out of my mind and put twofish defines in there 
+          The code now builds with any config.  Thanks.
+       -- Added OMAC1 Message Authentication Code support to the library.
+       -- Re-prototyped the hash "process" and "done" to prevent buffer overflows [which don't seem easy to exploit].  
+          Updated HMAC code to use them too.  Hazaa!
+       -- Fixed bug in ECC code which wouldn't do an _ARGCHK on stat in ecc_verify_hash().
+       -- Fixed [temp fix] bug in all PK where the OUTPUT_BIGNUM macros would not trap errors on the to_unsigned_bin 
+          conversion [now returns CRYPT_MEM, will fix it up better later]
+       -- Added DSA to the list of supported PK algorithms.  
+       -- Fixed up various ciphers to &255 the input key bytes where required [e.g. where used to index a table] to prevent
+          problems on platforms where CHAR_BIT != 8 
+       -- Merged in LibTomMath v0.28
+       -- Updated demos/x86_prof.c to use Yarrow during the key sched testing [was horribly slow on platforms with blockable
+          /dev/random]. 
+       -- Added OMAC/HMAC tests to demos/tv_gen and I now store the output of this in notes/ 
+       -- Fixed a bug in config.pl that wouldn't have TWOFISH_TABLES defined by default (too many commas on the line)
+       -- Fixed bug in hmac_done().  Apparently FIPS-198 [HMAC] specifies that the output can be truncated.  My code
+          would not support that (does now just like the new OMAC code).
+       -- Removed "hashsize" from hmac_state as it wasn't being used.
+       -- Made demos/test.c stop if OMAC or HMAC tests fail (instead of just printing a failed message and keep going).
+       -- Updated notes/tech0003.txt to take into account the existence of Skipjack [also I fixed a few typos].
+       -- Slight changes to Noekeon, with SMALL_CODE undefined it uses a fully unrolled version.  Dropped +10 cycles/byte
+          on my Athlon (35 cycles per byte or 410.4Mbit/sec at 1795Mhz)
+       -- Added _ARGCHK() calls to is_prime() for the two input pointers.
+
+Sept 25th, 2003
+v0.91  -- HMAC fix of 0.90 was incorrect for keys larger than the block size of the hash.
+       -- Added error CRYPT_FILE_NOTFOUND for the file [hmac/hash] routines.
+       -- Added RIPEMD hashes to the hashsum demo.
+       -- Added hashsum demo to MSVC makefile.
+       -- Added RMD160 to the x86_prof demo [oops]
+       -- Merged in LibTomMath-0.27 with a patch to mp_shrink() that will be in LibTomMath-0.28
+          Fixes another potential memory leak.
+
+Sept 7th, 2003
+v0.90  -- new ROL/ROR for x86 GCC
+       -- Jochen Katz submitted a patch to the makefile to prevent "make" from making the .a library
+          when not required.
+       == By default the KR code is not enabled [it's only a demo anyways!]
+       -- changed the "buf" in ecc_make_key from 4KB to 128 bytes [since the largest key is 65 bytes]
+       -- hmac_done() now requires you pass it the size of the destination buffer to prevent
+          buffer overflows.  (API CHANGE)
+       -- hmac/hash filebased routines now return CRYPT_NOP if NO_FILE is defined.
+       -- I've removed the primes from dh.c and replaced them with DR safe primes suitable for the default
+          configuration of LibTomMath.  Check out these comparisons on a 1.3Ghz Athlon XP, optimized for size,
+
+768-bit,     4 vs.  10
+1024-bit,    8 vs.  18
+1280-bit,   12 vs.  34

+2560-bit,   71 vs. 234
+3072-bit,  113 vs. 386
+4096-bit,  283 vs. 916
+
+          Times are all in milliseconds for key generation.  New primes times on the left.  This makes the code binary
+          incompatible with previous releases.  However, this addition is long overdue as LibTomMath has supported DR
+          reductions for quite some time.
+       -- Added RIPE-MD 128 and 160 to the list of supported hashes [10 in total].
+       -- The project has been released as public domain.  TDCAL no longer applies.
+
+July 15th, 2003
+v0.89  -- Fix a bug in bits.c which would prevent it from building with msvc
+       -- Merged in LibTomMath v0.24 [and I used the alloc/free macros this time!]
+       -- Removed the LTC version of next_prime() and replaced it with a call to the
+          mp_prime_next_prime() from LibTomMath
+       -- reverted bits.c to the 0.86 copy since the new one doesn't build in MSVC
+          or cygwin.
+
+Jul 10th, 2003
+v0.88  -- Sped up CAST5 key schedule for MSVC
+       -- added "ulong32" which allows people on 64-bit platforms to force the 32-bit tables in
+          ciphers like blowfish and AES to be 32-bits.  E.g. when unsigned long is 64-bits.
+       -- Optimized the SAFER-SK64, SAFER-SK128, SAFER+, RC5 and RC6 key schedule [big time!]
+       -- Optimized SHA-1 and SHA-256 quite a bit too.
+       -- Fixed up the makefile to use -fomit-frame-pointer more liberally
+       -- Added tv_gen program which makes test vectors for ciphers/hashes
+       -- Merged in LibTomMath v0.22
+       
+Jun 19th, 2003
+v0.87  -- Many MSVC optimizations to the code base
+       -- Improved the AES and Twofish key schedule [faster, more constant time]
+       -- Tons of optimizations here and there.  
+       
+Jun 15th, 2003
+v0.86  -- Fixed up AES to workaround MSVC optimizer bug
+       -- Merged in fresh LTM base [based on v0.20] so there are no warnings with MSVC
+       -- Wrote x86_prof which will time the hashes and ciphers downto cycles per byte.
+       -- Fixed up demos/encrypt to remove serpent_desc from the list
+       -- Re-enabled MSVC optimizations w00t w00t
+       -- Replaced "errno" with "err" in all functions that had it so it wouldn't clash
+          with the global "errno"
+       -- Removed a set of unused variables from certain functions
+       -- Removed {#line 0 "..."} stuff from mpi.c to comply with ISO C  :-)
+       
+Jun 11th, 2003
+v0.85  -- Swapped in a new AES routine
+       -- Removed Serpent
+       -- Added TDCAL policy document
+       
+Jun 1st, 2003
+v0.84  -- Removed a 4KB buffer from rsa_decrypt_key that wasn't being used no more
+       -- Fixed another potential buffer problem.  Not an overflow but could cause the 
+          PK import routines to read past the end of the buffer.
+       -- Optimized the ECC mulmod more by removing a if condition that will always be false
+       -- Optimized prime.c to not include a 2nd prime table, removed code from is_prime calls prime
+          test from LibTomMath now
+       -- Added LTC_TEST define which when defined will enable the test vector routines [see mycrypt_custom.h]
+       -- Removed ampi.o from the depends cuz it ain't no not working in *nix with it [routines are in mpi.c now].
+        
+
+Mar 29th, 2003
+v0.83  -- Optimized the ecc_mulmod, it's faster and takes less heap/stack space
+       -- Fixed a free memory error in ecc_mulmod and del_point which would try to free NULL
+       -- Fixed two serious bugs in rsa_decrypt_key and rsa_verify_hash that would allow a trivialy
+          buffer overflow.
+       -- Fixed a bug in the hmac testing code if you don't register all the hashes it won't return
+          errors now.
+       
+Mar 15th, 2003
+v0.82  -- Manual updated
+       -- Added MSVC makefile [back, actually its written from scratch to work with NMAKE]
+       -- Change to HMAC helper functions API to avoid buffer overflow [source changes]
+       -- the rsa_encrypt_key was supposed to reject key sizes out of bounds ... 
+          same fix to the rsa_sign_hash 
+       -- Added code to ensure that that chaining mode code (cfb/ofb/ctr/cbc) have valid
+          structures when being called.  E.g. the indexes to the pad/ivs are not out of bounds
+       -- Cleaned up the DES code and simplified the core desfunc routine.
+       -- Simplified one of the boolean functions in MD4
+       
+Jan 16th, 2003
+v0.81  -- Merged in new makefile from Clay Culver and Mike Frysinger
+       -- Sped up the ECC mulmod() routine by making the word size adapt to the input.  Saves a whopping 9 point
+          operations on 521-bit keys now (translates to about 8ms on my Athlon XP).  I also now use barrett reduction
+          as much as possible.  This sped the routine up quite a bit.
+       -- Fixed a huge flaw in ecc_verify_hash() where it would return CRYPT_OK on error... Now fixed.
+       -- Fixed up config.pl by fixing an invalid query and the file is saved in non-windows [e.g. not CR/LF] format
+          (fix due to Mika Boström)
+       -- Merged in LibTomMath for kicks
+       -- Changed the build process so that by default "mycrypt_custom.h" is included and provided
+          The makefile doesn't include any build options anymore
+       -- Removed the PS2 and VC makefiles.
+       
+Dec 16th, 2002
+v0.80  -- Found a change I made to the MPI that is questionable.  Not quite a bug but definately not desired.  Had todo
+          with the digit shifting.  In v0.79 I simply truncated without zeroing.  It didn't cause problems during my
+          testing but I fixed it up none the less.
+       -- Optimized s_mp_mul_dig() from MPI to do a minimal number of passes.
+       -- Fixed in rsa_exptmod() where I was getting the size of the result.  Basically it accomplishes the same thing
+          but the fixed code is more readable.
+       -- Fixed slight bug in dh_sign_hash() where the random "k" value was 1 byte shorter than it should have been.  I've
+          also made the #define FAST_PK speed up signatures as well.  Essentially FAST_PK tells the DH sub-system to 
+          limit any private exponent to 256-bits.   Note that when FAST_PK is defined does not make the library
+          binary or source incompatible with a copy of the library with it undefined.
+       -- Removed the DSA code.  If you want fast diffie-hellman just define FAST_PK :-)
+       -- Updated dh_sign_hash()/dh_verify_hash() to export "unsigned" bignums.  Saves two bytes but is not binary
+          compatible with the previous release... sorry!  I've performed the same fix to the ecc code as well.
+       -- Fixed up the PK code to remove all use of mp_toraw() and mp_read_raw() [get all the changes out of the way now]
+       -- Fixed a bug in the DH code where it missed trapping a few errors if they occurred.
+       -- Fixed a slight "its-not-a-bug-but-could-be-done-better" bug in the next_prime() function.  Essentially it was
+          testing to ensure that in the loop that searches for the next candidate that the step never grows beyond
+          65000.  Should have been testing for MP_DIGIT_MAX
+       -- Spruced up the config.pl script.  It now makes a header file "mycrypt_custom.h" which can be included *before*
+          you include mycrypt.h.  This allows you to add libtomcrypt to a project without completely changing your make
+          system around.  Note that you should use the makefile it writes to at least build the library initially.
+       -- Used splint to check alot of the code out.  Tons of minor fixes and explicit casts added.
+       -- Also made all the internal functions of MPI are now static to avoid poluting the namespace
+       -- **Notice**:  There are no planned future releases for at least a month from the this release date.
+       
+Dec 14th, 2002
+v0.79  -- Change to PK code [binary and source].  I made it so you have to pass the buffer size to the *_decrypt_key and
+          *_verify_hash functions.  This prevents malformed packets from performing buffer overflows.  I've also trimmed
+          the packet header size [by 4 bytes].
+       -- Made the test program halt on the first error it occurs.  Also made it trap more errors than before.
+       -- Wrote the first chapter of my new book [DRAFT!], not in this package but check my website!
+       -- Included a perl script "config.pl" that will make "makefile.out" according to the users needs.  
+       -- Added shell script to look for latest release
+       -- Merge DH and ECC key defines from mycrypt_cfg.h into the makefiles
+       -- updated the makefile to use BSD friendly archiving invokations
+       -- Changed the DH and ECC code to use base64 static key settings [e.g. the primes].  Dropped the code size by 3KB
+          and is ever-so-slightly faster than before.
+       -- added "mp_shrink" function to shrink the size of bignums.  Specially useful for PK code :-)
+       -- Added new exptmod function that calculates a^b mod c with fewer multiplies then before [~20% for crypto
+          sized numbers].  Also added a "low mem" variant that doesn't use more than 20KB [upto 4096 bit nums] of
+          heap todo the calculation.  Both are #define'able controlled
+       -- Added XREALLOC macro to provide realloc() functionality.
+       -- Added fix where in rsa_import() if you imported a public key or a non-optimized key it would free the mp_int's
+          not being used.
+       -- Fixed potential bug in the ECC code.  Only would occur on platforms where char is not eight bits [which isn't
+          often!]
+       -- Fixed up the ECC point multiplication, its about 15% faster now
+       -- While I was at it [since the lib isn't binary backwards compatible anyways] I've fixed the PK export routines
+          so they export as "unsigned" types saving 1 byte per bignum outputted.  Not a lot but heck why not.
+          
+Nov 28th, 2002
+v0.78  -- Made the default ARGCHK macro a function call instead which reduced the code size from 264KB to 239KB.
+       -- Fixed a bug in the XTEA keysize function which called ARGCHK incorrectly.
+       -- Added Noekeon block cipher at 2,800 bytes of object code and 345Mbit/sec it is a welcome addition.
+       -- Made the KR code check if the other PK systems are included [provides error when building otherwise].
+       -- Made "aes" an alias for Rijndael via a pre-processor macro.  Now you can use "aes_ecb_encrypt", etc... :-)
+          Thanks to Jean-Luc Cooke for the "buzzword conformance" suggestion.
+       -- Removed the old PK code entirely (e.g. rsa_sign, dh_encrypt).  The *_sign_hash and *_encrypt_key functions
+          are all that is to remain.
+       -- **NOTE** Changed the PK *_import (including the keyring) routine to accept a "inlen" parameter.  This fixes a
+          bug where improperly made key packets could result in reading passed the end of the buffer.  This means
+          the code is no longer source compatible but still binary compatible.
+       -- Fixed a few other minor bugs in the PK import code while I was at it.
+       
+Nov 26th, 2002
+v0.77  -- Updated the XTEA code to use pre-computed keys.  With optimizations for speed it achieves 222Mbit/sec
+          compared to the 121Mbit/sec before.  It is 288 bytes bigger than before.
+       -- Cleaned up some of the ciphers and hashes (coding style, cosmetic changes)
+       -- Optimized AES slightly for 256-bit keys [only one if statement now, still two for 192-bit keys]
+       -- Removed most test cases from Blowfish, left three of them there.  Makes it smaller and faster to test.
+       -- Changed the primality routines around.  I now use 8 rounds of Rabin-Miller, I use 256 primes in the sieve
+          step and the "rand_prime" function uses a modified sieve that avoids alot of un-needed bignum work.
+       -- Fixed a bug in the ECC/DH signatures where the keys "setting" value was not checked for validity.  This means
+          that a invalid value could have caused segfaults, etc...
+       -- **NOTE** Changed the way the ECC/DH export/import functions work.  They are source but not binary compatible
+          with v0.76.  Essentially insteading of exporting the setting index like before I export the key size.  Now
+          if you ever re-configure which key settings are supported the lib will still be able to make use of your 
+          keys.
+       -- Optimized Blowfish by inlining the round function, unrolling it for four rounds then using a for loop for the 
+          rest.  It achieves a rate of 425Mbit/sec with the new code compared to 314Mbit/sec before.  The new blowfish 
+          object file is 7,813 bytes compared to 8,663 before and is 850 bytes smaller.  So the code is both smaller and 
+          faster!
+       -- Optimized Twofish as well by inlining the round function.  Gets ~400Mbit/sec compared to 280Mbit/sec before
+          and the code is only 78 bytes larger than the previous copy.
+       -- Removed SMALL_PRIME_TAB build option.  I use the smaller table always.
+       -- Fixed some mistakes concerning prime generation in the manual.
+       -- [Note: sizes/speeds are for GCC 3.2 on an x86 Athlon XP @ 1.53Ghz]
+
+Nov 25th, 2002
+v0.76  -- Updated makefiles a bit more, use "-Os" instead of "-O2" to optimize for size.  Got the lib
+          downto 265KB using GCC 3.2 on my x86 box.
+       -- Updated the SAFER+, Twofish and Rijndael test vector routine to use the table driven design.
+       -- Updated all other test vector routines to return as soon as an error is found
+       -- fixed a bug in the test program where errors in the hash test routines would not be reported
+          correctly.  I found this by temporarily changing one of the bytes of the test vectors.  All the
+          hashes check out [the demos/test.c would still have reported an error, just the wrong one].
+          
+
+Nov 24th, 2002
+v0.75  -- Fixed a flaw in hash_filehandle, it should ARGCHK that the filehandle is not NULL
+       -- Fixed a bug where in hash_file if the call to hash_filehandle failed the open file would 
+          not be closed.
+       -- Added more strict rules to build process, starting to weed out "oh this works in GCC" style code
+          In the next release "-Wconversion" will be enabled which will deal with all implicit casts.
+
+Nov 22nd, 2002 [later in the day]
+v0.74  -- Wrote a small variant of SAFER+ which shaved 50KB off the size of the library on x86 platforms
+       -- Wrote a build option to remove the PK packet functions [keeps the encrypt_key/sign_hash functions]
+       -- Wrote a small variant of Rijndael (trimmed 13KB)
+       -- Trimmed the TIGER/192 hash function a bit
+       -- Overall the entire lib compiled is 295KB [down from 400KB before]
+       -- Fixed a few minor oversights in the MSVC makefile
+
+Nov 22nd, 2002
+v0.73  -- Fixed bug in RC4 code where it could only use 255 byte keys.
+       -- Fixed bug in yarrow code where it would allow cast5 or md2 to be used with it...
+       -- Removed the ecc compress/expand points from the global scope.  Reduces namespace polution
+       -- Fixed bug where if you used the SPRNG you couldn't pass NULL as your prng_state which you should be
+          able todo since the SPRNG has no state...
+       -- Corrected some oversights in the manual and the examples...
+       -- By default the GF(2^W) math library is excluded from the build.  The source is maintained because I wrote it
+          and like it :-).  This way the built library is a tad smaller
+       -- the MSVC makefile will now build for a SPACE optimized library rather than TIME optimized.
+
+Nov 21th, 2002
+v0.72  -- Fixed bug in the prime testing.  In the Miller-Rabin test I was raising the base to "N-1" not "r".
+          The math still worked out fine because in effect it was performing a Fermat test.  Tested the new code and it 
+          works properly
+       -- Fixed some of the code where it was still using the old error syntax
+       -- Sped up the RSA decrypt/sign routines
+       -- Optimized the ecc_shared_secret routine to not use so much stack
+       -- Fixed up the makefile to make releases where the version # is in the file name and directory it will unzip
+          to
+
+Nov 19th, 2002
+v0.71  -- HELP TOM.  I need tuition for the January semester.  Now I don't want to force donations [nor will I ever]
+          but I really need the help!  See my website http://tom.iahu.ca/help_tom.html for more details.  Please help
+          if you can! 
+       --------------------------------------------------------------------------------------------------------------
+       -- Officially the library is no longer supported in GCC 3.2 in windows [cygwin].
+          In windows you can either use GCC 2.95.3 or try your luck with 3.2  It seems that
+          "-fomit-frame-pointer" is broken in the windows build [but not the linux x86 build???]
+          If you simply must use 3.2 then I suggest you limit the optimizations to simply "-O2"
+       -- Started new error handling API.  Similar to the previous except there are more error codes than just
+          CRYPT_ERROR
+       -- Added my implementation of the MD2 hash function [despite the errors in the RFC I managed to get it right!]
+       -- Merged in more changes from Sky Schulz.  I have to make mention here that he has been a tremendous help in 
+          getting me motivated to make some much needed updates to the library!
+       -- Fixed one of the many mistakes in the manual as pointed out by Daniel Richards
+       -- Fixed a bug in the RC4 code [wasn't setting up the key correctly]
+       -- Added my implementation of the CAST5 [aka CAST-128] block cipher (conforms...)
+       -- Fixed numerous bugs in the PK code.  Essentially I was "freeing" keys when the import failed.  This is neither
+          required nor a good a idea [double free].  
+       -- Tom needs a job.
+       -- Fixed up the test harness as requested by Sky Schulz.  Also modifed the timing routines to run for X seconds
+          and count # of ops performed.  This is more suitable than say encrypting 10 million blocks on a slow processor
+          where it could take minutes!
+       -- Modified test programs hashsum/encrypt to use the new algorithms and error handling syntax
+       -- Removed the PKCS code since it was incomplete.  In the future I plan on writing a "add-on" library that
+          provides PKCS support... 
+       -- updated the config system so the #defines are in the makefiles instead of mycrypt_cfg.h  
+       -- Willing to work on an hourly basis for 15$ CDN per hour.
+       -- updated the test program to not test ciphers not included
+       -- updated the makefile to make "rsa_sys.c" a dependency of rsa.o [helps develop the code...]
+       -- fixed numerous failures to detect buffer overflows [minor] in the PK code.
+       -- fixed the safer [64-bit block version] test routines which didn't check the returns of the setup
+          function
+       -- check out my CV at http://tom.iahu.ca/cv.html
+       -- removed the GBA makefile and code from demos/test.c [not a particularly useful demo...]
+       -- merged in rudimentary [for testing] PS2 RNG from Sky Schulz
+       -- merged in PS2 timer code [only shell included due to NDA reasons...]
+       -- updated HMAC code to return errors where possible
+       -- Thanks go to Sky Schulz who bought me a RegCode for TextPad [the official editor of libtomcrypt]
+
+Nov 12th, 2002
+v0.70  -- Updated so you can swap out the default malloc/calloc/free routines at build time with others. (Sky Schulz)
+       -- Sky Schulz contributed some code towards autodetecting the PS2 in mycrypt_cfg.h
+       -- Added PS2 makefile contributed by Sky Schulz [see a pattern forming?]
+       -- Added ability to have no FILE I/O functions at all (see makefile), Sky Schulz....
+       -- Added support for substituting out the clock() function (Sky Schulz)
+       -- Fixed up makefile to include new headers in the HEADERS variable
+       -- Removed "coin.c" as its not really useful anyways
+       -- Removed many "debug" printfs that would show up on failures.  Basically I wanted to ensure the only output
+          would be from the developer themselves.
+       -- Added "rc4.c" a RC4 implementation with a PRNG interface.  Since RC4 isn't a block cipher it wouldn't work
+          too well as a block cipher.
+       -- Fixed ARGCHK macro usage when ARGTYPE=1 throughout the code
+       -- updated makefile to make subdirectory properly (Sku Schulz)
+       -- Started towards new API setup.  Instead of checking for "== CRYPT_ERROR" you should check "!= CRYPT_OK"
+          In future releases functions will return things other than CRYPT_ERROR on error to give more useful
+          thread safe error reporting.  The manual will be updated to reflect this.  For this release all
+          errors are returned as CRYPT_ERROR (except as noted) but in future releases this will change.         
+       -- Removed the zlib branch since its not really required anyways.  Makes the package smaller
+
+Nov 11th, 2002
+v0.69  -- Added ARGCHK (see mycrypt_argchk.h) "arguement checking" to all functions that accept pointers
+       -- Note I forgot to change the CRYPT version tag in v0.68... fixed now.
+
+Nov 8th, 2002
+v0.68  -- Fixed flaw in kr_import/kr_export that wasted 4 bytes.  Source but not binary compatible with v0.67
+       -- Fixed bug in kr_find_name that used memcmp to match strings.  Uses strncmp now.
+       -- kr_clear now sets the pointer to NULL to facilate debugging [e.g. using the keyring after clearing]
+       -- static functions in _write/_read in keyring.c now check the return of ctr_encrypt/ctr_decrypt.
+       -- Updated blowfish/rc2/rc5/rc6 keysize() function to not reject keys larger than the biggest key the
+          respective ciphers can use.  
+       -- Fixed a bug in hashsum demo that would report the hash for files that don't exist!
+
+Oct 16th, 2002
+v0.67  -- Moved the function prototypes into files mycrypt_*.h.  To "install" the lib just copy all the 
+          header files "*.h" from the base of this project into your global include path.
+       -- Made the OFB/CFB/CTR functions use "unsigned long" for the length instead of "int"
+       -- Added keyring support for the PK functions
+       -- ***API CHANGE*** changed the ecc_make_key and dh_make_key to act more like rsa_make_key.  Basically
+          move the first argument to the next to last.
+       -- Fixed bug in dh_test() that wouldn't test the primality of the order of the sub-group
+       -- replaced the primes in the DH code with new ones that are larger than the size they are 
+          associated with.  That is a 1024-bit DH key will have a 1025-bit prime as the modulus
+       -- cleaned up all the PK code, changed a bit of the API around [not source compatible with v0.66]
+       -- major editing of the manual, started Docer program
+       -- added 160 and 224 bit key settings for ECC.  This makes the DH and ECC binary wise incompatible with v0.66
+       -- Added an additional check for memory errors in is_prime() and cleaned up prime.c a bit
+       -- Removed ID_TAG from all files [meh, not a big fan...]
+       -- Removed unused variable from yarrow state and made AES/SHA256 the default cipher/hash combo
+       -- Fixed a bug in the Yarrow code that called prng_is_valid instead of cipher_is_valid from yarrow_start()
+       -- The ECB/CBC/OFB/CFB/CTR wrappers now check that the cipher is valid in the encrypt/decrypt calls
+          Returns int now instead of void.
+
+Sept 24th, 2002
+v0.66  -- Updated the /demos/test.c program to time the hashes correctly.  Also it uses the yarrow PRNG for all of the 
+          tests meaning its possible to run on RNG less platforms 
+       -- Updated the /demos/hashsum.c program to hash from the standard input
+       -- Updated the RSA code to make keys a bit quicker [update by Wayne Scott] by not making both primes at the same
+          time.
+       -- Dan Kaminsky suggested some cleanups for the code and the MPI config
+          Code ships in unix LF format by default now too... will still build in MSVC and all... but if you want
+          to read the stuff you'll have to convert it 
+       -- Changes to the manual to reflect new API [e.g. hash_memory/file have v0.65 prototypes]and some typos fixed
+
+Sept 20th, 2002
+v0.65  -- Wayne Scott (wscott@bitmover.com) made a few of suggestions to improve the library.  Most 
+          importantly he pointed out the math lib is not really required.  He's also tested the lib on 18 
+          different platforms.  According to him with only a few troubles [lack of /dev/random, etc] the 
+          library worked as it was supposed to.  You can find the list at 
+          http://www.bitkeeper.com/Products.BitKeeper.Platforms.html
+       -- Updated the hash_file and hash_memory functions to keep track of the size of the output
+       -- Wayne Scott updated the demos/test.c file to use the SPRNG less and Yarrow more
+       -- Modified the mycrypt_cfg.h to autodetect x86-32 machines
+
+Sept 19th, 2002
+v0.64  -- wrote makefile for the GBA device [and hacked the demos/test.c file to support it conditionally]
+       -- Fixed error in PK (e.g. ECC, RSA, DH) import functions where I was clobbering the packet error messages
+       -- fixed more typos in the manual
+       -- removed all unused variables from the core library (ignore the ID_TAG stuff)
+       -- added "const char *crypt_build_settings" string which is a build time constant that gives a listing
+          of all the build time options.  Useful for debugging since you can send that to me and I will know what 
+          exactly you had set for the mycrypt_cfg.h file.
+       -- Added control over endianess.  Out of the box it defaults to endianess neutral but you can trivially 
+          configure the library for your platform.  Using this I boosted RC5 from 660Mbit/sec to 785Mbit/sec on my 
+          Athlon box.  See "mycrypt_cfg.h" for more information.
+
+Sept 11th, 2002
+v0.63  -- Made hashsum demo output like the original md5sum program 
+       -- Made additions to the examples in the manual (fixed them up a bunch)
+       -- Merged in the base64 code from Wayne Scott (wscott@bitmover.com)
+
+Aug 29th, 2002
+v0.62  -- Added the CLEAN_STACK functionality to several of the hashes I forgot to update.
+
+Aug 9th, 2002
+v0.61  -- Fixed a bug in the DES code [oops I read something wrong].
+
+Aug 8th, 2002
+v0.60  -- Merged in DES code [and wrote 3DES-EDE code based on it] from Dobes V.
+
+Aug 7th, 2002
+v0.59  -- Fixed a "unsigned long long" bug that caused v0.58 not to build in MSVC.
+       -- Cleaned up a little in the makefile
+       -- added code that times the hash functions too in the test program
+
+Aug 3rd, 2002
+v0.58  -- Added more stack cleaning conditionals throughout the code.  
+       -- corrected some CLEAR_STACK conditionals... should have been CLEAN_STACK
+       -- Simplified the RSA, DH and ECC encrypt() routines where they use CTR to encode the message
+          now they only make one call to ctr_encrypt()/ctr_decrypt().
+
+Aug 2nd, 2002
+v0.57  -- Fixed a few errors messages in the SAFER code to actually report the correct cipher name.
+       -- rsa_encrypt() uses the "keysize()" method of the cipher being used to more accurately pick a
+          key size.  By default rsa_encrypt() will choose to use a 256-bit key but the cipher can turn that 
+          down if required.
+       -- The rsa_exptmod() function will now more reliably detect invalid inputs (e.g. greater than the modulus).
+       -- The padding method for RSA is more clearly documented.  Namely if you want to encrypt/sign something of length
+          N then your modulus must be of length 1+3N.  So to sign a message with say SHA-384 [48 bytes] you need a 
+          145 byte (1160 bits) modulus.  This is all in the manual now.
+       -- Added build option CLEAN_STACK which will allow you to choose whether you want to clean the stack or not after every
+          cipher/hash call
+       -- Sped up the hash "process()" functions by not copying one byte at a time.
+       ++ (added just after I uploaded...)
+          MD4 process() now handles input buffers > 64 bytes
+
+Aug 1st, 2002
+v0.56  -- Cleaned up the comments in the Blowfish code.
+       -- Oh yeah, in v0.55 I made all of the descriptor elements constant.  I just forgot to mention it.
+       -- fixed a couple of places where descriptor indexes were tested wrong.  Not a huge bug but now its harder
+          to mess up.
+       -- Added the SAFER [64-bit block] ciphers K64, SK64, K128 and SK128 to the library.
+       -- Added the RC2 block cipher to the library.
+       -- Changed the SAFER define for the SAFER+ cipher to SAFERP so that the new SAFER [64-bit] ciphers
+          can use them with less confusion.
+
+July 29th, 2002
+v0.55  -- My god stupid Blowfish has yet again been fixed.  I swear I hate that cipher.  Next bug in it and boom its out of the
+          library.  Use AES or something else cuz I really hate Blowfish at this stage....
+       -- Partial PKCS support [hint DONT USE IT YET CUZ ITS UNTESTED!]
+
+July 19th, 2002
+v0.54  -- Blowfish now conforms to known test vectors.  Silly bad coding tom!
+       -- RC5/RC6/Serpent all have more test vectors now [and they seemed to have been working before]
+
+July 18th, 2002
+v0.53  -- Added more test vectors to the blowfish code just for kicks [and they are const now too :-)]
+       -- added prng/hash/cipher is_valid functions and used them in all of the PK code so you can't enter the code
+          with an invalid index ever now.
+       -- Simplified the Yarrow code once again :-)
+
+July 12th, 2002
+v0.52  -- Fixed a bug in MD4 where the hash descriptor ID was the same as SHA-512.  Now MD4 will work with
+          all the routines...
+       -- Fixed the comments in SHA-512 to be a bit more meaningful
+       -- In md4 I made the PADDING array const [again to store it in ROM]
+       -- in hash_file I switched the constant "512" to "sizeof(buf)" to be a bit safer
+       -- in SHA-1's test routine I fixed the string literal to say SHA-1 not sha1
+       -- Fixed a logical error in the CTR code which would make it skip the first IV value.  This means
+          the CTR code from v0.52 will be incompatible [binary wise] with previous releases but it makes more
+          sense this way.
+       -- Added {} braces for as many if/for/blocks of code I could find.  My rule is that every for/if/while/do block
+          must have {} braces around it.
+       -- made the rounds table in saferp_setup const [again for the ROM think about the ROM!]
+       -- fixed RC5 since it no longer requires rc5 to be registered in the lib.  It used to since the descriptors used to 
+          be part of the table...
+       -- the packet.c code now makes crypt_error literal string errors when an error occurs
+       -- cleaned up the SAFER+ key schedule to be a bit easier to read.
+       -- fixed a huge bug in Twofish with the TWOFISH_SMALL define.  Because I clean the stack now I had
+          changed the "g_func()" to be called indirectly.  I forgot to actually return the return of the Twofish
+          g_func() function which caused it not to work... [does now :-)]
+
+July 11th, 2002
+v0.51  -- Fixed a bug in SHA512/384 code for multi-block messages.
+       -- Added more test vectors to the SHA384/512 and TIGER hash functions
+       -- cleaned up the hash done routines to make more sense
+ 
+July 10th, 2002
+v0.50  -- Fixed yarrow.c so that the cipher/hash used would be registered.  Also fixed
+          a bug where the SAFER+ name was "safer" but should have been "safer+".
+       -- Added an element to the hash descriptors that gives the size of a block [sent into the compressor]
+       -- Cleaned up the support for HMAC's
+       -- Cleaned up the test vector routines to make the test vector data const.  This means on some platforms it will be
+          placed in ROM not RAM now.
+       -- Added MD4 code submited by Dobes Vandermeer (dobes@smartt.com)
+       -- Added "burn_stack" function [idea taken from another source of crypto code].  The idea is if a function has
+          alot of variables it will clean up better.  Functions like the ecb serpent and twofish code will now have their
+          stacks cleaned and the rest of the code is getting much more straightforward.
+       -- Added a hashing demo by Daniel Richards (kyhwana@world-net.co.nz)
+       -- I (Tom) modified some of the test vector routines to use more vectors ala Dobes style.
+          For example, the MD5/SHA1 code now uses all of the test vectors from the RFC/FIPS spec.
+       -- Fixed the register/unregister functions to properly report errors in crypt_error
+       -- Correctly updated yarrow code to remove a few unused variables.
+       -- Updated manual to fix a few erroneous examples.
+       -- Added section on Hash based Message Authentication Codes (HMAC) to the manual
+
+June 19th, 2002
+v0.46  -- Added in HMAC code from Dobes Vandermeer (dobes@smartt.com)
+
+June 8th, 2002
+v0.45  -- Fixed bug in rc5.c where if you called rc5_setup() before registering RC5 it would cause
+          undefined behaviour.
+       -- Fixed mycrypt_cfg.h to eliminate the 224 bit ECC key.
+       -- made the "default" makefile target have depends on mycrypt.h and mycrypt_cfg.h
+
+Apr 4th, 2002
+v0.44  -- Fixed bug in ecc.c::new_point() where if the initial malloc fails it would not catch it.
+
+Mar 22nd, 2002
+v0.43  -- Changed the ZLIB code over to the 1.1.4 code base to avoid the "double free" bug.  
+       -- Updated the GCC makefile not to use -O3 or -funroll-loops
+       -- Version tag in mycrypt.h has been updated :-)
+
+Mar 10th, 2002
+v0.42  -- The RNG code can now use /dev/urandom before trying /dev/random (J. Klapste)
+
+Mar 3rd, 2002
+v0.41  -- Added support to link and use ciphers at compile time.  This can greatly reduce the code size!
+       -- Added a demo to show off how small an application can get... 46kb!
+       -- Disastry pointed out that Blowfish is supposed to be high endian.
+       -- Made registry code for the PRNGs as well [now the smallest useable link is 43kb]
+
+Feb 11th, 2002
+v0.40  -- RSA signatures use [and check for] fixed padding scheme.
+       -- I'm developing in Linux now :-)
+       -- No more warnings from GCC 2.96
+
+Feb 5th, 2002
+v0.39  -- Updated the XTEA code to work in accordance with the XTEA design
+
+January 24th, 2002
+v0.38  -- CFB and OFB modes can now handle blocks of variable size like the CTR code
+       -- Wrote a wrapper around the memory compress functions in Zlib that act like the functions
+          in the rest of my crypto lib
+
+January 23rd, 2002
+v0.37  -- Added support code so that if a hash size and key size for a cipher don't match up they will
+          use the next lower key supported.  (mainly for the PK code).  So you can now use SHA-1 with
+          Twofish, etc...
+       -- Added more options for Twofish.  You can now tell it to use precomputed sboxes and MDS multiplications
+          This will speed up the TWOFISH_SMALL implementation by increasing the code size by 1024 bytes.
+       -- Fixed a bug in prime.c that would not use the correct table if you undefined SMALL_PRIME_TAB
+       -- Fixed all of the PK packet code to use the same header format [see packet.c].  This makes the PK code
+          binary wise incompatible with previous releases while the API has not changed at all.
+
+January 22nd, 2002
+v0.36  -- Corrections to the manual
+       -- Made a modification to Twofish which lets you build a "small ram" variant.  It requires
+          about 190 bytes of ram for the key storage compared to the 4,200 bytes the normal 
+          variant requires.
+       -- Reduced the stack space used in all of the PK routines.
+
+January 19th, 2002
+v0.35  -- If you removed the first hash or cipher from the library it wouldn't return an error if 
+          you used an ID=0 [i.e blowfish or sha256] in any routine.  Now it checks for that and will
+          return an error like it should
+       -- Merged in new routines from Clay Culver.  These routines are for the PK code so you can easily 
+          encode a symmetric key for multiple recipients.
+       -- Made the ecc and DH make_key() routines make secret keys of the same size as the keysize listed.
+          Originally I wanted to ensure that the keys were smaller than the order of the field used
+          However, the bias is so insignifcant using full sizes.  For example, with a ECC-192 key the order
+          is about 2^191.99, so instead I rounded down and used a 184-bit secret key.  Now I simply use a full 192-bit
+          key the code will work just the same except that some 192-bit keys will be duplicates which is not a big
+          deal since 1/2^192 is a very small bias!
+       -- Made the configuration a bit simpler and more exacting.  You can for example now select which DH or ECC
+          key settings you wish to support without including the data for all other key settings.  I put the #defines
+          in a new file called "mycrypt_cfg.h"
+       -- Configured "mpi-config.h" so its a bit more conservative with the memory required and code space used
+       -- Jason Klapste submitted bug fixes to the yarrow, hash and various other issues.  The yarrow code will now
+          use what ever remaining hash/cipher combo is left [after you #undef them] at build time.   He also suggested
+          a fix to remove unused structures from the symmetric_key and hash_state unions.
+       -- Made the CTR code handle variable length blocks better. It will buffer the encryption pad so you can
+          encrypt messages any size block at a time.
+       -- Simplified the yarrow code to take advantage of the new CTR code.
+       -- Added a 4096-bit DH key setting.  That took me about 36 hours to find!
+       -- Changed the base64 routines to use a real base64 encoding scheme.
+       -- Added in DH and ECC "encrypt_key()" functions.  They are still rather "beta"ish.
+       -- Added **Twofish** to the list of ciphers!
+
+January 18th, 2002
+v0.34  -- Added "sha512" to the list of hashes.  Produces a 512-bit message digest.  Note that with the current
+          padding with the rsa_sign() function you cannot use sha512 with a key less than 1536 bits for signatures.
+       -- Cleaned up the other hash functions to use the LOAD and STORE macros...
+
+January 17th, 2002
+v0.33  -- Made the lower limit on keysizes for RSA 1024 bits again because I realized that 768 bit keys wouldn't
+          work with the padding scheme and large symmetric keys.
+       -- Added information concerning the Zlib license to the manual
+       -- Added a 3072-bit key setting for the DH code.
+       -- Made the "find_xyz()" routines take "const char *" as per Clay Culver's suggestion.
+       -- Fixed an embarassing typo in the manual concerning the hashes.  Thank's Clay for finding it!
+       -- Fixed rand_prime() so that it makes primes bigger than the setting you give.  For example,
+          if you want a 1024-bit prime it would make a 1023-bit one.  Now it ensures that the prime
+          it makes is always greater than 2^(8n) (n == bytes in prime).  This doesn't have a huge
+          impact on security but I corrected it just the same.
+       -- Fixed the CTR routine to work on platforms where char != 8-bits 
+       -- Fixed sha1/sha256/md5/blowfish to not assume "unsigned long == 32-bits", Basically any operation with carries
+          I "AND" with 0xFFFFFFFF.  That forces only the lower 32-bits to have information in it.  On x86 platforms
+          most compilers optimize out the AND operation since its a nop.
+
+January 16th, 2002
+v0.32  -- Made Rijndael's setup function fully static so it is thread safe
+       -- Svante Seleborg suggested a cosmetic style fixup for aes.c, 
+          basically to remove some of the #defines to clean it up
+       -- Made the PK routines not export the ASCII version of the names of ciphers/hashes which makes
+          the PK message formats *incompatible* with previous releases.
+       -- Merge in Zlib :-)
+ 
+  
+January 15th, 2002
+v0.31  -- The RSA routines can now use CRT to speed up decryption/signatures.  The routines are backwards 
+          compatible with previous releases.
+       -- Fixed another bug that Svante Seleborg found.  Basically you could buffer-overrun the 
+          rsa_exptmod() function itself if you're not careful.  That's fixed now.  Fixed another bug in
+          rsa_exptmod() where if it knows the buffer you passed is too small it wouldn't free all used 
+          memory.       
+       -- improved the readability of the PK import/export functions
+       -- Added a fix to RSA.C by Clay Culver
+       -- Changed the CONST64 macro for MSVC to use the "unsigned __int64" type, e.g. "ui64" instead of "i64".
+
+January 14th, 2002
+v0.30  -- Major change to the Yarrow PRNG code, fixed a bug that Eugene Starokoltsev found.
+          Basically if you added entropy to the pool in small increments it could in fact
+          cancel out.  Now I hash the pool with the new data which is way smarter.
+
+January 12th, 2002
+v0.29  -- Added MPI code written by Svante Seleborg to the library.  This will make the PK code much
+          easier to follow and debug.  Actually I've already fixed a memory leak in dh_shared_secret().
+       -- Memory leaks found and correct in all three PK routines.  The leaks would occur when a bignum
+          operation fails so it wouldn't normally turn up in the course of a program
+       -- Fixed bugs in dh_key_size and ecc_key_size which would return garbage for invalid key idx'es
+
+January 11th, 2002
+v0.28  -- Cleaned up some code so that it doesn't assume "char == 8bits".  Mainly SAFER+ has been 
+          changed.
+       -- ***HUGE*** changes in the PK code.  I check all return values in the bignum code so if there
+          are errors [insufficient memory, etc..] it will be reported.  This makes the code fairly more
+          robust and likely to catch any errors.
+       -- Updated the is_prime() function to use a new prototype [it can return errors now] and it also
+          does trial divisions against more primes before the Rabin Miller steps
+       -- Added OFB, CFB and ECB generic wrappers for the symmetric ciphers to round out the implementations.
+       -- Added Xtea to the list of ciphers, to the best of my ability I have verified this implementation.
+          I should note that there is not alot of concrete information about the cipher.  "Ansi C" versions
+          I found did not address endianess and were not even portable!.  This code is portable and to the
+          best of my knowledge implements the Xtea algorithm as per the [short] X-Tea paper.
+       -- Reformated the manual to include the **FULL** source code optimized to be pritable.
+
+January 9th, 2002
+v0.27  -- Changed the char constants to numerical values.  It is backwards compatible and should work on
+          platforms where 'd' != 100 [for example].
+       -- Made a change to rand_prime() which takes the input length as a signed type so you can pass
+          a negative len to get a "3 mod 4" style prime... oops
+       -- changed the MSVC makefile to build with a warning level of three, no warnings!
+
+January 8th, 2002
+v0.26  -- updated SHA-256 to use ROR() for a rotate so 64-bit machines won't corrupt
+          the output
+       -- Changed #include <> to #include "" for local .h files as per Richard Heathfields' suggestions.
+       -- Fixed bug in MPI [well bug in MSVC] that compiled code incorrectly in mp_set_int()
+          I added a work around that catches the error and continues normally.
+
+January 8th, 2002
+v0.25  -- Added a stupid define so MSVC 6.00 can build the library.
+       -- Big thanks to sci.crypt and "Ajay K. Agrawal" for helping me port this to MSVC
+
+January 7th, 2002
+v0.24  -- Sped up Blowfish by unrolling and removing the swaps.
+       -- Made the code comply with more traditional ANSI C standards
+          Should compile with MSVC with less errors
+       -- moved the demos and documentation into their own directories
+          so you can easily build the library with other tool chains
+          by compiling the files in the root
+       -- converted functions with length of outputs to use 
+          "unsigned long" so 16-bit platforms will like this library more.
+
+January 5th, 2002
+v0.23  -- Fixed a small error in the MPI config it should build fine anywhere.
+
+January 4th, 2002
+v0.22  -- faster gf_mul() code
+       -- gf_shl() and gf_shr() are safe on 64-bit platforms now
+       -- Fixed an error in the hashes that Brian Gladman found.  
+          Basically if the message has exactly 56 bytes left to be 
+          compressed I handled them incorrectly.
+
+January 4th, 2002
+v0.21  -- sped up the ECC code by removing redundant divisions in the 
+          point add and double routines.  I also extract the bits more
+          efficiently in "ecc_mulmod()" now.
+       -- sped up [and documented] the rand_prime() function.  Now it just
+          makes a random integer and increments by two until a prime is found
+          This is faster since it doesn't require alot of calls to the PRNG and
+          it doesn't require loading huge integers over and over.  rand_prime()
+          can also make primes congruent to 3 mod 4 [i.e for a blum integer]
+       -- added a gf_sqrt() function that finds square roots in a GF(2^w) field
+       -- fixed a bug in gf_div() that would return the wrong results if the divisor had a greator
+          divisor than the dividend.
+
+January 4th, 2002
+v0.20  -- Added the fixed MPI back in so RSA and DH are much faster again
+
+v0.19  -- Updated the manual to reflect the fact that Brian Gladman wrote the AES and Serpent code.
+       -- DH, ECC and RSA signature/decryption functions check if the key is private
+       -- new DH signature/verification code works just like the RSA/ECC versions
+
+January 3rd, 2002
+v0.18  -- Added way more comments to each .C file 
+       -- fixed a bug in cbc_decrypt(pt, ct, key) where pt == ct [i.e same buffer]
+       -- fixed RC5 so it reads the default rounds out of the cipher_descriptor table
+       -- cleaned up ecc_export()
+       -- Cleaned up dh_import() and ecc_import() which also perform more 
+          error checking now
+       -- Fixed a serious flaw in rsa_import() with private keys.
+
+January 2nd, 2002
+v0.17  -- Fixed a bug in the random prime generator that fixes the wrong bits to one
+       -- ECC and DH code verify that the moduli and orders are in fact prime.  That 
+          slows down the test routines alot but what are you gonna do? 
+       -- Fixed a huge bug in the mp_exptmod() function which incorrectly calculates g^x mod p for some
+          values of p.  I replaced it with a slow function.  Once the author of MPI fixes his faster routine
+          I will switch back.
+  
+January 1st, 2002 [whoa new year!]
+v0.16  -- Improved GF division code that is faster.
+       -- documented the GF code
+
+December 31st, 2001
+v0.15  -- A 1792-bit and 2048-bit DH setting was added.  Took me all night to 
+          find a 1792 and 2048-bit strong prime but what the heck
+       -- Library now has polynomial-basis GF(2^w) routines I wrote myself.  Can be used to perform
+          ECC over GF(2^w) later on....
+       -- Fixed a bug with the defines that allows it to build in windows
+       
+December 30th, 2001
+v0.14  -- Fixed the xxx_encrypt() packet routines to make an IV of appropriate size 
+          for the cipher used.  It was defaulting to making a 256-bit IV...
+       -- base64_encode() now appends a NULL byte, um "duh" stupid mistake now fixed...
+       -- spell checked the manual again... :-)
+
+December 30th, 2001
+v0.13  -- Switching back to older copy of MPI since it works! arrg..
+       -- Added sign/verify functions for ECC
+       -- all signature verification routines default to invalid signatures.
+       -- Changed all calls to memset to zeromem.  Fixed up some buffer problems 
+          in other routines.  All calls to zeromem let the compiler determine the size
+          of the data to wipe.
+
+December 29th, 2001
+v0.12  -- Imported a new version of MPI [the bignum library] that should
+          be a bit more stable [if you want to write your own bignum
+          routines with the library that is...]
+       -- Manual has way more info
+       -- hash_file() clears stack now [like it should]
+       -- The artificial cap on the hash input size of 2^32 bits has been
+          removed.  Basically I was too lazy todo 64-bit math before
+          [don't ask why... I can't remember].  Anyways the hashes
+          support the size of 2^64 bits [if you ever use that many bits in a message
+          that's just wierd...]
+       -- The hashes now wipe the "hash_state" after the digest is computed.  This helps
+          prevent the internal state of the hash being leaked accidently [i.e stack problems]
+
+December 29th, 2001
+v0.11  -- Made #define's so you can trim the library down by removing
+          ciphers, hashs, modes of operation, prngs, and even PK algorithms
+          For example, the library with rijndael+ctr+sha1+ECC is 91KB compared
+          to the 246kb the full library takes.
+       -- Added ECC packet routines for encrypt/decrypt/sign/verify much akin to
+          the RSA packet routines.
+       -- ECC now compresses the public key, a ECC-192 public key takes 33 bytes 
+          for example....
+
+December 28th, 2001
+v0.10  -- going to restart the manual from scratch to make it more 
+          clear and professional
+       -- Added ECC over Z/pZ.  Basically provides as much as DH
+          except its faster since the numbers are smaller.  For example,
+          A comparable 256-bit ECC key provides as much security as expected
+          from a DH key over 1024-bits.
+       -- Cleaned up the DH code to not export the symbol "sets[]"
+       -- Fixed a bug in the DH code that would not make the correct size 
+          random string if you made the key short.  For instance if you wanted 
+          a 512-bit DH key it would make a 768-bit one but only make up 512-bits 
+          for the exponent... now it makes the full 768 bits [or whatever the case

+\chapter{Introduction}
+\section{What is the LibTomCrypt?}
+LibTomCrypt is a portable ISO C cryptographic library that is meant to be a toolset for cryptographers who are 
+designing a cryptosystem.  It supports symmetric ciphers, one-way hashes, pseudo-random number generators, 
+public key cryptography (via PKCS \#1 RSA, DH or ECCDH) and a plethora of support 
+routines.  
+
+The library was designed such that new ciphers/hashes/PRNGs can be added at runtime and the existing API 
+(and helper API functions) are able to use the new designs automatically.  There exists self-check functions for each 
+block cipher and hash function to ensure that they compile and execute to the published design specifications.  The library 
+also performs extensive parameter error checking to prevent any number of runtime exploits or errors.
+
+\subsection{What the library IS for?}
+
+The library serves as a toolkit for developers who have to solve cryptographic problems.  Out of the box LibTomCrypt
+does not process SSL or OpenPGP messages, it doesn't read x.591 certificates or write PEM encoded data.  It does, however,
+provide all of the tools required to build such functionality.  LibTomCrypt was designed to be a flexible library that 
+was not tied to any particular cryptographic problem.  
+
+\section{Why did I write it?}
+You may be wondering, ``Tom, why did you write a crypto library.  I already have one.''.  Well the reason falls into
+two categories:
+\begin{enumerate}
+    \item I am too lazy to figure out someone else's API.  I'd rather invent my own simpler API and use that.
+    \item It was (still is) good coding practice.
+\end{enumerate}
+
+The idea is that I am not striving to replace OpenSSL or Crypto++ or Cryptlib or etc.  I'm trying to write my 
+{\bf own} crypto library and hopefully along the way others will appreciate the work.
+
+With this library all core functions (ciphers, hashes, prngs) have the {\bf exact} same prototype definition.  They all load
+and store data in a format independent of the platform.  This means if you encrypt with Blowfish on a PPC it should decrypt
+on an x86 with zero problems.  The consistent API also means that if you learn how to use Blowfish with my library you 
+know how to use Safer+ or RC6 or Serpent or ... as well.  With all of the core functions there are central descriptor tables 
+that can be used to make a program automatically pick between ciphers, hashes and PRNGs at runtime.  That means your 
+application can support all ciphers/hashes/prngs without changing the source code.
+
+Not only did I strive to make a consistent and simple API to work with but I also strived to make the library
+configurable in terms of its build options.  Out of the box the library will build with any modern version of GCC
+without having to use configure scripts.  This means that the library will work with platforms where development
+tools may be limited (e.g. no autoconf).
+
+On top of making the build simple and the API approachable I've also strived for a reasonably high level of
+robustness and efficiency.  LibTomCrypt traps and returns a series of errors ranging from invalid
+arguments to buffer overflows/overruns.  It is mostly thread safe and has been clocked on various platforms
+with ``cycles per byte'' timings that are comparable (and often favourable) to other libraries such as OpenSSL and
+Crypto++.
+
+\subsection{Modular}
+The LibTomCrypt package has also been written to be very modular.  The block ciphers, one--way hashes and
+pseudo--random number generators (PRNG) are all used within the API through ``descriptor'' tables which 
+are essentially structures with pointers to functions.  While you can still call particular functions
+directly (\textit{e.g. sha256\_process()}) this descriptor interface allows the developer to customize their
+usage of the library.
+
+For example, consider a hardware platform with a specialized RNG device.  Obviously one would like to tap
+that for the PRNG needs within the library (\textit{e.g. making a RSA key}).  All the developer has to do
+is write a descriptor and the few support routines required for the device.  After that the rest of the 
+API can make use of it without change.  Similiarly imagine a few years down the road when AES2 
+(\textit{or whatever they call it}) has been invented.  It can be added to the library and used within applications 
+with zero modifications to the end applications provided they are written properly.
+
+This flexibility within the library means it can be used with any combination of primitive algorithms and 
+unlike libraries like OpenSSL is not tied to direct routines.  For instance, in OpenSSL there are CBC block
+mode routines for every single cipher.  That means every time you add or remove a cipher from the library
+you have to update the associated support code as well.  In LibTomCrypt the associated code (\textit{chaining modes in this case})
+are not directly tied to the ciphers.  That is a new cipher can be added to the library by simply providing 
+the key setup, ECB decrypt and encrypt and test vector routines.  After that all five chaining mode routines
+can make use of the cipher right away.
+
+\section{License}
+
+All of the source code except for the following files have been written by the author or donated to the project
+under a public domain license:
+
+\begin{enumerate}
+   \item rc2.c
+\end{enumerate}
+
+`mpi.c'' was originally written by Michael Fromberger (sting@linguist.dartmouth.edu) but has since been replaced with 
+my LibTomMath library which is public domain.
+
+``rc2.c'' is based on publicly available code that is not attributed to a person from the given source.  
+
+The project is hereby released as public domain.
+
+\section{Patent Disclosure}
+
+The author (Tom St Denis) is not a patent lawyer so this section is not to be treated as legal advice.  To the best
+of the authors knowledge the only patent related issues within the library are the RC5 and RC6 symmetric block ciphers.  
+They can be removed from a build by simply commenting out the two appropriate lines in ``tomcrypt\_custom.h''.  The rest
+of the ciphers and hashes are patent free or under patents that have since expired.
+
+The RC2 and RC4 symmetric ciphers are not under patents but are under trademark regulations.  This means you can use 
+the ciphers you just can't advertise that you are doing so.  
+

+\chapter{The Application Programming Interface (API)}
+\section{Introduction}
+\index{CRYPT\_ERROR} \index{CRYPT\_OK}
+
+In general the API is very simple to memorize and use.  Most of the functions return either {\bf void} or {\bf int}.  Functions
+that return {\bf int} will return {\bf CRYPT\_OK} if the function was successful or one of the many error codes 
+if it failed.  Certain functions that return int will return $-1$ to indicate an error.  These functions will be explicitly
+commented upon.  When a function does return a CRYPT error code it can be translated into a string with
+
+\index{error\_to\_string()}
+\begin{verbatim}
+const char *error_to_string(int err);
+\end{verbatim}
+
+An example of handling an error is:
+\begin{verbatim}
+void somefunc(void)
+{
+   int err;
+   
+   /* call a cryptographic function */
+   if ((err = some_crypto_function(...)) != CRYPT_OK) {
+      printf("A crypto error occured, %s\n", error_to_string(err));
+      /* perform error handling */
+   }
+   /* continue on if no error occured */
+}
+\end{verbatim}
+
+There is no initialization routine for the library and for the most part the code is thread safe.  The only thread
+related issue is if you use the same symmetric cipher, hash or public key state data in multiple threads.  Normally
+that is not an issue.
+
+To include the prototypes for ``LibTomCrypt.a'' into your own program simply include ``tomcrypt.h'' like so:
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void) {
+    return 0;
+}
+\end{verbatim}
+
+The header file ``tomcrypt.h'' also includes ``stdio.h'', ``string.h'', ``stdlib.h'', ``time.h'', ``ctype.h'' and 
+``ltc\_tommath.h'' (the bignum library routines).
+
+\section{Macros}
+
+There are a few helper macros to make the coding process a bit easier.  The first set are related to loading and storing
+32/64-bit words in little/big endian format.  The macros are:
+
+\index{STORE32L} \index{STORE64L} \index{LOAD32L} \index{LOAD64L} \index{STORE32H} \index{STORE64H} \index{LOAD32H} \index{LOAD64H} \index{BSWAP}
+\begin{small}
+\begin{center}
+\begin{tabular}{|c|c|c|}
+     \hline STORE32L(x, y) & {\bf unsigned long} x, {\bf unsigned char} *y & $x \to y[0 \ldots 3]$ \\
+     \hline STORE64L(x, y) & {\bf unsigned long long} x, {\bf unsigned char} *y & $x \to y[0 \ldots 7]$ \\
+     \hline LOAD32L(x, y) & {\bf unsigned long} x, {\bf unsigned char} *y & $y[0 \ldots 3] \to x$ \\
+     \hline LOAD64L(x, y) & {\bf unsigned long long} x, {\bf unsigned char} *y & $y[0 \ldots 7] \to x$ \\
+     \hline STORE32H(x, y) & {\bf unsigned long} x, {\bf unsigned char} *y & $x \to y[3 \ldots 0]$ \\
+     \hline STORE64H(x, y) & {\bf unsigned long long} x, {\bf unsigned char} *y & $x \to y[7 \ldots 0]$ \\
+     \hline LOAD32H(x, y) & {\bf unsigned long} x, {\bf unsigned char} *y & $y[3 \ldots 0] \to x$ \\
+     \hline LOAD64H(x, y) & {\bf unsigned long long} x, {\bf unsigned char} *y & $y[7 \ldots 0] \to x$ \\
+     \hline BSWAP(x) & {\bf unsigned long} x & Swaps byte order (32--bits only) \\
+     \hline
+\end{tabular}
+\end{center}
+\end{small}
+
+There are 32 and 64-bit cyclic rotations as well:
+\index{ROL} \index{ROR} \index{ROL64} \index{ROR64} \index{ROLc} \index{RORc} \index{ROL64c} \index{ROR64c} 
+\begin{center}
+\begin{tabular}{|c|c|c|}
+     \hline ROL(x, y) & {\bf unsigned long} x, {\bf unsigned long} y & $x << y, 0 \le y \le 31$ \\
+     \hline ROLc(x, y) & {\bf unsigned long} x, {\bf const unsigned long} y & $x << y, 0 \le y \le 31$ \\
+     \hline ROR(x, y) & {\bf unsigned long} x, {\bf unsigned long} y & $x >> y, 0 \le y \le 31$ \\
+     \hline RORc(x, y) & {\bf unsigned long} x, {\bf const unsigned long} y & $x >> y, 0 \le y \le 31$ \\
+     \hline && \\
+     \hline ROL64(x, y) & {\bf unsigned long} x, {\bf unsigned long} y & $x << y, 0 \le y \le 63$ \\
+     \hline ROL64c(x, y) & {\bf unsigned long} x, {\bf const unsigned long} y & $x << y, 0 \le y \le 63$ \\
+     \hline ROR64(x, y) & {\bf unsigned long} x, {\bf unsigned long} y & $x >> y, 0 \le y \le 63$ \\
+     \hline ROR64c(x, y) & {\bf unsigned long} x, {\bf const unsigned long} y & $x >> y, 0 \le y \le 63$ \\
+     \hline
+\end{tabular}
+\end{center}
+
+\section{Functions with Variable Length Output}
+Certain functions such as (for example) ``rsa\_export()'' give an output that is variable length.  To prevent buffer overflows you
+must pass it the length of the buffer\footnote{Extensive error checking is not in place but it will be in future releases so it is a good idea to follow through with these guidelines.} where
+the output will be stored.  For example:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void) {
+    rsa_key key;
+    unsigned char buffer[1024];
+    unsigned long x;
+    int err;
+
+    /* ... Make up the RSA key somehow ... */
+
+    /* lets export the key, set x to the size of the output buffer */
+    x = sizeof(buffer);
+    if ((err = rsa_export(buffer, &x, PK_PUBLIC, &key)) != CRYPT_OK) {
+       printf("Export error: %s\n", error_to_string(err));
+       return -1;
+    }
+    
+    /* if rsa_export() was successful then x will have the size of the output */
+    printf("RSA exported key takes %d bytes\n", x);
+
+    /* ... do something with the buffer */
+
+    return 0;
+}
+\end{verbatim}
+\end{small}
+In the above example if the size of the RSA public key was more than 1024 bytes this function would return an error code
+indicating a buffer overflow would have occurred.  If the function succeeds it stores the length of the output
+back into ``x'' so that the calling application will know how many bytes were used.
+
+\section{Functions that need a PRNG}
+\index{Pseudo Random Number Generator} \index{PRNG}
+Certain functions such as ``rsa\_make\_key()'' require a Pseudo Random Number Generator (PRNG).  These functions do not setup 
+the PRNG themselves so it is the responsibility of the calling function to initialize the PRNG before calling them.
+
+Certain PRNG algorithms do not require a ``prng\_state'' argument (sprng for example).  The ``prng\_state'' argument
+may be passed as \textbf{NULL} in such situations.
+
+\section{Functions that use Arrays of Octets}
+Most functions require inputs that are arrays of the data type ``unsigned char''.  Whether it is a symmetric key, IV
+for a chaining mode or public key packet it is assumed that regardless of the actual size of ``unsigned char'' only the
+lower eight bits contain data.  For example, if you want to pass a 256 bit key to a symmetric ciphers setup routine
+you must pass it in (a pointer to) an array of 32 ``unsigned char'' variables.  Certain routines 
+(such as SAFER+) take special care to work properly on platforms where an ``unsigned char'' is not eight bits.
+
+For the purposes of this library the term ``byte'' will refer to an octet or eight bit word.  Typically an array of
+type ``byte'' will be synonymous with an array of type ``unsigned char''.
+
+\chapter{Symmetric Block Ciphers}
+\section{Core Functions}
+
+LibTomCrypt provides several block ciphers with an ECB block mode interface.  It's important to first note that you 
+should never use the ECB modes directly to encrypt data.  Instead you should use the ECB functions to make a chaining mode
+or use one of the provided chaining modes.  All of the ciphers are written as ECB interfaces since it allows the rest of
+the API to grow in a modular fashion.
+
+\subsection{Key Scheduling}
+All ciphers store their scheduled keys in a single data type called ``symmetric\_key''.  This allows all ciphers to 
+have the same prototype and store their keys as naturally as possible.  This also removes the need for dynamic memory
+allocation and allows you to allocate a fixed sized buffer for storing scheduled keys.  All ciphers provide five visible 
+functions which are (given that XXX is the name of the cipher):
+\index{Cipher Setup}
+\begin{verbatim}
+int XXX_setup(const unsigned char *key, int keylen, int rounds,
+              symmetric_key *skey);
+\end{verbatim}
+
+The XXX\_setup() routine will setup the cipher to be used with a given number of rounds and a given key length (in bytes).
+The number of rounds can be set to zero to use the default, which is generally a good idea.
+
+If the function returns successfully the variable ``skey'' will have a scheduled key stored in it.  It's important to note
+that you should only used this scheduled key with the intended cipher.  For example, if you call ``blowfish\_setup()'' do not 
+pass the scheduled key onto ``rc5\_ecb\_encrypt()''.  All setup functions do not allocate memory off the heap so when you are 
+done with a key you can simply discard it (e.g. they can be on the stack).
+
+\subsection{ECB Encryption and Decryption}
+To encrypt or decrypt a block in ECB mode there are these two function classes
+\index{Cipher Encrypt} \index{Cipher Decrypt}
+\begin{verbatim}
+void XXX_ecb_encrypt(const unsigned char *pt, unsigned char *ct,
+                     symmetric_key *skey);
+
+void XXX_ecb_decrypt(const unsigned char *ct, unsigned char *pt,
+                     symmetric_key *skey);
+\end{verbatim}
+These two functions will encrypt or decrypt (respectively) a single block of text\footnote{The size of which depends on
+which cipher you are using.} and store the result where you want it.  It is possible that the input and output buffer are 
+the same buffer.  For the encrypt function ``pt''\footnote{pt stands for plaintext.} is the input and 
+``ct''\footnote{ct stands for ciphertext.} is the output.  For the decryption function it's the opposite.  To test a particular 
+cipher against test vectors\footnote{As published in their design papers.} call the self-test function
+ 
+\subsection{Self--Testing}
+\index{Cipher Testing}
+\begin{verbatim}
+int XXX_test(void);
+\end{verbatim}
+This function will return {\bf CRYPT\_OK} if the cipher matches the test vectors from the design publication it is 
+based upon.  
+
+\subsection{Key Sizing}
+For each cipher there is a function which will help find a desired key size:
+\begin{verbatim}
+int XXX_keysize(int *keysize);
+\end{verbatim}
+Essentially it will round the input keysize in ``keysize'' down to the next appropriate key size.  This function
+return {\bf CRYPT\_OK} if the key size specified is acceptable.  For example:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int keysize, err;
+
+   /* now given a 20 byte key what keysize does Twofish want to use? */
+   keysize = 20;
+   if ((err = twofish_keysize(&keysize)) != CRYPT_OK) {
+      printf("Error getting key size: %s\n", error_to_string(err));
+      return -1;
+   }
+   printf("Twofish suggested a key size of %d\n", keysize);
+   return 0;
+}
+\end{verbatim}
+\end{small}
+This should indicate a keysize of sixteen bytes is suggested.  
+
+\subsection{Cipher Termination}
+When you are finished with a cipher you can de--initialize it with the done function.
+\begin{verbatim}
+void XXX_done(symmetric_key *skey);
+\end{verbatim}
+For the software based ciphers within LibTomCrypt this function will not do anything.  However, user supplied
+cipher descriptors may require calls to it for resource management.  To be compliant all functions which call a cipher
+setup function must also call the respective cipher done function when finished.
+
+\subsection{Simple Encryption Demonstration}
+An example snippet that encodes a block with Blowfish in ECB mode is below.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{ 
+   unsigned char pt[8], ct[8], key[8];
+   symmetric_key skey;
+   int err;
+
+   /* ... key is loaded appropriately in ``key'' ... */
+   /* ... load a block of plaintext in ``pt'' ... */
+
+   /* schedule the key */
+   if ((err = blowfish_setup(key,     /* the key we will use */

+\section{Key Sizes and Number of Rounds}
+\index{Symmetric Keys}
+As a general rule of thumb do not use symmetric keys under 80 bits if you can.  Only a few of the ciphers support smaller
+keys (mainly for test vectors anyways).  Ideally your application should be making at least 256 bit keys.  This is not
+because you're supposed to be paranoid.  It's because if your PRNG has a bias of any sort the more bits the better.  For
+example, if you have $\mbox{Pr}\left[X = 1\right] = {1 \over 2} \pm \gamma$ where $\vert \gamma \vert > 0$ then the
+total amount of entropy in N bits is $N \cdot -log_2\left ({1 \over 2} + \vert \gamma \vert \right)$.  So if $\gamma$
+were $0.25$ (a severe bias) a 256-bit string would have about 106 bits of entropy whereas a 128-bit string would have
+only 53 bits of entropy.
+
+The number of rounds of most ciphers is not an option you can change.  Only RC5 allows you to change the number of
+rounds.  By passing zero as the number of rounds all ciphers will use their default number of rounds.  Generally the
+ciphers are configured such that the default number of rounds provide adequate security for the given block and key 
+size.
+

+Where ``name'' is the lower case ASCII version of the name.  The fields ``min\_key\_length'' and ``max\_key\_length'' 
+are the minimum and maximum key sizes in bytes.  The ``block\_length'' member is the block size of the cipher
+in bytes.  As a good rule of thumb it is assumed that the cipher supports

+\subsection{Notes}
+\begin{small}
+\begin{enumerate}
+\item
+For AES (also known as Rijndael) there are four descriptors which complicate issues a little.  The descriptors 
+rijndael\_desc and rijndael\_enc\_desc provide the cipher named ``rijndael''.  The descriptors aes\_desc and 
+aes\_enc\_desc provide the cipher name ``aes''.  Functionally both ``rijndael'' and ``aes'' are the same cipher.  The
+only difference is when you call find\_cipher() you have to pass the correct name.  The cipher descriptors with ``enc'' 
+in the middle (e.g. rijndael\_enc\_desc) are related to an implementation of Rijndael with only the encryption routine
+and tables.  The decryption and self--test function pointers of both ``encrypt only'' descriptors are set to \textbf{NULL} and 
+should not be called.
+
+The ``encrypt only'' descriptors are useful for applications that only use the encryption function of the cipher.  Algorithms such
+as EAX, PMAC and OMAC only require the encryption function.  So far this ``encrypt only'' functionality has only been implemented for
+Rijndael as it makes the most sense for this cipher.
+
+\item
+Note that for ``DES'' and ``3DES'' they use 8 and 24 byte keys but only 7 and 21 [respectively] bytes of the keys are in
+fact used for the purposes of encryption.  My suggestion is just to use random 8/24 byte keys instead of trying to make a 8/24
+byte string from the real 7/21 byte key.
+
+\item
+Note that ``Twofish'' has additional configuration options that take place at build time.  These options are found in
+the file ``tomcrypt\_cfg.h''.  The first option is ``TWOFISH\_SMALL'' which when defined will force the Twofish code
+to not pre-compute the Twofish ``$g(X)$'' function as a set of four $8 \times 32$ s-boxes.  This means that a scheduled
+key will require less ram but the resulting cipher will be slower.  The second option is ``TWOFISH\_TABLES'' which when
+defined will force the Twofish code to use pre-computed tables for the two s-boxes $q_0, q_1$ as well as the multiplication
+by the polynomials 5B and EF used in the MDS multiplication.  As a result the code is faster and slightly larger.  The
+speed increase is useful when ``TWOFISH\_SMALL'' is defined since the s-boxes and MDS multiply form the heart of the
+Twofish round function.
+

+\end{enumerate}
+\end{small}
+
+To work with the cipher\_descriptor array there is a function:
+\index{find\_cipher()}
+\begin{verbatim}
+int find_cipher(char *name)
+\end{verbatim}
+Which will search for a given name in the array.  It returns negative one if the cipher is not found, otherwise it returns
+the location in the array where the cipher was found.  For example, to indirectly setup Blowfish you can also use:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   unsigned char key[8];
+   symmetric_key skey;
+   int err;
+
+   /* you must register a cipher before you use it */
+   if (register_cipher(&blowfish_desc)) == -1) {
+      printf("Unable to register Blowfish cipher.");
+      return -1;
+   }
+
+   /* generic call to function (assuming the key in key[] was already setup) */
+   if ((err = cipher_descriptor[find_cipher("blowfish")].setup(key, 8, 0, &skey)) != 
+       CRYPT_OK) {
+      printf("Error setting up Blowfish: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* ... use cipher ... */
+}
+\end{verbatim}
+\end{small}
+
+A good safety would be to check the return value of ``find\_cipher()'' before accessing the desired function.  In order
+to use a cipher with the descriptor table you must register it first using:
+\index{register\_cipher()}
+\begin{verbatim}
+int register_cipher(const struct _cipher_descriptor *cipher);
+\end{verbatim}
+Which accepts a pointer to a descriptor and returns the index into the global descriptor table.  If an error occurs such
+as there is no more room (it can have 32 ciphers at most) it will return {\bf{-1}}.  If you try to add the same cipher more
+than once it will just return the index of the first copy.  To remove a cipher call:
+\index{unregister\_cipher()}
+\begin{verbatim}
+int unregister_cipher(const struct _cipher_descriptor *cipher);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if it removes it otherwise it returns {\bf CRYPT\_ERROR}.  Consider:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int err;
+   
+   /* register the cipher */
+   if (register_cipher(&rijndael_desc) == -1) {
+      printf("Error registering Rijndael\n");
+      return -1;
+   }
+
+   /* use Rijndael */
+
+   /* remove it */
+   if ((err = unregister_cipher(&rijndael_desc)) != CRYPT_OK) {
+      printf("Error removing Rijndael: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   return 0;
+}
+\end{verbatim}
+\end{small}
+This snippet is a small program that registers only Rijndael only.  
+
+\section{Symmetric Modes of Operations}
+\subsection{Background}
+A typical symmetric block cipher can be used in chaining modes to effectively encrypt messages larger than the block
+size of the cipher.  Given a key $k$, a plaintext $P$ and a cipher $E$ we shall denote the encryption of the block
+$P$ under the key $k$ as $E_k(P)$.  In some modes there exists an initial vector denoted as $C_{-1}$.
+
+\subsubsection{ECB Mode}
+\index{ECB mode}
+ECB or Electronic Codebook Mode is the simplest method to use.  It is given as:
+\begin{equation}
+C_i = E_k(P_i)
+\end{equation}
+This mode is very weak since it allows people to swap blocks and perform replay attacks if the same key is used more
+than once.
+
+\subsubsection{CBC Mode}
+\index{CBC mode}
+CBC or Cipher Block Chaining mode is a simple mode designed to prevent trivial forms of replay and swap attacks on ciphers.
+It is given as:
+\begin{equation}
+C_i = E_k(P_i \oplus C_{i - 1})
+\end{equation}
+It is important that the initial vector be unique and preferably random for each message encrypted under the same key.
+
+\subsubsection{CTR Mode}
+\index{CTR mode}
+CTR or Counter Mode is a mode which only uses the encryption function of the cipher.  Given a initial vector which is
+treated as a large binary counter the CTR mode is given as:
+\begin{eqnarray}
+C_{-1} = C_{-1} + 1\mbox{ }(\mbox{mod }2^W) \nonumber \\
+C_i = P_i \oplus E_k(C_{-1})
+\end{eqnarray}
+Where $W$ is the size of a block in bits (e.g. 64 for Blowfish).  As long as the initial vector is random for each message
+encrypted under the same key replay and swap attacks are infeasible.  CTR mode may look simple but it is as secure
+as the block cipher is under a chosen plaintext attack (provided the initial vector is unique).
+
+\subsubsection{CFB Mode}
+\index{CFB mode}
+CFB or Ciphertext Feedback Mode is a mode akin to CBC.  It is given as:
+\begin{eqnarray}
+C_i = P_i \oplus C_{-1} \nonumber \\
+C_{-1} = E_k(C_i)
+\end{eqnarray}
+Note that in this library the output feedback width is equal to the size of the block cipher.  That is this mode is used
+to encrypt whole blocks at a time.  However, the library will buffer data allowing the user to encrypt or decrypt partial
+blocks without a delay.  When this mode is first setup it will initially encrypt the initial vector as required.
+
+\subsubsection{OFB Mode}
+\index{OFB mode}
+OFB or Output Feedback Mode is a mode akin to CBC as well.  It is given as:
+\begin{eqnarray}
+C_{-1} = E_k(C_{-1}) \nonumber \\
+C_i = P_i \oplus C_{-1}
+\end{eqnarray}
+Like the CFB mode the output width in CFB mode is the same as the width of the block cipher.  OFB mode will also
+buffer the output which will allow you to encrypt or decrypt partial blocks without delay.
+
+\subsection{Choice of Mode}
+My personal preference is for the CTR mode since it has several key benefits:
+\begin{enumerate}
+   \item No short cycles which is possible in the OFB and CFB modes.
+   \item Provably as secure as the block cipher being used under a chosen plaintext attack.
+   \item Technically does not require the decryption routine of the cipher.
+   \item Allows random access to the plaintext.
+   \item Allows the encryption of block sizes that are not equal to the size of the block cipher.
+\end{enumerate}
+The CTR, CFB and OFB routines provided allow you to encrypt block sizes that differ from the ciphers block size.  They 
+accomplish this by buffering the data required to complete a block.  This allows you to encrypt or decrypt any size 
+block of memory with either of the three modes.
+
+The ECB and CBC modes process blocks of the same size as the cipher at a time.  Therefore they are less flexible than the
+other modes.
+
+\subsection{Initialization}
+\index{CBC Mode} \index{CTR Mode}
+\index{OFB Mode} \index{CFB Mode}
+The library provides simple support routines for handling CBC, CTR, CFB, OFB and ECB encoded messages.  Assuming the mode 
+you want is XXX there is a structure called ``symmetric\_XXX'' that will contain the information required to
+use that mode.  They have identical setup routines (except CTR and ECB mode):
+\index{ecb\_start()} \index{cfb\_start()} \index{cbc\_start()} \index{ofb\_start()} \index{ctr\_start()}
+\begin{verbatim}
+int XXX_start(int cipher, const unsigned char *IV, 
+              const unsigned char *key, int keylen, 
+              int num_rounds, symmetric_XXX *XXX);
+
+int ctr_start(               int   cipher,
+              const unsigned char *IV,
+              const unsigned char *key,       int keylen,
+                             int  num_rounds, int ctr_mode,
+                   symmetric_CTR *ctr);
+
+int ecb_start(int cipher, const unsigned char *key, int keylen, 
+              int num_rounds, symmetric_ECB *ecb);
+\end{verbatim}
+
+In each case ``cipher'' is the index into the cipher\_descriptor array of the cipher you want to use.  The ``IV'' value is 
+the initialization vector to be used with the cipher.  You must fill the IV yourself and it is assumed they are the same 
+length as the block size\footnote{In otherwords the size of a block of plaintext for the cipher, e.g. 8 for DES, 16 for AES, etc.} 
+of the cipher you choose.  It is important that the IV  be random for each unique message you want to encrypt.  The 
+parameters ``key'', ``keylen'' and ``num\_rounds'' are the same as in the XXX\_setup() function call.  The final parameter 
+is a pointer to the structure you want to hold the information for the mode of operation.
+
+
+In the case of CTR mode there is an additional parameter ``ctr\_mode'' which specifies the mode that the counter is to be used in.
+If \textbf{CTR\_COUNTER\_LITTLE\_ENDIAN} was specified then the counter will be treated as a little endian value.  Otherwise, if 
+\textbf{CTR\_COUNTER\_BIG\_ENDIAN} was specified the counter will be treated as a big endian value.
+
+The routines return {\bf CRYPT\_OK} if the cipher initialized correctly, otherwise they return an error code.  
+
+\subsection{Encryption and Decryption}
+To actually encrypt or decrypt the following routines are provided:
+\index{ecb\_encrypt()} \index{ecb\_decrypt()} \index{cfb\_encrypt()} \index{cfb\_decrypt()} 
+\index{cbc\_encrypt()} \index{cbc\_decrypt()} \index{ofb\_encrypt()} \index{ofb\_decrypt()} \index{ctr\_encrypt()} \index{ctr\_decrypt()}
+\begin{verbatim}
+int XXX_encrypt(const unsigned char *pt, unsigned char *ct, 
+                unsigned long len, symmetric_YYY *YYY);
+int XXX_decrypt(const unsigned char *ct, unsigned char *pt, 
+                unsigned long len, symmetric_YYY *YYY);
+\end{verbatim}
+Where ``XXX'' is one of $\lbrace ecb, cbc, ctr, cfb, ofb \rbrace$.  
+
+In all cases ``len'' is the size of the buffer (as number of octets) to encrypt or decrypt.  The CTR, OFB and CFB modes are order sensitive but not
+chunk sensitive.  That is you can encrypt ``ABCDEF'' in three calls like ``AB'', ``CD'', ``EF'' or two like ``ABCDE'' and ``F''
+and end up with the same ciphertext.  However, encrypting ``ABC'' and ``DABC'' will result in different ciphertexts.  All
+five of the modes will return {\bf CRYPT\_OK} on success from the encrypt or decrypt functions.
+
+In the ECB and CBC cases ``len'' must be a multiple of the ciphers block size.  In the CBC case you must manually pad the end of your message (either with
+zeroes or with whatever your protocol requires).
+
+To decrypt in either mode you simply perform the setup like before (recall you have to fetch the IV value you used)
+and use the decrypt routine on all of the blocks.
+
+\subsection{IV Manipulation}
+To change or read the IV of a previously initialized chaining mode use the following two functions.
+
+\index{cbc\_setiv()} \index{cbc\_getiv()} \index{ofb\_setiv()} \index{ofb\_getiv()} \index{cfb\_setiv()} \index{cfb\_getiv()}
+\index{ctr\_setiv()} \index{ctr\_getiv()}
+\begin{verbatim}
+int XXX_getiv(unsigned char *IV, unsigned long *len, symmetric_XXX *XXX);
+int XXX_setiv(const unsigned char *IV, unsigned long len, symmetric_XXX *XXX);
+\end{verbatim}
+
+The XXX\_getiv() functions will read the IV out of the chaining mode and store it into ``IV'' along with the length of the IV 
+stored in ``len''.  The XXX\_setiv will initialize the chaining mode state as if the original IV were the new IV specified.  The length
+of the IV passed in must be the size of the ciphers block size.
+
+The XXX\_setiv() functions are handy if you wish to change the IV without re--keying the cipher.  
+
+\subsection{Stream Termination}
+To terminate an open stream call the done function.
+
+\index{ecb\_done()} \index{cbc\_done()}\index{cfb\_done()}\index{ofb\_done()} \index{ctr\_done()}
+\begin{verbatim}
+int XXX_done(symmetric_XXX *XXX);
+\end{verbatim}
+
+This will terminate the stream (by terminating the cipher) and return \textbf{CRYPT\_OK} if successful.
+
+\subsection{Examples}

+\section{Encrypt and Authenticate Modes}
+
+\subsection{EAX Mode}
+LibTomCrypt provides support for a mode called EAX\footnote{See 
+M. Bellare, P. Rogaway, D. Wagner, A Conventional Authenticated-Encryption Mode.} in a manner similar to the
+way it was intended to be used by the designers.  First a short description of what EAX mode is before I explain how to use it.  
+EAX is a mode that requires a cipher, CTR and OMAC support and provides encryption and authentication\footnote{Note that since EAX only requires OMAC and CTR you may use ``encrypt only'' cipher descriptors with this mode.}.  
+It is initialized with a random ``nonce'' that can be shared publicly as well as a ``header'' which can be fixed and public as well as a random 
+secret symmetric key.
+
+The ``header'' data is meant to be meta-data associated with a stream that isn't private (e.g. protocol messages).  It can
+be added at anytime during an EAX stream and is part of the authentication tag.  That is, changes in the meta-data can
+be detected by changes in the output tag.
+
+The mode can then process plaintext producing ciphertext as well as compute a partial checksum.  The actual checksum
+called a ``tag'' is only emitted when the message is finished.  In the interim though the user can process any arbitrary
+sized message block to send to the recipient as ciphertext.  This makes the EAX mode especially suited for streaming modes
+of operation.
+
+The mode is initialized with the following function.
+\index{eax\_init()}
+\begin{verbatim}
+int eax_init(eax_state *eax, int cipher, 
+             const unsigned char *key, unsigned long keylen,
+             const unsigned char *nonce, unsigned long noncelen,
+             const unsigned char *header, unsigned long headerlen);
+\end{verbatim}
+
+Where ``eax'' is the EAX state.  ``cipher'' is the index of the desired cipher in the descriptor table.  
+``key'' is the shared secret symmetric key of length ``keylen''.  ``nonce'' is the random public string of
+length ``noncelen''.  ``header'' is the random (or fixed or \textbf{NULL}) header for the message of length
+``headerlen''.
+
+When this function completes ``eax'' will be initialized such that you can now either have data decrypted or 
+encrypted in EAX mode.  Note that if ``headerlen'' is zero you may pass ``header'' as \textbf{NULL} to indicate
+there is no initial header data.
+
+To encrypt or decrypt data in a streaming mode use the following.
+\index{eax\_encrypt()} \index{eax\_decrypt()}
+\begin{verbatim}
+int eax_encrypt(eax_state *eax, const unsigned char *pt, 
+                unsigned char *ct, unsigned long length);
+
+int eax_decrypt(eax_state *eax, const unsigned char *ct, 
+                unsigned char *pt, unsigned long length);
+\end{verbatim}
+The function ``eax\_encrypt'' will encrypt the bytes in ``pt'' of ``length'' bytes and store the ciphertext in
+``ct''.  Note that ``ct'' and ``pt'' may be the same region in memory.   This function will also send the ciphertext
+through the OMAC function.  The function ``eax\_decrypt'' decrypts ``ct'' and stores it in ``pt''.  This also allows 
+``pt'' and ``ct'' to be the same region in memory.  
+
+You cannot both encrypt or decrypt with the same ``eax'' context.  For bi-directional communication you
+will need to initialize two EAX contexts (preferably with different headers and nonces).  
+
+Note that both of these functions allow you to send the data in any granularity but the order is important.  While
+the eax\_init() function allows you to add initial header data to the stream you can also add header data during the
+EAX stream with the following.
+
+\index{eax\_addheader()}
+\begin{verbatim}
+int eax_addheader(eax_state *eax, 
+                  const unsigned char *header, unsigned long length);
+\end{verbatim}
+
+This will add the ``length'' bytes from ``header'' to the given ``eax'' stream.  Once the message is finished the 
+``tag'' (checksum) may be computed with the following function.
+
+\index{eax\_done()}
+\begin{verbatim}
+int eax_done(eax_state *eax, 
+             unsigned char *tag, unsigned long *taglen);
+\end{verbatim}
+This will terminate the EAX state ``eax'' and store upto ``taglen'' bytes of the message tag in ``tag''.  The function
+then stores how many bytes of the tag were written out back into ``taglen''.
+
+The EAX mode code can be tested to ensure it matches the test vectors by calling the following function.
+\index{eax\_test()}
+\begin{verbatim}
+int eax_test(void);
+\end{verbatim}
+This requires that the AES (or Rijndael) block cipher be registered with the cipher\_descriptor table first.
+
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int           err;
+   eax_state     eax;
+   unsigned char pt[64], ct[64], nonce[16], key[16], tag[16];
+   unsigned long taglen;
+
+   if (register_cipher(&rijndael_desc) == -1) {
+      printf("Error registering Rijndael");
+      return EXIT_FAILURE;
+   }
+
+   /* ... make up random nonce and key ... */
+
+   /* initialize context */
+   if ((err = eax_init(            &eax,  /* the context */
+                find_cipher("rijndael"),  /* cipher we want to use */
+                                  nonce,  /* our state nonce */
+                                     16,  /* none is 16 bytes */
+                              "TestApp",  /* example header, identifies this program */
+                                      7)  /* length of the header */
+       ) != CRYPT_OK) {
+      printf("Error eax_init: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* now encrypt data, say in a loop or whatever */
+   if ((err = eax_encrypt(     &eax,      /* eax context */
+                                 pt,      /* plaintext  (source) */
+                                 ct,      /* ciphertext (destination) */
+                          sizeof(pt)      /* size of plaintext */
+      ) != CRYPT_OK) {
+      printf("Error eax_encrypt: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* finish message and get authentication tag */
+   taglen = sizeof(tag);
+   if ((err = eax_done(   &eax,           /* eax context */
+                           tag,           /* where to put tag */
+                       &taglen            /* length of tag space */
+      ) != CRYPT_OK) {
+      printf("Error eax_done: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* now we have the authentication tag in "tag" and it's taglen bytes long */
+
+}
+\end{verbatim}
+                       
+You can also perform an entire EAX state on a block of memory in a single function call with the 
+following functions.
+
+
+\index{eax\_encrypt\_authenticate\_memory} \index{eax\_decrypt\_verify\_memory}
+\begin{verbatim}
+int eax_encrypt_authenticate_memory(int cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  unsigned long noncelen,
+    const unsigned char *header, unsigned long headerlen,
+    const unsigned char *pt,     unsigned long ptlen,
+          unsigned char *ct,
+          unsigned char *tag,    unsigned long *taglen);
+
+int eax_decrypt_verify_memory(int cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  unsigned long noncelen,
+    const unsigned char *header, unsigned long headerlen,
+    const unsigned char *ct,     unsigned long ctlen,
+          unsigned char *pt,
+          unsigned char *tag,    unsigned long taglen,
+          int           *res);
+\end{verbatim}
+
+Both essentially just call eax\_init() followed by eax\_encrypt() (or eax\_decrypt() respectively) and eax\_done().  The parameters
+have the same meaning as with those respective functions.  
+
+The only difference is eax\_decrypt\_verify\_memory() does not emit a tag.  Instead you pass it a tag as input and it compares it against
+the tag it computed while decrypting the message.  If the tags match then it stores a $1$ in ``res'', otherwise it stores a $0$.
+
+\subsection{OCB Mode}
+LibTomCrypt provides support for a mode called OCB\footnote{See 
+P. Rogaway, M. Bellare, J. Black, T. Krovetz, ``OCB: A Block Cipher Mode of Operation for Efficient Authenticated Encryption''.}
+.  OCB is an encryption protocol that simultaneously provides authentication.  It is slightly faster to use than EAX mode
+but is less flexible.  Let's review how to initialize an OCB context.
+
+\index{ocb\_init()}
+\begin{verbatim}
+int ocb_init(ocb_state *ocb, int cipher, 
+             const unsigned char *key, unsigned long keylen, 
+             const unsigned char *nonce);
+\end{verbatim}
+
+This will initialize the ``ocb'' context using cipher descriptor ``cipher''.  It will use a ``key'' of length ``keylen''
+and the random ``nonce''.  Note that ``nonce'' must be a random (public) string the same length as the block ciphers
+block size (e.g. 16 bytes for AES).
+
+This mode has no ``Associated Data'' like EAX mode does which means you cannot authenticate metadata along with the stream.
+To encrypt or decrypt data use the following.
+
+\index{ocb\_encrypt()} \index{ocb\_decrypt()}
+\begin{verbatim}
+int ocb_encrypt(ocb_state *ocb, const unsigned char *pt, unsigned char *ct);
+int ocb_decrypt(ocb_state *ocb, const unsigned char *ct, unsigned char *pt);
+\end{verbatim}
+
+This will encrypt (or decrypt for the latter) a fixed length of data from ``pt'' to ``ct'' (vice versa for the latter).  
+They assume that ``pt'' and ``ct'' are the same size as the block cipher's block size.  Note that you cannot call 
+both functions given a single ``ocb'' state.  For bi-directional communication you will have to initialize two ``ocb''
+states (with different nonces).  Also ``pt'' and ``ct'' may point to the same location in memory.
+
+\subsubsection{State Termination}
+
+When you are finished encrypting the message you call the following function to compute the tag.
+
+\index{ocb\_done\_encrypt()}
+\begin{verbatim}
+int ocb_done_encrypt(ocb_state *ocb, 
+                     const unsigned char *pt, unsigned long ptlen,
+                           unsigned char *ct, 
+                           unsigned char *tag, unsigned long *taglen);
+\end{verbatim}
+
+This will terminate an encrypt stream ``ocb''.  If you have trailing bytes of plaintext that will not complete a block 
+you can pass them here.  This will also encrypt the ``ptlen'' bytes in ``pt'' and store them in ``ct''.  It will also
+store upto ``taglen'' bytes of the tag into ``tag''.
+
+Note that ``ptlen'' must be less than or equal to the block size of block cipher chosen.  Also note that if you have 
+an input message equal to the length of the block size then you pass the data here (not to ocb\_encrypt()) only.  
+
+To terminate a decrypt stream and compared the tag you call the following.
+
+\index{ocb\_done\_decrypt()}
+\begin{verbatim}
+int ocb_done_decrypt(ocb_state *ocb, 
+                     const unsigned char *ct,  unsigned long ctlen,
+                           unsigned char *pt, 
+                     const unsigned char *tag, unsigned long taglen, 
+                           int *res);
+\end{verbatim}
+
+Similarly to the previous function you can pass trailing message bytes into this function.  This will compute the 
+tag of the message (internally) and then compare it against the ``taglen'' bytes of ``tag'' provided.  By default
+``res'' is set to zero.  If all ``taglen'' bytes of ``tag'' can be verified then ``res'' is set to one (authenticated
+message).
+
+\subsubsection{Packet Functions}
+To make life simpler the following two functions are provided for memory bound OCB.
+
+\index{ocb\_encrypt\_authenticate\_memory()}
+\begin{verbatim}
+int ocb_encrypt_authenticate_memory(int cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  
+    const unsigned char *pt,     unsigned long ptlen,
+          unsigned char *ct,
+          unsigned char *tag,    unsigned long *taglen);
+\end{verbatim}
+
+This will OCB encrypt the message ``pt'' of length ``ptlen'' and store the ciphertext in ``ct''.  The length ``ptlen''
+can be any arbitrary length.  
+
+\index{ocb\_decrypt\_verify\_memory()}
+\begin{verbatim}
+int ocb_decrypt_verify_memory(int cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  
+    const unsigned char *ct,     unsigned long ctlen,
+          unsigned char *pt,
+    const unsigned char *tag,    unsigned long taglen,
+          int           *res);
+\end{verbatim}
+
+Similarly this will OCB decrypt and compare the internally computed tag against the tag provided. ``res'' is set 
+appropriately.
+
+\subsection{CCM Mode}
+CCM is a NIST proposal for Encrypt+Authenticate that is centered around using AES (or any 16--byte cipher) as a primitive.  Unlike EAX and OCB mode
+it is only meant for ``packet'' mode where the length of the input is known in advance.  Since it is a packet mode function CCM only has one 
+function that performs the protocol.
+
+\index{ccm\_memory()}
+\begin{verbatim}
+int ccm_memory(int cipher,
+    const unsigned char *key,    unsigned long keylen,
+    const unsigned char *nonce,  unsigned long noncelen,
+    const unsigned char *header, unsigned long headerlen,
+          unsigned char *pt,     unsigned long ptlen,
+          unsigned char *ct,
+          unsigned char *tag,    unsigned long *taglen,
+                    int  direction);
+\end{verbatim}
+
+This performs the ``CCM'' operation on the data.  The ``cipher'' variable indicates which cipher in the descriptor table to use.  It must have a 
+16--byte block size for CCM.  The key is ``key'' with a length of ``keylen'' octets.  The nonce or salt is ``nonce'' of
+length ``noncelen'' octets.  The header is meta--data you want to send with the message but not have encrypted, it is stored in ``header''
+of length ``headerlen'' octets.  The header can be zero octets long (if $headerlen = 0$ then you can pass ``header'' as \textbf{NULL}).  
+
+The plaintext is stored in ``pt'' and the ciphertext in ``ct''.  The length of both are expected to be equal and is passed in as ``ptlen''.  It is
+allowable that $pt = ct$.  The ``direction'' variable indicates whether encryption (direction $=$ \textbf{CCM\_ENCRYPT}) or 
+decryption (direction $=$ \textbf{CCM\_DECRYPT}) is to be performed.
+
+As implemented this copy of CCM cannot handle a header or plaintext longer than $2^{32} - 1$ octets long.  
+
+You can test the implementation of CCM with the following function.
+
+\index{ccm\_test()}
+\begin{verbatim}
+int ccm_test(void);
+\end{verbatim}
+
+This will return \textbf{CRYPT\_OK} if the CCM routine passes known test vectors.
+
+\subsection{GCM Mode}
+Galois counter mode is an IEEE proposal for authenticated encryption.  Like EAX and OCB it can be used in a streaming capacity however, unlike EAX it cannot
+accept ``additional authentication data'' (meta--data) after plaintext has been processed.  This mode also only works with block ciphers with a sixteen
+byte block.
+
+A GCM stream is meant to be processed in three modes each one sequential serial.  First the initial vector (per session) data is processed.  This should be 
+unique to every session.  Next the the optional additional authentication data is processed and finally the plaintext.  
+
+\subsubsection{Initialization}
+To initialize the GCM context with a secret key call the following function.
+
+\index{gcm\_init()}
+\begin{verbatim}
+int gcm_init(gcm_state *gcm, int cipher,
+             const unsigned char *key, int keylen);
+\end{verbatim}
+This initializes the GCM state ``gcm'' for the given cipher indexed by ``cipher'' with a secret key ``key'' of length ``keylen'' octets.  The cipher chosen
+must have a 16--byte block size (e.g. AES).  
+
+\subsubsection{Initial Vector}
+After the state has been initialized (or reset) the next step is to add the session (or packet) initial vector.  It should be unique per packet encrypted.
+
+\index{gcm\_add\_iv()}
+\begin{verbatim}
+int gcm_add_iv(gcm_state *gcm, 
+               const unsigned char *IV,     unsigned long IVlen);
+\end{verbatim}
+
+This adds the initial vector octets from ``IV'' of length ``IVlen'' to the GCM state ``gcm''.  You can call this function as many times as required
+to process the entire IV.  
+
+Note that the GCM protocols provides a ``shortcut'' for 12--byte IVs where no preprocessing is to be done.  If you want to minimize per packet latency it's ideal
+to only use 12--byte IVs.  You can just increment it like a counter for each packet and the CTR [privacy] will be ensured.
+
+\subsubsection{Additional Authentication Data}
+After the entire IV has been processed the additional authentication data can be processed.  Unlike the IV a packet/session does not require additional
+authentication data (AAD) for security.  The AAD is meant to be used as side--channel data you want to be authenticated with the packet.  Note that once
+you begin adding AAD to the GCM state you cannot return to adding IV data until the state is reset.
+
+\index{gcm\_add\_aad()}
+\begin{verbatim}
+int gcm_add_aad(gcm_state *gcm, 
+               const unsigned char *adata,     unsigned long adatalen);
+\end{verbatim}
+This adds the additional authentication data ``adata'' of length ``adatalen'' to the GCM state ``gcm''.
+
+\subsubsection{Plaintext Processing}
+After the AAD has been processed the plaintext (or ciphertext depending on the direction) can be processed.  
+
+\index{gcm\_process()}
+\begin{verbatim}
+int gcm_process(gcm_state *gcm,
+                     unsigned char *pt,     unsigned long ptlen,
+                     unsigned char *ct,
+                     int direction);
+\end{verbatim}
+This processes message data where ``pt'' is the plaintext and ``ct'' is the ciphertext.  The length of both are equal and stored in ``ptlen''.  Depending on the 
+mode ``pt'' is the input and ``ct'' is the output (or vice versa).  When ``direction'' equals \textbf{GCM\_ENCRYPT} the plaintext is read, encrypted and stored
+in the ciphertext buffer.  When ``direction'' equals \textbf{GCM\_DECRYPT} the opposite occurs.
+
+\subsubsection{State Termination}
+To terminate a GCM state and retrieve the message authentication tag call the following function.
+
+\index{gcm\_done()}
+\begin{verbatim}
+int gcm_done(gcm_state *gcm, 
+                     unsigned char *tag,    unsigned long *taglen);
+\end{verbatim}
+This terminates the GCM state ``gcm'' and stores the tag in ``tag'' of length ``taglen'' octets.
+
+\subsubsection{State Reset}
+The call to gcm\_init() will perform considerable pre--computation (when \textbf{GCM\_TABLES} is defined) and if you're going to be dealing with a lot of packets
+it is very costly to have to call it repeatedly.  To aid in this endeavour the reset function has been provided.
+
+\index{gcm\_reset()}
+\begin{verbatim}
+int gcm_reset(gcm_state *gcm);
+\end{verbatim}
+
+This will reset the GCM state ``gcm'' to the state that gcm\_init() left it.  The user would then call gcm\_add\_iv(), gcm\_add\_aad(), etc.
+
+\subsubsection{One--Shot Packet}
+To process a single packet under any given key the following helper function can be used.
+
+\index{gcm\_memory()}
+\begin{verbatim}
+int gcm_memory(      int           cipher,
+               const unsigned char *key,    unsigned long keylen,
+               const unsigned char *IV,     unsigned long IVlen,
+               const unsigned char *adata,  unsigned long adatalen,
+                     unsigned char *pt,     unsigned long ptlen,
+                     unsigned char *ct, 
+                     unsigned char *tag,    unsigned long *taglen,
+                               int direction);
+\end{verbatim}
+
+This will initialize the GCM state with the given key, IV and AAD value then proceed to encrypt or decrypt the message text and store the final
+message tag.  The definition of the variables is the same as it is for all the manual functions.
+
+If you are processing many packets under the same key you shouldn't use this function as it invokes the pre--computation with each call.
+
+\subsubsection{Example Usage}
+The following is an example usage of how to use GCM over multiple packets with a shared secret key.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+
+int send_packet(const unsigned char *pt,  unsigned long ptlen,
+                const unsigned char *iv,  unsigned long ivlen,
+                const unsigned char *aad, unsigned long aadlen,
+                      gcm_state     *gcm)
+{
+   int           err;
+   unsigned long taglen;
+   unsigned char tag[16];
+
+   /* reset the state */
+   if ((err = gcm_reset(gcm)) != CRYPT_OK) {
+      return err;
+   }
+ 
+   /* Add the IV */
+   if ((err = gcm_add_iv(gcm, iv, ivlen)) != CRYPT_OK) {
+      return err;
+   }

+\chapter{One-Way Cryptographic Hash Functions}
+\section{Core Functions}
+
+Like the ciphers there are hash core functions and a universal data type to hold the hash state called ``hash\_state''.  
+To initialize hash XXX (where XXX is the name) call:
+\index{Hash Functions}
+\begin{verbatim}
+void XXX_init(hash_state *md);
+\end{verbatim}
+
+This simply sets up the hash to the default state governed by the specifications of the hash.  To add data to the 
+message being hashed call:
+\begin{verbatim}
+int XXX_process(hash_state *md, const unsigned char *in, unsigned long inlen);
+\end{verbatim}
+
+Essentially all hash messages are virtually infinitely\footnote{Most hashes are limited to $2^{64}$ bits or 2,305,843,009,213,693,952 bytes.} long message which 
+are buffered.  The data can be passed in any sized chunks as long as the order of the bytes are the same the message digest
+(hash output) will be the same.  For example, this means that:
+\begin{verbatim}
+md5_process(&md, "hello ", 6);
+md5_process(&md, "world", 5);
+\end{verbatim}
+Will produce the same message digest as the single call:
+\index{Message Digest}
+\begin{verbatim}
+md5_process(&md, "hello world", 11);
+\end{verbatim}
+
+To finally get the message digest (the hash) call:
+\begin{verbatim}
+int XXX_done(hash_state *md, 
+              unsigned char *out);
+\end{verbatim}
+
+This function will finish up the hash and store the result in the ``out'' array.  You must ensure that ``out'' is long
+enough for the hash in question.  Often hashes are used to get keys for symmetric ciphers so the ``XXX\_done()'' functions
+will wipe the ``md'' variable before returning automatically.
+
+To test a hash function call:
+\begin{verbatim}
+int XXX_test(void);
+\end{verbatim}
+
+This will return {\bf CRYPTO\_OK} if the hash matches the test vectors, otherwise it returns an error code.  An
+example snippet that hashes a message with md5 is given below.
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+    hash_state md;
+    unsigned char *in = "hello world", out[16];
+
+    /* setup the hash */
+    md5_init(&md);
+
+    /* add the message */
+    md5_process(&md, in, strlen(in));
+
+    /* get the hash in out[0..15] */
+    md5_done(&md, out);
+
+    return 0;
+}
+\end{verbatim}
+\end{small}
+
+\section{Hash Descriptors}
+Like the set of ciphers the set of hashes have descriptors too.  They are stored in an array called ``hash\_descriptor'' and
+are defined by:
+\begin{verbatim}
+struct _hash_descriptor {
+    char *name;
+    unsigned long hashsize;    /* digest output size in bytes  */
+    unsigned long blocksize;   /* the block size the hash uses */
+    void (*init)   (hash_state *hash);
+    int  (*process)(hash_state *hash, 
+                    const unsigned char *in, unsigned long inlen);
+    int  (*done)   (hash_state *hash, unsigned char *out);
+    int  (*test)   (void);
+};
+\end{verbatim}
+
+Similarly ``name'' is the name of the hash function in ASCII (all lowercase).  ``hashsize'' is the size of the digest output
+in bytes.  The remaining fields are pointers to the functions that do the respective tasks.  There is a function to
+search the array as well called ``int find\_hash(char *name)''.  It returns -1 if the hash is not found, otherwise the
+position in the descriptor table of the hash.
+
+You can use the table to indirectly call a hash function that is chosen at runtime.  For example:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   unsigned char buffer[100], hash[MAXBLOCKSIZE];
+   int idx, x;
+   hash_state md;
+
+   /* register hashes .... */
+   if (register_hash(&md5_desc) == -1) {
+      printf("Error registering MD5.\n");
+      return -1;
+   }
+
+   /* register other hashes ... */
+
+   /* prompt for name and strip newline */
+   printf("Enter hash name: \n");
+   fgets(buffer, sizeof(buffer), stdin);
+   buffer[strlen(buffer) - 1] = 0;
+
+   /* get hash index */
+   idx = find_hash(buffer);
+   if (idx == -1) {
+      printf("Invalid hash name!\n");
+      return -1;
+   }
+
+   /* hash input until blank line */
+   hash_descriptor[idx].init(&md);
+   while (fgets(buffer, sizeof(buffer), stdin) != NULL)
+         hash_descriptor[idx].process(&md, buffer, strlen(buffer));
+   hash_descriptor[idx].done(&md, hash);
+
+   /* dump to screen */
+   for (x = 0; x < hash_descriptor[idx].hashsize; x++)
+       printf("%02x ", hash[x]);
+   printf("\n");
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+Note the usage of ``MAXBLOCKSIZE''.  In Libtomcrypt no symmetric block, key or hash digest is larger than MAXBLOCKSIZE in
+length.  This provides a simple size you can set your automatic arrays to that will not get overrun.
+
+There are three helper functions as well:
+\index{hash\_memory()} \index{hash\_file()}
+\begin{verbatim}
+int hash_memory(int hash, 
+                const unsigned char *in,   unsigned long inlen, 
+                      unsigned char *out,  unsigned long *outlen);
+
+int hash_file(int hash, const char *fname, 
+              unsigned char *out, unsigned long *outlen);
+
+int hash_filehandle(int hash, FILE *in, 
+                    unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+
+The ``hash'' parameter is the location in the descriptor table of the hash (\textit{e.g. the return of find\_hash()}).  
+The ``*outlen'' variable is used to keep track of the output size.  You must set it to the size of your output buffer before 
+calling the functions.  When they complete succesfully they store the length of the message digest back in it.  The functions 
+are otherwise straightforward.  The ``hash\_filehandle'' function assumes that ``in'' is an file handle opened in binary mode.  
+It will hash to the end of file and not reset the file position when finished.
+
+To perform the above hash with md5 the following code could be used:
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int idx, err;
+   unsigned long len;
+   unsigned char out[MAXBLOCKSIZE];
+
+   /* register the hash */
+   if (register_hash(&md5_desc) == -1) {
+      printf("Error registering MD5.\n");
+      return -1;
+   }
+
+   /* get the index of the hash  */
+   idx = find_hash("md5");
+
+   /* call the hash */
+   len = sizeof(out);
+   if ((err = hash_memory(idx, "hello world", 11, out, &len)) != CRYPT_OK) {
+      printf("Error hashing data: %s\n", error_to_string(err));
+      return -1;
+   }
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+The following hashes are provided as of this release:
+\index{Hash descriptor table}
+\begin{center}
+\begin{tabular}{|c|c|c|}
+      \hline Name & Descriptor Name & Size of Message Digest (bytes) \\
+      \hline WHIRLPOOL & whirlpool\_desc & 64 \\
+      \hline SHA-512 & sha512\_desc & 64 \\
+      \hline SHA-384 & sha384\_desc & 48 \\
+      \hline SHA-256 & sha256\_desc & 32 \\
+      \hline SHA-224 & sha224\_desc & 28 \\
+      \hline TIGER-192 & tiger\_desc & 24 \\
+      \hline SHA-1 & sha1\_desc & 20 \\
+      \hline RIPEMD-160 & rmd160\_desc & 20 \\
+      \hline RIPEMD-128 & rmd128\_desc & 16 \\
+      \hline MD5 & md5\_desc & 16 \\
+      \hline MD4 & md4\_desc & 16 \\
+      \hline MD2 & md2\_desc & 16 \\
+      \hline
+\end{tabular}
+\end{center}
+
+Similar to the cipher descriptor table you must register your hash algorithms before you can use them.  These functions
+work exactly like those of the cipher registration code.  The functions are:
+\index{register\_hash()} \index{unregister\_hash()}
+\begin{verbatim}
+int register_hash(const struct _hash_descriptor *hash);
+int unregister_hash(const struct _hash_descriptor *hash);
+\end{verbatim}
+
+\section{Cipher Hash Construction}
+\index{Cipher Hash Construction}
+An addition to the suite of hash functions is the ``Cipher Hash Construction'' or ``CHC'' mode.  In this mode
+applicable block ciphers (such as AES) can be turned into hash functions that other LTC functions can use.  In 
+particular this allows a cryptosystem to be designed using very few moving parts.
+
+In order to use the CHC system the developer will have to take a few extra steps.  First the ``chc\_desc'' hash
+descriptor must be registered with register\_hash().  At this point the CHC hash cannot be used to hash
+data.  While it is in the hash system you still have to tell the CHC code which cipher to use.  This is accomplished
+via the chc\_register() function.
+
+\index{chc\_register()}
+\begin{verbatim}
+int chc_register(int cipher);
+\end{verbatim}
+
+A cipher has to be registered with CHC (and also in the cipher descriptor tables with 
+register\_cipher()).  The chc\_register() function will bind a cipher to the CHC system.  Only one cipher can 
+be bound to the CHC hash at a time.  There are additional requirements for the system to work.
+
+\begin{enumerate}
+   \item The cipher must have a block size greater than 64--bits.  
+   \item The cipher must allow an input key the size of the block size.
+\end{enumerate}
+
+Example of using CHC with the AES block cipher.
+
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int err; 
+
+   /* register cipher and hash */
+   if (register_cipher(&aes_enc_desc) == -1) {
+      printf("Could not register cipher\n");
+      return EXIT_FAILURE;
+   }
+   if (register_hash(&chc_desc) == -1) {
+      printf("Could not register hash\n");
+      return EXIT_FAILURE;
+   }
+
+   /* start chc with AES */
+   if ((err = chc_register(find_cipher("aes"))) != CRYPT_OK) {
+      printf("Error binding AES to CHC: %s\n", error_to_string(err));
+   }
+
+   /* now you can use chc_hash in any LTC function [aside from pkcs...] */
+   /* ... */
+\end{verbatim}
+
+
+\section{Notice}
+It is highly recommended that you \textbf{not} use the MD4 or MD5 hashes for the purposes of digital signatures or authentication codes.  
+These hashes are provided for completeness and they still can be used for the purposes of password hashing or one-way accumulators
+(e.g. Yarrow).
+
+The other hashes such as the SHA-1, SHA-2 (that includes SHA-512, SHA-384 and SHA-256) and TIGER-192 are still considered secure
+for all purposes you would normally use a hash for.
+
+\chapter{Message Authentication Codes}
+\section{HMAC Protocol}
+Thanks to Dobes Vandermeer the library now includes support for hash based message authenication codes or HMAC for short.  An HMAC
+of a message is a keyed authenication code that only the owner of a private symmetric key will be able to verify.  The purpose is
+to allow an owner of a private symmetric key to produce an HMAC on a message then later verify if it is correct.  Any impostor or
+eavesdropper will not be able to verify the authenticity of a message.  
+
+The HMAC support works much like the normal hash functions except that the initialization routine requires you to pass a key 
+and its length.  The key is much like a key you would pass to a cipher.  That is, it is simply an array of octets stored in
+chars.  The initialization routine is:
+\index{hmac\_init()}
+\begin{verbatim}
+int hmac_init(hmac_state *hmac, int hash, 
+              const unsigned char *key, unsigned long keylen);
+\end{verbatim}
+The ``hmac'' parameter is the state for the HMAC code.  ``hash'' is the index into the descriptor table of the hash you want
+to use to authenticate the message.  ``key'' is the pointer to the array of chars that make up the key.  ``keylen'' is the
+length (in octets) of the key you want to use to authenticate the message.  To send octets of a message through the HMAC system you must use the following function:
+\index{hmac\_process()}
+\begin{verbatim}
+int hmac_process(hmac_state *hmac, 
+                 const unsigned char *in, unsigned long inlen);
+\end{verbatim}
+``hmac'' is the HMAC state you are working with. ``buf'' is the array of octets to send into the HMAC process.  ``len'' is the
+number of octets to process.  Like the hash process routines you can send the data in arbitrarly sized chunks. When you 
+are finished with the HMAC process you must call the following function to get the HMAC code:
+\index{hmac\_done()}
+\begin{verbatim}
+int hmac_done(hmac_state *hmac, 
+              unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+``hmac'' is the HMAC state you are working with.  ``out'' is the array of octets where the HMAC code should be stored.  You must
+set ``outlen'' to the size of the destination buffer before calling this function.  It is updated with the length of the HMAC code
+produced (depending on which hash was picked).  If ``outlen'' is less than the size of the message digest (and ultimately
+the HMAC code) then the HMAC code is truncated as per FIPS-198 specifications (e.g. take the first ``outlen'' bytes).
+
+There are two  utility functions provided to make using HMACs easier todo.  They accept the key and information about the
+message (file pointer, address in memory) and produce the HMAC result in one shot.  These are useful if you want to avoid
+calling the three step process yourself.
+
+\index{hmac\_memory()}
+\begin{verbatim}
+int hmac_memory(int hash, 
+                const unsigned char *key, unsigned long  keylen,
+                const unsigned char *in,  unsigned long  inlen, 
+                      unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will produce an HMAC code for the array of octets in ``in'' of length ``inlen''.  The index into the hash descriptor 
+table must be provided in ``hash''.  It uses the key from ``key'' with a key length of ``keylen''.  
+The result is stored in the array of octets ``out'' and the length in ``outlen''.  The value of ``outlen'' must be set
+to the size of the destination buffer before calling this function.  Similarly for files there is the  following function:
+\index{hmac\_file()}
+\begin{verbatim}
+int hmac_file(int hash, const char *fname, 
+              const unsigned char *key, unsigned long  keylen, 
+                    unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+``hash'' is the index into the hash descriptor table of the hash you want to use.  ``fname'' is the filename to process.  
+``key'' is the array of octets to use as the key of length ``keylen''.  ``out'' is the array of octets where the 
+result should be stored.
+
+To test if the HMAC code is working there is the following function:
+\index{hmac\_test()}
+\begin{verbatim}
+int hmac_test(void);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if the code passes otherwise it returns an error code.  Some example code for using the 
+HMAC system is given below.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int idx, err;
+   hmac_state hmac;
+   unsigned char key[16], dst[MAXBLOCKSIZE];
+   unsigned long dstlen;
+
+   /* register SHA-1 */
+   if (register_hash(&sha1_desc) == -1) {
+      printf("Error registering SHA1\n");
+      return -1;
+   }
+
+   /* get index of SHA1 in hash descriptor table */
+   idx = find_hash("sha1");
+
+   /* we would make up our symmetric key in "key[]" here */
+
+   /* start the HMAC */
+   if ((err = hmac_init(&hmac, idx, key, 16)) != CRYPT_OK) {
+      printf("Error setting up hmac: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* process a few octets */
+   if((err = hmac_process(&hmac, "hello", 5) != CRYPT_OK) {
+      printf("Error processing hmac: %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* get result (presumably to use it somehow...) */
+   dstlen = sizeof(dst);
+   if ((err = hmac_done(&hmac, dst, &dstlen)) != CRYPT_OK) {
+      printf("Error finishing hmac: %s\n", error_to_string(err));
+      return -1;
+   }
+   printf("The hmac is %lu bytes long\n", dstlen);
+  
+   /* return */
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+\section{OMAC Support}
+OMAC\footnote{\url{http://crypt.cis.ibaraki.ac.jp/omac/omac.html}}, which stands for \textit{One-Key CBC MAC} is an 
+algorithm which produces a Message Authentication Code (MAC) using only a block cipher such as AES.  From an API 
+standpoint the OMAC routines work much like the HMAC routines do.  Instead in this case a cipher is used instead of a hash.  
+
+To start an OMAC state you call
+\index{omac\_init()}
+\begin{verbatim}
+int omac_init(omac_state *omac, int cipher, 
+              const unsigned char *key, unsigned long keylen);
+\end{verbatim}
+The ``omac'' variable is the state for the OMAC algorithm.  ``cipher'' is the index into the cipher\_descriptor table
+of the cipher\footnote{The cipher must have a 64 or 128 bit block size.  Such as CAST5, Blowfish, DES, AES, Twofish, etc.} you
+wish to use.  ``key'' and ``keylen'' are the keys used to authenticate the data.
+
+To send data through the algorithm call
+\index{omac\_process()}
+\begin{verbatim}
+int omac_process(omac_state *state, 
+                 const unsigned char *in, unsigned long inlen);
+\end{verbatim}
+This will send ``inlen'' bytes from ``in'' through the active OMAC state ``state''.  Returns \textbf{CRYPT\_OK} if the 
+function succeeds.  The function is not sensitive to the granularity of the data.  For example,
+
+\begin{verbatim}
+omac_process(&mystate, "hello",  5);
+omac_process(&mystate, " world", 6);
+\end{verbatim}
+
+Would produce the same result as,
+
+\begin{verbatim}
+omac_process(&mystate, "hello world",  11);
+\end{verbatim}
+
+When you are done processing the message you can call the following to compute the message tag.
+
+\index{omac\_done()}
+\begin{verbatim}
+int omac_done(omac_state *state, 
+              unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+Which will terminate the OMAC and output the \textit{tag} (MAC) to ``out''.  Note that unlike the HMAC and other code 
+``outlen'' can be smaller than the default MAC size (for instance AES would make a 16-byte tag).  Part of the OMAC 
+specification states that the output may be truncated.  So if you pass in $outlen = 5$ and use AES as your cipher than
+the output MAC code will only be five bytes long.  If ``outlen'' is larger than the default size it is set to the default
+size to show how many bytes were actually used.
+
+Similar to the HMAC code the file and memory functions are also provided.  To OMAC a buffer of memory in one shot use the 
+following function.
+
+\index{omac\_memory()}
+\begin{verbatim}
+int omac_memory(int cipher, 
+                const unsigned char *key, unsigned long keylen,
+                const unsigned char *in,  unsigned long inlen,
+                      unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will compute the OMAC of ``inlen'' bytes of ``in'' using the key ``key'' of length ``keylen'' bytes and the cipher
+specified by the ``cipher'''th entry in the cipher\_descriptor table.  It will store the MAC in ``out'' with the same
+rules as omac\_done.
+
+To OMAC a file use
+\index{omac\_file()}
+\begin{verbatim}
+int omac_file(int cipher, 
+              const unsigned char *key, unsigned long keylen,
+              const char *filename, 
+                    unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+
+Which will OMAC the entire contents of the file specified by ``filename'' using the key ``key'' of length ``keylen'' bytes
+and the cipher specified by the ``cipher'''th entry in the cipher\_descriptor table.  It will store the MAC in ``out'' with 
+the same rules as omac\_done.
+
+To test if the OMAC code is working there is the following function:
+\index{omac\_test()}
+\begin{verbatim}
+int omac_test(void);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if the code passes otherwise it returns an error code.  Some example code for using the 
+OMAC system is given below.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int idx, err;
+   omac_state omac;
+   unsigned char key[16], dst[MAXBLOCKSIZE];
+   unsigned long dstlen;
+
+   /* register Rijndael */
+   if (register_cipher(&rijndael_desc) == -1) {
+      printf("Error registering Rijndael\n");
+      return -1;
+   }
+
+   /* get index of Rijndael in cipher descriptor table */
+   idx = find_cipher("rijndael");
+
+   /* we would make up our symmetric key in "key[]" here */

+\section{PMAC Support}
+The PMAC\footnote{J.Black, P.Rogaway, ``A Block--Cipher Mode of Operation for Parallelizable Message Authentication''} 
+protocol is another MAC algorithm that relies solely on a symmetric-key block cipher.  It uses essentially the same
+API as the provided OMAC code.  
+
+A PMAC state is initialized with the following.
+
+\index{pmac\_init()}
+\begin{verbatim}
+int pmac_init(pmac_state *pmac, int cipher, 
+              const unsigned char *key, unsigned long keylen);
+\end{verbatim}
+Which initializes the ``pmac'' state with the given ``cipher'' and ``key'' of length ``keylen'' bytes.  The chosen cipher
+must have a 64 or 128 bit block size (e.x. AES).
+
+To MAC data simply send it through the process function.
+
+\index{pmac\_process()}
+\begin{verbatim}
+int pmac_process(pmac_state *state, 
+                 const unsigned char *in, unsigned long inlen);
+\end{verbatim}
+This will process ``inlen'' bytes of ``in'' in the given ``state''.  The function is not sensitive to the granularity of the
+data.  For example,
+
+\begin{verbatim}
+pmac_process(&mystate, "hello",  5);
+pmac_process(&mystate, " world", 6);
+\end{verbatim}
+
+Would produce the same result as,
+
+\begin{verbatim}
+pmac_process(&mystate, "hello world",  11);
+\end{verbatim}
+
+When a complete message has been processed the following function can be called to compute the message tag.
+
+\index{pmac\_done()}
+\begin{verbatim}
+int pmac_done(pmac_state *state, 
+              unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will store upto ``outlen'' bytes of the tag for the given ``state'' into ``out''.  Note that if ``outlen'' is larger
+than the size of the tag it is set to the amount of bytes stored in ``out''.
+
+Similar to the PMAC code the file and memory functions are also provided.  To PMAC a buffer of memory in one shot use the 
+following function.
+
+\index{pmac\_memory()}
+\begin{verbatim}
+int pmac_memory(int cipher, 
+                const unsigned char *key, unsigned long  keylen,
+                const unsigned char *in,  unsigned long  inlen,
+                      unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+This will compute the PMAC of ``msglen'' bytes of ``msg'' using the key ``key'' of length ``keylen'' bytes and the cipher
+specified by the ``cipher'''th entry in the cipher\_descriptor table.  It will store the MAC in ``out'' with the same
+rules as omac\_done.
+
+To PMAC a file use
+\index{pmac\_file()}
+\begin{verbatim}
+int pmac_file(int cipher, 
+              const unsigned char *key, unsigned long keylen,
+              const char *filename, 
+              unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+
+Which will PMAC the entire contents of the file specified by ``filename'' using the key ``key'' of length ``keylen'' bytes
+and the cipher specified by the ``cipher'''th entry in the cipher\_descriptor table.  It will store the MAC in ``out'' with 
+the same rules as omac\_done.
+
+To test if the PMAC code is working there is the following function:
+\index{pmac\_test()}
+\begin{verbatim}
+int pmac_test(void);
+\end{verbatim}
+Which returns {\bf CRYPT\_OK} if the code passes otherwise it returns an error code.
+
+\section{Pelican MAC}
+Pelican MAC is a new (experimental) MAC by the AES team that uses four rounds of AES as a ``mixing function''.  It achieves a very high 
+rate of processing and is potentially very secure.  It requires AES to be enabled to function.  You do not have to register\_cipher() AES first though
+as it calls AES directly.
+
+\index{pelican\_init()}
+\begin{verbatim}
+int pelican_init(pelican_state *pelmac, const unsigned char *key, unsigned long keylen);
+\end{verbatim}
+This will initialize the Pelican state with the given AES key.  Once this has been done you can begin processing data.
+
+\index{pelican\_process()}
+\begin{verbatim}
+int pelican_process(pelican_state *pelmac, const unsigned char *in, unsigned long inlen);
+\end{verbatim}
+This will process ``inlen'' bytes of ``in'' through the Pelican MAC.  It's best that you pass in multiples of 16 bytes as it makes the
+routine more efficient but you may pass in any length of text.  You can call this function as many times as required to process
+an entire message.
+
+\index{pelican\_done()}
+\begin{verbatim}
+int pelican_done(pelican_state *pelmac, unsigned char *out);
+\end{verbatim}
+This terminates a Pelican MAC and writes the 16--octet tag to ``out''.
+
+\subsection{Example}
+
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   pelican_state pelstate;
+   unsigned char key[32], tag[16];
+   int           err;
+
+   /* somehow initialize a key */
+
+   /* initialize pelican mac */
+   if ((err = pelican_init(&pelstate,          /* the state */
+                           key,                /* user key */
+                           32                  /* key length in octets */
+                          )) != CRYPT_OK) {
+      printf("Error initializing Pelican: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* MAC some data */
+   if ((err = pelican_process(&pelstate,       /* the state */
+                              "hello world",   /* data to mac */        
+                              11               /* length of data */
+                              )) != CRYPT_OK) {
+      printf("Error processing Pelican: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* Terminate the MAC */
+   if ((err = pelican_done(&pelstate,       /* the state */
+                           tag              /* where to store the tag */
+                           )) != CRYPT_OK) {
+      printf("Error terminating Pelican: %s", error_to_string(err));
+      return EXIT_FAILURE;
+   }
+
+   /* tag[0..15] has the MAC output now */
+
+   return EXIT_SUCCESS;
+}
+\end{verbatim}
+
+
+\chapter{Pseudo-Random Number Generators}
+\section{Core Functions}
+The library provides an array of core functions for Pseudo-Random Number Generators (PRNGs) as well.  A cryptographic PRNG is
+used to expand a shorter bit string into a longer bit string.  PRNGs are used wherever random data is required such as Public Key (PK)
+key generation.  There is a universal structure called ``prng\_state''.  To initialize a PRNG call:
+\index{PRNG start}
+\begin{verbatim}
+int XXX_start(prng_state *prng);
+\end{verbatim}
+
+This will setup the PRNG for future use and not seed it.  In order for the PRNG to be cryptographically useful you must give it 
+entropy.  Ideally you'd have some OS level source to tap like in UNIX.  To add entropy to the PRNG call:
+\index{PRNG add\_entropy}
+\begin{verbatim}
+int XXX_add_entropy(const unsigned char *in, unsigned long inlen, 
+                    prng_state *prng);
+\end{verbatim}
+
+Which returns {\bf CRYPTO\_OK} if the entropy was accepted.  Once you think you have enough entropy you call another
+function to put the entropy into action.
+\index{PRNG ready}
+\begin{verbatim}
+int XXX_ready(prng_state *prng);
+\end{verbatim}
+
+Which returns {\bf CRYPTO\_OK} if it is ready.  Finally to actually read bytes call:
+\index{PRNG read}
+\begin{verbatim}
+unsigned long XXX_read(unsigned char *out, unsigned long outlen,
+                       prng_state *prng);
+\end{verbatim}
+
+Which returns the number of bytes read from the PRNG.  When you are finished with a PRNG state you call
+the following.
+
+\index{PRNG done}
+\begin{verbatim}
+void XXX_done(prng_state *prng);
+\end{verbatim}
+
+This will terminate a PRNG state and free any memory (if any) allocated.  To export a PRNG state
+so that you can later resume the PRNG call the following.
+
+\index{PRNG export}
+\begin{verbatim}
+int XXX_export(unsigned char *out, unsigned long *outlen, 
+               prng_state    *prng);
+\end{verbatim}
+
+This will write a ``PRNG state'' to the buffer ``out'' of length ``outlen'' bytes.  The idea of 
+the export is meant to be used as a ``seed file''.  That is, when the program starts up there will not likely
+be that much entropy available.   To import a state to seed a PRNG call the following function.
+
+\index{PRNG import}
+\begin{verbatim}
+int XXX_import(const unsigned char *in, unsigned long inlen, 
+                     prng_state     *prng);
+\end{verbatim}
+
+This will call the start and add\_entropy functions of the given PRNG.  It will use the state in
+``in'' of length ``inlen'' as the initial seed.  You must pass the same seed length as was exported
+by the corresponding export function.
+
+Note that importing a state will not ``resume'' the PRNG from where it left off.  That is, if you export
+a state, emit (say) 8 bytes and then import the previously exported state the next 8 bytes will not 
+specifically equal the 8 bytes you generated previously.
+
+When a program is first executed the normal course of operation is 
+
+\begin{enumerate}
+   \item Gather entropy from your sources for a given period of time or number of events.
+   \item Start, use your entropy via add\_entropy and ready the PRNG yourself.
+\end{enumerate}
+
+When your program is finished you simply call the export function and save the state to a medium (disk,
+flash memory, etc).  The next time your application starts up you can detect the state, feed it to the 
+import function and go on your way.  It is ideal that (as soon as possible) after startup you export a
+fresh state.  This helps in the case that the program aborts or the machine is powered down without
+being given a chance to exit properly.  
+
+Note that even if you have a state to import it is important to add new entropy to the state.  However,
+there is less pressure to do so.  
+
+To test a PRNG for operational conformity call the following functions.
+
+\index{PRNG test}
+\begin{verbatim}
+int XXX_test(void);
+\end{verbatim}
+
+This will return \textbf{CRYPT\_OK} if PRNG is operating properly.
+
+\subsection{Remarks}
+
+It is possible to be adding entropy and reading from a PRNG at the same time.  For example, if you first seed the PRNG
+and call ready() you can now read from it.  You can also keep adding new entropy to it.  The new entropy will not be used
+in the PRNG until ready() is called again.  This allows the PRNG to be used and re-seeded at the same time.  No real error 
+checking is guaranteed to see if the entropy is sufficient or if the PRNG is even in a ready state before reading.
+
+\subsection{Example}
+
+Below is a simple snippet to read 10 bytes from yarrow.  Its important to note that this snippet is 
+{\bf NOT} secure since the entropy added is not random.
+
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   prng_state prng;
+   unsigned char buf[10];
+   int err;
+   
+   /* start it */
+   if ((err = yarrow_start(&prng)) != CRYPT_OK) {
+      printf("Start error: %s\n", error_to_string(err));
+   }
+   /* add entropy */
+   if ((err = yarrow_add_entropy("hello world", 11, &prng)) != CRYPT_OK) {
+      printf("Add_entropy error: %s\n", error_to_string(err));
+   }
+   /* ready and read */
+   if ((err = yarrow_ready(&prng)) != CRYPT_OK) {
+      printf("Ready error: %s\n", error_to_string(err));
+   }
+   printf("Read %lu bytes from yarrow\n", yarrow_read(buf, 10, &prng));
+   return 0;
+}
+\end{verbatim}
+
+\section{PRNG Descriptors}
+\index{PRNG Descriptor}
+PRNGs have descriptors too (surprised?). Stored in the structure ``prng\_descriptor''.  The format of an element is:
+\begin{verbatim}
+struct _prng_descriptor {
+    char *name;
+    int  export_size;    /* size in bytes of exported state */
+    int (*start)      (prng_state *);
+    int (*add_entropy)(const unsigned char *, unsigned long, prng_state *);
+    int (*ready)      (prng_state *);
+    unsigned long (*read)(unsigned char *, unsigned long len, prng_state *);
+    void (*done)(prng_state *);
+    int (*export)(unsigned char *, unsigned long *, prng_state *);
+    int (*import)(const unsigned char *, unsigned long, prng_state *);
+    int (*test)(void);
+};
+\end{verbatim}
+
+There is a ``int find\_prng(char *name)'' function as well.  Returns -1 if the PRNG is not found, otherwise it returns
+the position in the prng\_descriptor array.
+
+Just like the ciphers and hashes you must register your prng before you can use it.  The two functions provided work
+exactly as those for the cipher registry functions.  They are:
+\begin{verbatim}
+int register_prng(const struct _prng_descriptor *prng);
+int unregister_prng(const struct _prng_descriptor *prng);
+\end{verbatim}
+
+\subsection{PRNGs Provided}
+\begin{figure}[here]
+\begin{center}
+\begin{small}
+\begin{tabular}{|c|c|l|}
+\hline \textbf{Name} & \textbf{Descriptor} & \textbf{Usage} \\
+\hline Yarrow & yarrow\_desc & Fast short-term PRNG \\
+\hline Fortuna & fortuna\_desc & Fast long-term PRNG (recommended) \\
+\hline RC4 & rc4\_desc & Stream Cipher \\
+\hline SOBER-128 & sober128\_desc & Stream Cipher (also very fast PRNG) \\
+\hline
+\end{tabular}
+\end{small}
+\end{center}
+\caption{List of Provided PRNGs}
+\end{figure}
+
+\subsubsection{Yarrow}
+Yarrow is fast PRNG meant to collect an unspecified amount of entropy from sources 
+(keyboard, mouse, interrupts, etc) and produce an unbounded string of random bytes.  
+
+\textit{Note:} This PRNG is still secure for most taskings but is no longer recommended.  Users
+should use Fortuna instead.
+
+\subsubsection{Fortuna}
+
+Fortuna is a fast attack tolerant and more thoroughly designed PRNG suitable for long term
+usage.  It is faster than the default implementation of Yarrow\footnote{Yarrow has been implemented
+to work with most cipher and hash combos based on which you have chosen to build into the library.} while
+providing more security.  
+
+Fortuna is slightly less flexible than Yarrow in the sense that it only works with the AES block cipher 
+and SHA--256 hash function.  Technically Fortuna will work with any block cipher that accepts a 256--bit
+key and any hash that produces at least a 256--bit output.  However, to make the implementation simpler
+it has been fixed to those choices.
+
+Fortuna is more secure than Yarrow in the sense that attackers who learn parts of the entropy being 
+added to the PRNG learn far less about the state than that of Yarrow.  Without getting into to many
+details Fortuna has the ability to recover from state determination attacks where the attacker starts
+to learn information from the PRNGs output about the internal state.  Yarrow on the other hand cannot 
+recover from that problem until new entropy is added to the pool and put to use through the ready() function.
+
+\subsubsection{RC4}
+
+RC4 is an old stream cipher that can also double duty as a PRNG in a pinch.  You ``key'' it by
+calling add\_entropy() and setup the key by calling ready().  You can only add upto 256 bytes via
+add\_entropy().  
+
+When you read from RC4 the output of the RC4 algorithm is XOR'd against your buffer you provide.  In this
+manner you can use rc4\_read() as an encrypt (and decrypt) function.  
+
+You really shouldn't use RC4 anymore.  This isn't because RC4 is weak (though biases are known to exist) just
+simply that faster alternatives exist.
+
+\subsubsection{SOBER-128}
+
+SOBER-128 is a stream cipher designed by the QUALCOMM Australia team.  Like RC4 you ``key'' it by 
+calling add\_entropy().  There is no need to call ready() for this PRNG as it does not do anything.  
+
+Note that this cipher has several oddities about how it operates.  The first time you call 
+add\_entropy() that sets the cipher's key.  Every other time you call the same function it sets
+the cipher's IV variable.  The IV mechanism allows you to encrypt several messages with the same
+key and not re--use the same key material.
+
+Unlike Yarrow and Fortuna all of the entropy (and hence security) of this algorithm rests in the data
+you pass it on the first call to add\_entropy().  All buffers sent to add\_entropy() must have a length
+that is a multiple of four bytes.
+
+Like RC4 the output of SOBER--128 is XOR'ed against the buffer you provide it.  In this manner you can use
+sober128\_read() as an encrypt (and decrypt) function.
+
+Since SOBER-128 has a fixed keying scheme and is very fast (faster than RC4) the ideal usage of SOBER-128 is to 
+key it from the output of Fortuna (or Yarrow) and use it to encrypt messages.  It is also ideal for
+simulations which need a high quality (and fast) stream of bytes.  
+
+\subsubsection{Example Usage}
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   prng_state prng;
+   unsigned char buf[32];
+   int err;
+
+   if ((err = rc4_start(&prng)) != CRYPT_OK) {
+      printf("RC4 init error: %s\n", error_to_string(err));
+      exit(-1);
+   }
+
+   /* use ``key'' as the key */
+   if ((err = rc4_add_entropy("key", 3, &prng)) != CRYPT_OK) {
+      printf("RC4 add entropy error: %s\n", error_to_string(err));
+      exit(-1);
+   }
+
+   /* setup RC4 for use */
+   if ((err = rc4_ready(&prng)) != CRYPT_OK) {
+      printf("RC4 ready error: %s\n", error_to_string(err));
+      exit(-1);
+   }
+
+   /* encrypt buffer */
+   strcpy(buf,"hello world");
+   if (rc4_read(buf, 11, &prng) != 11) {
+      printf("RC4 read error\n");
+      exit(-1);
+   }
+   return 0;
+}   
+\end{verbatim}
+\end{small}
+To decrypt you have to do the exact same steps.  
+
+\section{The Secure RNG}
+\index{Secure RNG}
+An RNG is related to a PRNG except that it doesn't expand a smaller seed to get the data.  They generate their random bits
+by performing some computation on fresh input bits.  Possibly the hardest thing to get correctly in a cryptosystem is the 
+PRNG.  Computers are deterministic beasts that try hard not to stray from pre-determined paths.  That makes gathering 
+entropy needed to seed the PRNG a hard task.  
+
+There is one small function that may help on certain platforms:
+\index{rng\_get\_bytes()}
+\begin{verbatim}
+unsigned long rng_get_bytes(unsigned char *buf, unsigned long len, 
+                  void (*callback)(void));
+\end{verbatim}
+
+Which will try one of three methods of getting random data.  The first is to open the popular ``/dev/random'' device which 
+on most *NIX platforms provides cryptographic random bits\footnote{This device is available in Windows through the Cygwin compiler suite.  It emulates ``/dev/random'' via the Microsoft CSP.}.  
+The second method is to try the Microsoft Cryptographic Service Provider and read the RNG.  The third method is an ANSI C 
+clock drift method that is also somewhat popular but gives bits of lower entropy.  The ``callback'' parameter is a pointer to a function that returns void.  Its used when the slower ANSI C RNG must be 
+used so the calling application can still work.  This is useful since the ANSI C RNG has a throughput of three 
+bytes a second.  The callback pointer may be set to {\bf NULL} to avoid using it if you don't want to.  The function 
+returns the number of bytes actually read from any RNG source.  There is a function to help setup a PRNG as well:
+\index{rng\_make\_prng()}
+\begin{verbatim}
+int rng_make_prng(int bits, int wprng, prng_state *prng, 
+                  void (*callback)(void));
+\end{verbatim}
+This will try to setup the prng with a state of at least ``bits'' of entropy.  The ``callback'' parameter works much like
+the callback in ``rng\_get\_bytes()''.  It is highly recommended that you use this function to setup your PRNGs unless you have a
+platform where the RNG doesn't work well.  Example usage of this function is given below.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   ecc_key mykey;
+   prng_state prng;
+   int err;
+
+   /* register yarrow */
+   if (register_prng(&yarrow_desc) == -1) {
+      printf("Error registering Yarrow\n");
+      return -1;
+   }
+
+   /* setup the PRNG */
+   if ((err = rng_make_prng(128, find_prng("yarrow"), &prng, NULL)) != CRYPT_OK) {
+      printf("Error setting up PRNG, %s\n", error_to_string(err));
+      return -1;
+   }
+
+   /* make a 192-bit ECC key */
+   if ((err = ecc_make_key(&prng, find_prng("yarrow"), 24, &mykey)) != CRYPT_OK) {
+      printf("Error making key: %s\n", error_to_string(err));
+      return -1;
+   }
+   return 0;
+}
+\end{verbatim}
+\end{small}
+
+\subsection{The Secure PRNG Interface}
+It is possible to access the secure RNG through the PRNG interface and in turn use it within dependent functions such
+as the PK API.  This simplifies the cryptosystem on platforms where the secure RNG is fast.  The secure PRNG never 
+requires to be started, that is you need not call the start, add\_entropy or ready functions.  For example, consider
+the previous example using this PRNG.
+
+\begin{small}
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   ecc_key mykey;
+   int err;
+
+   /* register SPRNG */
+   if (register_prng(&sprng_desc) == -1) {
+      printf("Error registering SPRNG\n");
+      return -1;
+   }
+
+   /* make a 192-bit ECC key */
+   if ((err = ecc_make_key(NULL, find_prng("sprng"), 24, &mykey)) != CRYPT_OK) {
+      printf("Error making key: %s\n", error_to_string(err));
+      return -1;
+   }
+   return 0;
+}
+\end{verbatim}
+\end{small}

+\chapter{RSA Public Key Cryptography}
+
+\section{Introduction}
+RSA wrote the PKCS \#1 specifications which detail RSA Public Key Cryptography.  In the specifications are
+padding algorithms for encryption and signatures.  The standard includes the ``v2.1'' algorithms.
+To simplify matters a little the v2.1 encryption and signature padding algorithms are called OAEP and PSS 
+respectively.  
+
+\section{PKCS \#1 Encryption}
+
+PKCS \#1 RSA Encryption amounts to OAEP padding of the input message followed by the modular exponentiation.  As far as this portion of
+the library is concerned we are only dealing with th OAEP padding of the message.
+
+\subsection{OAEP Encoding}
+
+\index{pkcs\_1\_oaep\_encode()}
+\begin{alltt}
+int pkcs_1_oaep_encode(const unsigned char *msg,    unsigned long msglen,
+                       const unsigned char *lparam, unsigned long lparamlen,
+                             unsigned long modulus_bitlen, prng_state *prng,
+                             int           prng_idx,         int  hash_idx,
+                             unsigned char *out,    unsigned long *outlen);
+\end{alltt}
+
+This accepts ``msg'' as input of length ``msglen'' which will be OAEP padded.  The ``lparam'' variable is an additional system specific
+tag that can be applied to the encoding.  This is useful to identify which system encoded the message.  If no variance is desired then
+``lparam'' can be set to \textbf{NULL}.  
+
+OAEP encoding requires the length of the modulus in bits in order to calculate the size of the output.  This is passed as the parameter
+``modulus\_bitlen''.  ``hash\_idx'' is the index into the hash descriptor table of the hash desired.  PKCS \#1 allows any hash to be 
+used but both the encoder and decoder must use the same hash in order for this to succeed.  The size of hash output affects the maximum
+ sized input message.  ``prng\_idx'' and ``prng'' are the random number generator arguments required to randomize the padding process.  
+The padded message is stored in ``out'' along with the length in ``outlen''.
+
+If $h$ is the length of the hash and $m$ the length of the modulus (both in octets) then the maximum payload for ``msg'' is 
+$m - 2h - 2$.  For example, with a $1024$--bit RSA key and SHA--1 as the hash the maximum payload is $86$ bytes.  
+
+Note that when the message is padded it still has not been RSA encrypted.  You must pass the output of this function to 
+rsa\_exptmod() to encrypt it. 
+
+\subsection{OAEP Decoding}
+
+\index{pkcs\_1\_oaep\_decode()}
+\begin{alltt}
+int pkcs_1_oaep_decode(const unsigned char *msg,    unsigned long msglen,
+                       const unsigned char *lparam, unsigned long lparamlen,
+                             unsigned long modulus_bitlen, int hash_idx,
+                             unsigned char *out,    unsigned long *outlen,
+                             int           *res);
+\end{alltt}
+
+This function decodes an OAEP encoded message and outputs the original message that was passed to the OAEP encoder.  ``msg'' is the 
+output of pkcs\_1\_oaep\_encode() of length ``msglen''.  ``lparam'' is the same system variable passed to the OAEP encoder.  If it does not
+match what was used during encoding this function will not decode the packet.  ``modulus\_bitlen'' is the size of the RSA modulus in bits
+and must match what was used during encoding.  Similarly the ``hash\_idx'' index into the hash descriptor table must match what was used
+during encoding.
+
+If the function succeeds it decodes the OAEP encoded message into ``out'' of length ``outlen'' and stores a 
+$1$ in ``res''.  If the packet is invalid it stores $0$ in ``res'' and if the function fails for another reason
+it returns an error code.  
+
+\section{PKCS \#1 Digital Signatures}
+
+\subsection{PSS Encoding}
+PSS encoding is the second half of the PKCS \#1 standard which is padding to be applied to messages that are signed.  
+
+\index{pkcs\_1\_pss\_encode()}
+\begin{alltt}
+int pkcs_1_pss_encode(const unsigned char *msghash, unsigned long msghashlen,
+                            unsigned long saltlen,  prng_state   *prng,     
+                            int           prng_idx, int           hash_idx,
+                            unsigned long modulus_bitlen,
+                            unsigned char *out,     unsigned long *outlen);
+\end{alltt}
+
+This function assumes the message to be PSS encoded has previously been hashed.  The input hash ``msghash'' is of length 
+``msghashlen''.  PSS allows a variable length random salt (it can be zero length) to be introduced in the signature process.  
+``hash\_idx'' is the index into the hash descriptor table of the hash to use.  ``prng\_idx'' and ``prng'' are the random
+number generator information required for the salt.
+
+Similar to OAEP encoding ``modulus\_bitlen'' is the size of the RSA modulus (in bits).  It limits the size of the salt.  If $m$ is the length
+of the modulus $h$ the length of the hash output (in octets) then there can be $m - h - 2$ bytes of salt.  
+
+This function does not actually sign the data it merely pads the hash of a message so that it can be processed by rsa\_exptmod().
+
+\subsection{PSS Decoding}
+
+To decode a PSS encoded signature block you have to use the following.
+
+\index{pkcs\_1\_pss\_decode()}
+\begin{alltt}
+int pkcs_1_pss_decode(const unsigned char *msghash, unsigned long msghashlen,
+                      const unsigned char *sig,     unsigned long siglen,
+                            unsigned long saltlen,  int           hash_idx,
+                            unsigned long modulus_bitlen, int    *res);
+\end{alltt}
+This will decode the PSS encoded message in ``sig'' of length ``siglen'' and compare it to values in ``msghash'' of length
+``msghashlen''.  If the block is a valid PSS block and the decoded hash equals the hash supplied ``res'' is set to non--zero.  Otherwise, 
+it is set to zero.  The rest of the parameters are as in the PSS encode call.
+
+It's important to use the same ``saltlen'' and hash for both encoding and decoding as otherwise the procedure will not work.
+
+\section{RSA Operations}
+\subsection{Background}
+
+RSA is a public key algorithm that is based on the inability to find the ``e-th'' root modulo a composite of unknown 
+factorization.  Normally the difficulty of breaking RSA is associated with the integer factoring problem but they are
+not strictly equivalent.
+
+The system begins with with two primes $p$ and $q$ and their product $N = pq$.  The order or ``Euler totient'' of the
+multiplicative sub-group formed modulo $N$ is given as $\phi(N) = (p - 1)(q - 1)$ which can be reduced to 
+$\mbox{lcm}(p - 1, q - 1)$.  The public key consists of the composite $N$ and some integer $e$ such that 
+$\mbox{gcd}(e, \phi(N)) = 1$.  The private key consists of the composite $N$ and the inverse of $e$ modulo $\phi(N)$ 
+often simply denoted as $de \equiv 1\mbox{ }(\mbox{mod }\phi(N))$.
+
+A person who wants to encrypt with your public key simply forms an integer (the plaintext) $M$ such that 
+$1 < M < N-2$ and computes the ciphertext $C = M^e\mbox{ }(\mbox{mod }N)$.  Since finding the inverse exponent $d$
+given only $N$ and $e$ appears to be intractable only the owner of the private key can decrypt the ciphertext and compute
+$C^d \equiv \left (M^e \right)^d \equiv M^1 \equiv M\mbox{ }(\mbox{mod }N)$.  Similarly the owner of the private key 
+can sign a message by ``decrypting'' it.  Others can verify it by ``encrypting'' it.  
+
+Currently RSA is a difficult system to cryptanalyze provided that both primes are large and not close to each other.  
+Ideally $e$ should be larger than $100$ to prevent direct analysis.  For example, if $e$ is three and you do not pad
+the plaintext to be encrypted than it is possible that $M^3 < N$ in which case finding the cube-root would be trivial.  
+The most often suggested value for $e$ is $65537$ since it is large enough to make such attacks impossible and also well 
+designed for fast exponentiation (requires 16 squarings and one multiplication).
+
+It is important to pad the input to RSA since it has particular mathematical structure.  For instance  
+$M_1^dM_2^d = (M_1M_2)^d$ which can be used to forge a signature.  Suppose $M_3 = M_1M_2$ is a message you want
+to have a forged signature for.  Simply get the signatures for $M_1$ and $M_2$ on their own and multiply the result
+together.  Similar tricks can be used to deduce plaintexts from ciphertexts.  It is important not only to sign 
+the hash of documents only but also to pad the inputs with data to remove such structure.  
+
+\subsection{RSA Key Generation}
+
+For RSA routines a single ``rsa\_key'' structure is used.  To make a new RSA key call:
+\index{rsa\_make\_key()}
+\begin{verbatim}
+int rsa_make_key(prng_state *prng, 
+                 int wprng, int size, 
+                 long e, rsa_key *key);
+\end{verbatim}
+
+Where ``wprng'' is the index into the PRNG descriptor array.  ``size'' is the size in bytes of the RSA modulus desired.
+``e'' is the encryption exponent desired, typical values are 3, 17, 257 and 65537.  I suggest you stick with 65537 since its big
+enough to prevent trivial math attacks and not super slow.  ``key'' is where the key is placed.  All keys must be at 
+least 128 bytes and no more than 512 bytes in size (\textit{that is from 1024 to 4096 bits}).
+
+Note that the ``rsa\_make\_key()'' function allocates memory at runtime when you make the key.  Make sure to call 
+``rsa\_free()'' (see below) when you are finished with the key.  If ``rsa\_make\_key()'' fails it will automatically 
+free the ram allocated itself.
+
+\index{PK\_PRIVATE} \index{PK\_PUBLIC}
+There are two types of RSA keys.  The types are {\bf PK\_PRIVATE} and {\bf PK\_PUBLIC}.  The first type is a private 
+RSA key which includes the CRT parameters\footnote{As of v0.99 the PK\_PRIVATE\_OPTIMIZED type has been deprecated
+and has been replaced by the PK\_PRIVATE type.} in the form of a RSAPrivateKey.  The second type is a public RSA key
+which only includes the modulus and public exponent.  It takes the form of a RSAPublicKey.
+
+\subsection{RSA Exponentiation}
+
+To do raw work with the RSA function call:
+\index{rsa\_exptmod()}
+\begin{verbatim}
+int rsa_exptmod(const unsigned char *in,   unsigned long inlen,
+                      unsigned char *out,  unsigned long *outlen, 
+                      int which, prng_state *prng, int prng_idx,
+                      rsa_key *key);
+\end{verbatim}
+This loads the bignum from ``in'' as a big endian word in the format PKCS specifies, raises it to either ``e'' or ``d'' and stores the result
+in ``out'' and the size of the result in ``outlen''. ``which'' is set to {\bf PK\_PUBLIC} to use ``e'' 
+(i.e. for encryption/verifying) and set to {\bf PK\_PRIVATE} to use ``d'' as the exponent (i.e. for decrypting/signing).
+
+Note that the output of his function is zero-padded as per PKCS \#1 specifications.  This allows this routine to 
+interoprate with PKCS \#1 padding functions properly.
+
+\subsection{RSA Key Encryption}
+Normally RSA is used to encrypt short symmetric keys which are then used in block ciphers to encrypt a message.
+To facilitate encrypting short keys the following functions have been provided.
+
+\index{rsa\_encrypt\_key()}
+\begin{verbatim}
+int rsa_encrypt_key(const unsigned char *in,  unsigned long inlen,
+                          unsigned char *out, unsigned long *outlen,
+                    const unsigned char *lparam, unsigned long lparamlen,
+                    prng_state *prng, int prng_idx, int hash_idx, rsa_key *key);
+\end{verbatim}
+This function will OAEP pad ``in'' of length inlen bytes then RSA encrypt it and store the ciphertext
+in ``out'' of length ``outlen''.  The ``lparam'' and ``lparamlen'' are the same parameters you would pass
+to pkcs\_1\_oaep\_encode().
+
+\index{rsa\_decrypt\_key()}
+\begin{verbatim}
+int rsa_decrypt_key(const unsigned char *in,  unsigned long inlen,
+                          unsigned char *out, unsigned long *outlen, 
+                    const unsigned char *lparam, unsigned long lparamlen,
+                          int            hash_idx, int *stat,
+                          rsa_key       *key);
+\end{verbatim}
+This function will RSA decrypt ``in'' of length ``inlen'' then OAEP depad the resulting data and store it in
+``out'' of length ``outlen''.  The ``lparam'' and ``lparamlen'' are the same parameters you would pass
+to pkcs\_1\_oaep\_decode().
+
+If the RSA decrypted data isn't a valid OAEP packet then ``stat'' is set to $0$.  Otherwise, it is set to $1$.
+
+\subsection{RSA Hash Signatures}
+Similar to RSA key encryption RSA is also used to ``digitally sign'' message digests (hashes).  To facilitate this
+process the following functions have been provided.
+
+\index{rsa\_sign\_hash()}
+\begin{verbatim}
+int rsa_sign_hash(const unsigned char *in,   unsigned long  inlen, 
+                        unsigned char *out,  unsigned long *outlen, 
+                        prng_state    *prng,     int            prng_idx,
+                        int            hash_idx, unsigned long  saltlen,
+                        rsa_key *key);
+\end{verbatim}
+
+This will PSS encode the message hash ``in'' of length ``inlen''.  Next the PSS encoded message will be RSA ``signed'' and 
+the output is stored in ``out'' of length ``outlen''.  
+
+
+\index{rsa\_verify\_hash()}
+\begin{verbatim}
+int rsa_verify_hash(const unsigned char *sig,      unsigned long siglen,
+                    const unsigned char *msghash,  unsigned long msghashlen,
+                          int            hash_idx, unsigned long saltlen,
+                          int           *stat,     rsa_key      *key);
+\end{verbatim}
+
+This will RSA ``verify'' the signature in ``sig'' of length ``siglen''.  Next the RSA decoded data is PSS decoded
+and the extracted hash is compared against the message hash ``msghash'' of length ``msghashlen''.
+
+If the RSA decoded data is not a valid PSS message or if the PSS decoded hash does not match the ``msghash'' 
+the value ``res'' is set to $0$.  Otherwise, if the function succeeds and signature is valid ``res'' is set
+to $1$.
+
+\begin{verbatim}
+#include <tomcrypt.h>
+int main(void)
+{
+   int           err, hash_idx, prng_idx, res;

+\chapter{Diffie-Hellman Key Exchange}
+
+\section{Background}
+
+Diffie-Hellman was the original public key system proposed.  The system is based upon the group structure
+of finite fields.  For Diffie-Hellman a prime $p$ is chosen and a ``base'' $b$ such that $b^x\mbox{ }(\mbox{mod }p)$ 
+generates a large sub-group of prime order (for unique values of $x$).
+
+A secret key is an exponent $x$ and a public key is the value of $y \equiv g^x\mbox{ }(\mbox{mod }p)$.  The term
+``discrete logarithm'' denotes the action of finding $x$ given only $y$, $g$ and $p$.  The key exchange part of
+Diffie-Hellman arises from the fact that two users A and B with keys $(A_x, A_y)$ and $(B_x, B_y)$ can exchange 
+a shared key $K \equiv B_y^{A_x} \equiv A_y^{B_x} \equiv g^{A_xB_x}\mbox{ }(\mbox{mod }p)$.
+
+From this public encryption and signatures can be developed.  The trivial way to encrypt (for example) using a public key 
+$y$ is to perform the key exchange offline.  The sender invents a key $k$ and its public copy 
+$k' \equiv g^k\mbox{ }(\mbox{mod }p)$ and uses $K \equiv k'^{A_x}\mbox{ }(\mbox{mod }p)$ as a key to encrypt
+the message with.  Typically $K$ would be sent to a one-way hash and the message digested used as a key in a 
+symmetric cipher.
+
+It is important that the order of the sub-group that $g$ generates not only be large but also prime.  There are
+discrete logarithm algorithms that take $\sqrt r$ time given the order $r$.  The discrete logarithm can be computed
+modulo each prime factor of $r$ and the results combined using the Chinese Remainder Theorem.  In the cases where 
+$r$ is ``B-Smooth'' (e.g. all small factors or powers of small prime factors) the solution is trivial to find.
+
+To thwart such attacks the primes and bases in the library have been designed and fixed.  Given a prime $p$ the order of
+ the sub-group generated is a large prime namely ${p - 1} \over 2$.  Such primes are known as ``strong primes'' and the 
+smaller prime (e.g. the order of the base) are known as Sophie-Germaine primes.
+
+\section{Core Functions}
+
+This library also provides core Diffie-Hellman functions so you can negotiate keys over insecure mediums.  The routines 
+provided are relatively easy to use and only take two function calls to negotiate a shared key.  There is a structure
+called ``dh\_key'' which stores the Diffie-Hellman key in a format these routines can use.  The first routine is to
+make a Diffie-Hellman private key pair:
+\index{dh\_make\_key()}
+\begin{verbatim}
+int dh_make_key(prng_state *prng, int wprng, 
+                int keysize, dh_key *key);
+\end{verbatim}
+The ``keysize'' is the size of the modulus you want in bytes.  Currently support sizes are 96 to 512 bytes which correspond 
+to key sizes of 768 to 4096 bits. The smaller the key the faster it is to use however it will be less secure.  When 
+specifying a size not explicitly supported by the library it will round {\em up} to the next key size.  If the size is 
+above 512 it will return an error.  So if you pass ``keysize == 32'' it will use a 768 bit key but if you pass 
+``keysize == 20000'' it will return an error.  The primes and generators used are built-into the library and were designed 
+to meet very specific goals.  The primes are strong primes which means that if $p$ is the prime then
+$p-1$ is equal to $2r$ where $r$ is a large prime.  The bases are chosen to generate a group of order $r$ to prevent
+leaking a bit of the key.  This means the bases generate a very large prime order group which is good to make cryptanalysis
+hard.
+
+The next two routines are for exporting/importing Diffie-Hellman keys in a binary format.  This is useful for transport
+over communication mediums.  
+
+\index{dh\_export()} \index{dh\_import()}
+\begin{verbatim}
+int dh_export(unsigned char *out, unsigned long *outlen, 
+              int type, dh_key *key);
+
+int dh_import(const unsigned char *in, unsigned long inlen, dh_key *key);
+\end{verbatim}
+
+These two functions work just like the ``rsa\_export()'' and ``rsa\_import()'' functions except these work with 
+Diffie-Hellman keys. Its important to note you do not have to free the ram for a ``dh\_key'' if an import fails.  You can free a 
+``dh\_key'' using:
+\begin{verbatim}
+void dh_free(dh_key *key);
+\end{verbatim}
+After you have exported a copy of your public key (using {\bf PK\_PUBLIC} as ``type'') you can now create a shared secret 
+with the other user using:
+\index{dh\_shared\_secret()}
+\begin{verbatim}
+int dh_shared_secret(dh_key *private_key, 
+                     dh_key *public_key, 
+                     unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+
+Where ``private\_key'' is the key you made and ``public\_key'' is the copy of the public key the other user sent you.  The result goes
+into ``out'' and the length into ``outlen''.  If all went correctly the data in ``out'' should be identical for both parties.  It is important to
+note that the two keys have to be the same size in order for this to work.  There is a function to get the size of a
+key:
+\index{dh\_get\_size()}
+\begin{verbatim}
+int dh_get_size(dh_key *key);
+\end{verbatim}
+This returns the size in bytes of the modulus chosen for that key.

+\subsection{Remarks on Usage}
+Its important that you hash the shared key before trying to use it as a key for a symmetric cipher or something.  An 
+example program that communicates over sockets, using MD5 and 1024-bit DH keys is\footnote{This function is a small example.  It is suggested that proper packaging be used.  For example, if the public key sent is truncated these routines will not detect that.}:
+\newpage
+\begin{small}
+\begin{verbatim}
+int establish_secure_socket(int sock, int mode, unsigned char *key, 
+                            prng_state *prng, int wprng)
+{
+   unsigned char buf[4096], buf2[4096];
+   unsigned long x, len;
+   int res, err, inlen;
+   dh_key mykey, theirkey;
+
+   /* make up our private key */
+   if ((err = dh_make_key(prng, wprng, 128, &mykey)) != CRYPT_OK)  {
+      return err;
+   }
+
+   /* export our key as public */ 
+   x = sizeof(buf);
+   if ((err = dh_export(buf, &x, PK_PUBLIC, &mykey)) != CRYPT_OK) {
+      res = err;
+      goto done2;
+   }
+
+   if (mode == 0) {
+      /* mode 0 so we send first */
+      if (send(sock, buf, x, 0) != x) {
+         res = CRYPT_ERROR;

+      if ((inlen = recv(sock, buf2, sizeof(buf2), 0)) <= 0) {

+         goto done2;
+      }
+   }
+
+   if ((err = dh_import(buf2, inlen, &theirkey)) != CRYPT_OK) { 
+      res = err;
+      goto done2;
+   }
+
+   /* make shared secret */
+   x = sizeof(buf);
+   if ((err = dh_shared_secret(&mykey, &theirkey, buf, &x)) != CRYPT_OK) {
+      res = err;
+      goto done;
+   }
+ 
+   /* hash it */
+   len = 16;        /* default is MD5 so "key" must be at least 16 bytes long */
+   if ((err = hash_memory(find_hash("md5"), buf, x, key, &len)) != CRYPT_OK) {

+\end{verbatim}

+\subsection{Remarks on The Snippet}
+When the above code snippet is done (assuming all went well) their will be a shared 128-bit key in the ``key'' array
+passed to ``establish\_secure\_socket()''.
+
+\section{Other Diffie-Hellman Functions}
+In order to test the Diffie-Hellman function internal workings (e.g. the primes and bases) their is a test function made
+available:
+\index{dh\_test()}
+\begin{verbatim}
+int dh_test(void);
+\end{verbatim}
+
+This function returns {\bf CRYPT\_OK} if the bases and primes in the library are correct.  There is one last helper 
+function:
+\index{dh\_sizes()}
+\begin{verbatim}
+void dh_sizes(int *low, int *high);
+\end{verbatim}
+Which stores the smallest and largest key sizes support into the two variables.
+
+\section{DH Packet}
+Similar to the RSA related functions there are functions to encrypt or decrypt symmetric keys using the DH public key
+algorithms.  
+\index{dh\_encrypt\_key()} \index{dh\_decrypt\_key()}
+\begin{verbatim}
+int dh_encrypt_key(const unsigned char *in,   unsigned long  inlen,
+                         unsigned char *out,  unsigned long *len, 
+                         prng_state *prng, int wprng, int hash, 
+                         dh_key *key);
+
+int dh_decrypt_key(const unsigned char *in,  unsigned long  inlen,
+                         unsigned char *out, unsigned long *outlen, 
+                         dh_key *key);
+\end{verbatim}
+Where ``in'' is an input symmetric key of no more than 32 bytes.  Essentially these routines created a random public key
+and find the hash of the shared secret.  The message digest is than XOR'ed against the symmetric key.  All of the 
+required data is placed in ``out'' by ``dh\_encrypt\_key()''.   The hash must produce a message digest at least as large
+as the symmetric key you are trying to share.
+
+Similar to the RSA system you can sign and verify a hash of a message.
+\index{dh\_sign\_hash()} \index{dh\_verify\_hash()}
+\begin{verbatim}
+int dh_sign_hash(const unsigned char *in,  unsigned long inlen,
+                       unsigned char *out, unsigned long *outlen,
+                       prng_state *prng, int wprng, dh_key *key);
+
+int dh_verify_hash(const unsigned char *sig, unsigned long siglen,
+                         const unsigned char *hash, unsigned long hashlen, 
+                         int *stat, dh_key *key);
+\end{verbatim}
+
+The ``dh\_sign\_hash'' function signs the message hash in ``in'' of length ``inlen'' and forms a DH packet in ``out''.  
+The ``dh\_verify\_hash'' function verifies the DH signature in ``sig'' against the hash in ``hash''.  It sets ``stat''
+to non-zero if the signature passes or zero if it fails.
+
+\chapter{Elliptic Curve Cryptography}
+
+\section{Background}
+The library provides a set of core ECC functions as well that are designed to be the Elliptic Curve analogy of all of the 
+Diffie-Hellman routines in the previous chapter.  Elliptic curves (of certain forms) have the benefit that they are harder
+to attack (no sub-exponential attacks exist unlike normal DH crypto) in fact the fastest attack requires the square root
+of the order of the base point in time.  That means if you use a base point of order $2^{192}$ (which would represent a
+192-bit key) then the work factor is $2^{96}$ in order to find the secret key.
+
+The curves in this library are taken from the following website:
+\begin{verbatim}
+http://csrc.nist.gov/cryptval/dss.htm
+\end{verbatim}
+
+They are all curves over the integers modulo a prime.  The curves have the basic equation that is:
+\begin{equation}
+y^2 = x^3 - 3x + b\mbox{ }(\mbox{mod }p)
+\end{equation}
+
+The variable $b$ is chosen such that the number of points is nearly maximal.  In fact the order of the base points $\beta$ 
+provided are very close to $p$ that is $\vert \vert \phi(\beta) \vert \vert \approx \vert \vert p \vert \vert$.  The curves
+range in order from $\approx 2^{192}$ points to $\approx 2^{521}$.  According to the source document any key size greater
+than or equal to 256-bits is sufficient for long term security.  
+
+\section{Key Format}
+LibTomCrypt uses it's own format for ECC public and private keys.  While ANSI X9.62 partially specifies key formats (it covers public keys) it does it in a less
+than ideally simple manner.  In the case of LibTomCrypt it is meant \textbf{solely} for NIST $GF(p)$ curves.  The format of the keys is as follows:
+
+\begin{small}
+\begin{verbatim}
+ECCPublicKey ::= SEQUENCE {
+    flags       BIT STRING(1), -- public/private flag (always zero), 
+    keySize     INTEGER,       -- Curve size (in bits) divided by eight 
+                               -- and rounded down, e.g. 521 => 65
+    pubkey.x    INTEGER,       -- The X co-ordinate of the public key point
+    pubkey.y    INTEGER,       -- The Y co-ordinate of the public key point
+}
+
+ECCPrivateKey ::= SEQUENCE {
+    flags       BIT STRING(1), -- public/private flag (always one), 
+    keySize     INTEGER,       -- Curve size (in bits) divided by eight 
+                               -- and rounded down, e.g. 521 => 65
+    pubkey.x    INTEGER,       -- The X co-ordinate of the public key point
+    pubkey.y    INTEGER,       -- The Y co-ordinate of the public key point
+    secret.k    INTEGER,       -- The secret key scalar
+}
+\end{verbatim}
+\end{small}
+
+The first flags bit denotes whether the key is public (zero) or private (one).  
+
+\section{Core Functions}
+
+Like the DH routines there is a key structure ``ecc\_key'' used by the functions.  There is a function to make a key:
+\index{ecc\_make\_key()}
+\begin{verbatim}
+int ecc_make_key(prng_state *prng, int wprng, 
+                 int keysize, ecc_key *key);
+\end{verbatim}
+
+The ``keysize'' is the size of the modulus in bytes desired.  Currently directly supported values are 24, 28, 32, 48 and 65 bytes which
+correspond to key sizes of 192, 224, 256, 384 and 521 bits respectively.  If you pass a key size that is between any key size
+it will round the keysize up to the next available one.  The rest of the parameters work like they do in the ``dh\_make\_key()'' function.  
+To free the ram allocated by a key call:
+\index{ecc\_free()}
+\begin{verbatim}
+void ecc_free(ecc_key *key);
+\end{verbatim}
+
+To import and export a key there are: 
+\index{ecc\_export()}
+\index{ecc\_import()}
+\begin{verbatim}
+int ecc_export(unsigned char *out, unsigned long *outlen, 
+               int type, ecc_key *key);
+
+int ecc_import(const unsigned char *in, unsigned long inlen, ecc_key *key);
+\end{verbatim}
+These two work exactly like there DH counterparts.  Finally when you share your public key you can make a shared secret
+with:
+\index{ecc\_shared\_secret()}
+\begin{verbatim}
+int ecc_shared_secret(ecc_key *private_key, 
+                      ecc_key *public_key, 
+                      unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+Which works exactly like the DH counterpart, the ``private\_key'' is your own key and ``public\_key'' is the key the other
+user sent you.   Note that this function stores both $x$ and $y$ co-ordinates of the shared
+elliptic point.  You should hash the output to get a shared key in a more compact and useful form (most of the entropy is 
+in $x$ anyways).  Both keys have to be the same size for this to work, to help there is a function to get the size in bytes
+ of a key.
+\index{ecc\_get\_size()}
+\begin{verbatim}
+int ecc_get_size(ecc_key *key);
+\end{verbatim}
+
+To test the ECC routines and to get the minimum and maximum key sizes there are these two functions:
+\index{ecc\_test()}
+\begin{verbatim}
+int ecc_test(void);
+void ecc_sizes(int *low, int *high);
+\end{verbatim}
+Which both work like their DH counterparts.
+
+\section{ECC Packet}
+Similar to the RSA API there are two functions which encrypt and decrypt symmetric keys using the ECC public key
+algorithms.
+
+\index{ecc\_encrypt\_key()} \index{ecc\_decrypt\_key()}
+\begin{verbatim}
+int ecc_encrypt_key(const unsigned char *in,   unsigned long  inlen,
+                          unsigned char *out,  unsigned long *outlen, 
+                          prng_state *prng, int wprng, int hash, 
+                          ecc_key *key);
+
+int ecc_decrypt_key(const unsigned char *in,  unsigned long  inlen,
+                          unsigned char *out, unsigned long *outlen, 
+                          ecc_key *key);
+\end{verbatim}
+
+Where ``in'' is an input symmetric key of no more than 64 bytes.  Essentially these routines created a random public key
+and find the hash of the shared secret.  The message digest is than XOR'ed against the symmetric key.  All of the required
+data is placed in ``out'' by ``ecc\_encrypt\_key()''.   The hash chosen must produce a message digest at least as large
+as the symmetric key you are trying to share.
+
+\subsection{Encrypt Packet Format}
+
+The packet format for the encrypted keys is the following ASN.1 SEQUENCE:
+
+\begin{verbatim}
+ECCEncrypt ::= SEQUENCE {
+   hashID        OBJECT IDENTIFIER, -- OID of hash used
+   pubkey        OCTET STRING     , -- Encapsulated ECCPublicKey (see above)
+   skey          OCTET STRING       -- xor of plaintext and "hash of shared secret"
+}
+\end{verbatim}
+
+There are also functions to sign and verify the hash of a message.
+\index{ecc\_sign\_hash()} \index{ecc\_verify\_hash()}
+\begin{verbatim}
+int ecc_sign_hash(const unsigned char *in,  unsigned long inlen,
+                        unsigned char *out, unsigned long *outlen,
+                        prng_state *prng, int wprng, ecc_key *key);
+
+int ecc_verify_hash(const unsigned char *sig, unsigned long siglen,
+                    const unsigned char *hash, unsigned long hashlen, 
+                          int *stat, ecc_key *key);
+\end{verbatim}
+
+The ``ecc\_sign\_hash'' function signs the message hash in ``in'' of length ``inlen'' and forms a ECC packet in ``out''.  
+The ``ecc\_verify\_hash'' function verifies the ECC signature in ``sig'' against the hash in ``hash''.  It sets ``stat''
+to non-zero if the signature passes or zero if it fails.
+
+\subsection{Signature Format}
+The signature code is an implementation of X9.62 EC-DSA and the output is comformant for GF(p) curves.
+
+\section{ECC Keysizes}
+With ECC if you try and sign a hash that is bigger than your ECC key you can run into problems.  The math will still work
+and in effect the signature will still work.  With ECC keys the strength of the signature is limited by the size of
+the hash or the size of they key, whichever is smaller.  For example, if you sign with SHA256 and an ECC-192 key in effect
+you have 192-bits of security.  
+
+The library will not warn you if you make this mistake so it is important to check yourself before using the 
+signatures.
+
+\chapter{Digital Signature Algorithm}
+\section{Introduction}
+The Digital Signature Algorithm (or DSA) is a variant of the ElGamal Signature scheme which has been modified to 
+reduce the bandwidth of a signature.  For example, to have ``80-bits of security'' with ElGamal you need a group of 
+order at least 1024-bits.  With DSA you need a group of order at least 160-bits.  By comparison the ElGamal signature
+would require at least 256 bytes where as the DSA signature would require only at least 40 bytes.  
+
+The API for the DSA is essentially the same as the other PK algorithms.  Except in the case of DSA no encryption or
+decryption routines are provided.  
+
+\section{Key Format}
+Since no useful public standard for DSA key storage was presented to me during the course of this development I made my own ASN.1 SEQUENCE which I document
+now so that others can interoperate with this library.
+
+\begin{verbatim}
+DSAPublicKey ::= SEQUENCE {
+    publicFlags    BIT STRING(1), -- must be 0
+    g              INTEGER      , -- base generator, check that g^q mod p == 1
+                                  -- and that 1 < g < p - 1
+    p              INTEGER      , -- prime modulus 
+    q              INTEGER      , -- order of sub-group (must be prime)
+    y              INTEGER      , -- public key, specifically, g^x mod p, 
+                                  -- check that y^q mod p == 1
+                                  -- and that 1 < y < p - 1
+}
+
+DSAPrivateKey ::= SEQUENCE {
+    publicFlags    BIT STRING(1), -- must be 1
+    g              INTEGER      , -- base generator, check that g^q mod p == 1
+                                  -- and that 1 < g < p - 1
+    p              INTEGER      , -- prime modulus 
+    q              INTEGER      , -- order of sub-group (must be prime)
+    y              INTEGER      , -- public key, specifically, g^x mod p, 
+                                  -- check that y^q mod p == 1
+                                  -- and that 1 < y < p - 1
+    x              INTEGER        -- private key
+}
+\end{verbatim}
+
+The leading BIT STRING has a single bit in it which is zero for public keys and one for private keys.  This makes the structure uniquely decodable and easy
+to work with.
+
+\section{Key Generation}
+To make a DSA key you must call the following function
+\begin{verbatim}
+int dsa_make_key(prng_state *prng, int wprng, 
+                 int group_size, int modulus_size, 
+                 dsa_key *key);
+\end{verbatim}
+The variable ``prng'' is an active PRNG state and ``wprng'' the index to the descriptor.  ``group\_size'' and 
+``modulus\_size'' control the difficulty of forging a signature.  Both parameters are in bytes.  The larger the
+``group\_size'' the more difficult a forgery becomes upto a limit.  The value of $group\_size$ is limited by 
+$15 < group\_size < 1024$ and $modulus\_size - group\_size < 512$.  Suggested values for the pairs are as follows.
+
+\begin{center}
+\begin{tabular}{|c|c|c|}
+\hline \textbf{Bits of Security} & \textbf{group\_size} & \textbf{modulus\_size} \\
+\hline 80  & 20 & 128 \\
+\hline 120 & 30 & 256 \\
+\hline 140 & 35 & 384 \\
+\hline 160 & 40 & 512 \\
+\hline
+\end{tabular}
+\end{center}
+
+When you are finished with a DSA key you can call the following function to free the memory used.
+\index{dsa\_free()}
+\begin{verbatim}
+void dsa_free(dsa_key *key);
+\end{verbatim}
+
+\section{Key Verification}
+Each DSA key is composed of the following variables.
+
+\begin{enumerate}
+  \item $q$ a small prime of magnitude $256^{group\_size}$.  
+  \item $p = qr + 1$ a large prime of magnitude $256^{modulus\_size}$ where $r$ is a random even integer.
+  \item $g = h^r \mbox{ (mod }p\mbox{)}$ a generator of order $q$ modulo $p$.  $h$ can be any non-trivial random 
+        value.  For this library they start at $h = 2$ and step until $g$ is not $1$.
+  \item $x$ a random secret (the secret key) in the range $1 < x < q$ 
+  \item $y = g^x \mbox{ (mod }p\mbox{)}$ the public key.
+\end{enumerate}
+
+A DSA key is considered valid if it passes all of the following tests.
+
+\begin{enumerate}
+   \item $q$ must be prime.
+   \item $p$ must be prime.
+   \item $g$ cannot be one of $\lbrace -1, 0, 1 \rbrace$ (modulo $p$).
+   \item $g$ must be less than $p$.
+   \item $(p-1) \equiv 0 \mbox{ (mod }q\mbox{)}$.
+   \item $g^q \equiv 1 \mbox{ (mod }p\mbox{)}$.
+   \item $1 < y < p - 1$
+   \item $y^q \equiv 1 \mbox{ (mod }p\mbox{)}$.
+\end{enumerate}
+
+Tests one and two ensure that the values will at least form a field which is required for the signatures to  
+function.  Tests three and four ensure that the generator $g$ is not set to a trivial value which would make signature
+forgery easier.  Test five ensures that $q$ divides the order of multiplicative sub-group of $\Z/p\Z$. Test six
+ensures that the generator actually generates a prime order group.  Tests seven and eight ensure that the public key
+is within range and belongs to a group of prime order.  Note that test eight does not prove that $g$ generated $y$ only
+that $y$ belongs to a multiplicative sub-group of order $q$. 
+
+The following function will perform these tests.
+
+\index{dsa\_verify\_key()}
+\begin{verbatim}
+int dsa_verify_key(dsa_key *key, int *stat);
+\end{verbatim}
+
+This will test ``key'' and store the result in ``stat''.  If the result is $stat = 0$ the DSA key failed one of the tests
+and should not be used at all.  If the result is $stat = 1$ the DSA key is valid (as far as valid mathematics are concerned).
+
+\section{Signatures}
+To generate a DSA signature call the following function
+
+\index{dsa\_sign\_hash()}
+\begin{verbatim}
+int dsa_sign_hash(const unsigned char *in,  unsigned long inlen,
+                        unsigned char *out, unsigned long *outlen,
+                        prng_state *prng, int wprng, dsa_key *key);
+\end{verbatim}
+
+Which will sign the data in ``in'' of length ``inlen'' bytes.  The signature is stored in ``out'' and the size
+of the signature in ``outlen''.  If the signature is longer than the size you initially specify in ``outlen'' nothing
+is stored and the function returns an error code.  The DSA ``key'' must be of the \textbf{PK\_PRIVATE} persuasion.
+
+To verify a hash created with that function use the following function
+
+\index{dsa\_verify\_hash()} 
+\begin{verbatim}
+int dsa_verify_hash(const unsigned char *sig, unsigned long siglen,
+                    const unsigned char *hash, unsigned long inlen, 
+                    int *stat, dsa_key *key);
+\end{verbatim}
+Which will verify the data in ``hash'' of length ``inlen'' against the signature stored in ``sig'' of length ``siglen''.  
+It will set ``stat'' to $1$ if the signature is valid, otherwise it sets ``stat'' to $0$.  
+
+\section{Import and Export}
+
+To export a DSA key so that it can be transported use the following function
+\index{dsa\_export()}
+\begin{verbatim}
+int dsa_export(unsigned char *out, unsigned long *outlen, 
+               int type, 
+               dsa_key *key);
+\end{verbatim}
+This will export the DSA ``key'' to the buffer ``out'' and set the length in ``outlen'' (which must have been previously
+initialized to the maximum buffer size).  The ``type`` variable may be either \textbf{PK\_PRIVATE} or \textbf{PK\_PUBLIC}
+depending on whether you want to export a private or public copy of the DSA key.
+
+To import an exported DSA key use the following function
+
+\index{dsa\_import()}
+\begin{verbatim}
+int dsa_import(const unsigned char *in, unsigned long inlen, 
+               dsa_key *key);
+\end{verbatim}
+
+This will import the DSA key from the buffer ``in'' of length ``inlen'' to the ``key''.  If the process fails the function
+will automatically free all of the heap allocated in the process (you don't have to call dsa\_free()).

+\section{ASN.1 Formats}
+LibTomCrypt supports a variety of ASN.1 data types encoded with the Distinguished Encoding Rules (DER) suitable for various cryptographic protocols.  The data types
+are all provided with three basic functions with \textit{similar} prototypes.  One function has been dedicated to calculate the length in octets of a given
+format and two functions have been dedicated to encoding and decoding the format.  
+
+On top of the basic data types are the SEQUENCE and\footnote{Planned for LTC 1.06} SET data types which are collections of other ASN.1 types.  They are provided 
+in the same manner as the other data types except they use list of objects known as the \textbf{ltc\_asn1\_list} structure.  It is defined as 
+
+\index{ltc\_asn1\_list structure}
+\begin{verbatim}
+typedef struct {
+   int           type;
+   void         *data;
+   unsigned long size;
+   int           used;
+} ltc_asn1_list;
+\end{verbatim}
+
+The ``type'' field is one of the following ASN.1 field definitions.  The ``data'' pointer is a void pointer to the data to be encoded (or the destination) and the 
+``size'' field is specific to what you are encoding (e.g. number of bits in the BIT STRING data type).  The ``used'' field is primarily for the CHOICE decoder
+and reflects if the particular member of a list was the decoded data type.  To help build the lists in an orderly fashion the macro
+``LTC\_SET\_ASN1(list, index, Type, Data, Size)'' has been provided.
+
+It will assign to the ``index''th position in the ``list'' the tripplet (Type, Data, Size).  An example usage would be:
+
+\begin{small}
+\begin{verbatim}
+...
+ltc_asn1_list   sequence[3];
+unsigned long   three=3;
+
+LTC_SET_ASN1(sequence, 0, LTC_ASN1_IA5_STRING,    "hello", 5);
+LTC_SET_ASN1(sequence, 1, LTC_ASN1_SHORT_INTEGER, &three,  1);
+LTC_SET_ASN1(sequence, 2, LTC_ASN1_NULL,           NULL,   0);
+\end{verbatim}
+\end{small}
+
+The macro is relatively safe with respect to modifying variables, for instance the following code is equivalent.
+
+\begin{small}
+\begin{verbatim}
+...
+ltc_asn1_list   sequence[3];
+unsigned long   three=3;
+int             x=0;
+LTC_SET_ASN1(sequence, x++, LTC_ASN1_IA5_STRING,    "hello", 5);
+LTC_SET_ASN1(sequence, x++, LTC_ASN1_SHORT_INTEGER, &three,  1);
+LTC_SET_ASN1(sequence, x++, LTC_ASN1_NULL,           NULL,   0);
+\end{verbatim}
+\end{small}

+\subsection{SEQUENCE Type}
+The SEQUENCE data type is a collection of other ASN.1 data types encapsulated with a small header which is a useful way of sending multiple data types in one packet.
+
+\subsubsection{SEUQNECE Encoding}
+To encode a sequence a \textbf{ltc\_asn1\_list} array must be initialized with the members of the sequence and their respective pointers.  The encoding is performed
+with the following function.
+
+\index{der\_encode\_sequence()}
+\begin{verbatim}
+int der_encode_sequence(ltc_asn1_list *list, unsigned long inlen,
+                        unsigned char *out,  unsigned long *outlen);
+\end{verbatim}
+This encodes a sequence of items pointed to by ``list'' where the list has ``inlen'' items in it.  The SEQUENCE will be encoded to ``out'' and of length ``outlen''.  The
+function will terminate when it reads all the items out of the list (upto ``inlen'') or it encounters an item in the list with a type of \textbf{LTC\_ASN1\_EOL}.
+
+The ``data'' pointer in the list would be the same pointer you would pass to the respective ASN.1 encoder (e.g. der\_encode\_bit\_string()) and it is simply passed on
+verbatim to the dependent encoder.  The list can contain other SEQUENCE or SET types which enables you to have nested SEQUENCE and SET definitions.  In these cases
+the ``data'' pointer is simply a pointer to another \textbf{ltc\_asn1\_list}.
+
+\subsubsection{SEQUENCE Decoding}
+
+\index{der\_decode\_sequence()}
+
+Decoding a SEQUENCE is similar to encoding.  You set up an array of \textbf{ltc\_asn1\_list} where in this case the ``size'' member is the maximum size 
+(in certain cases).  For types such as IA5 STRING, BIT STRING, OCTET STRING (etc) the ``size'' field is updated after successful decoding to reflect how many
+units of the respective type has been loaded.  
+
+\begin{verbatim}
+int der_decode_sequence(const unsigned char *in,   unsigned long  inlen,
+                              ltc_asn1_list *list, unsigned long  outlen);
+\end{verbatim}
+
+This will decode upto ``outlen'' items from the input buffer ``in'' of length ``inlen'' octets.  The function will stop (gracefully) when it runs out of items to decode.
+It will fail (for among other reasons) when it runs out of input bytes to read, a data type is invalid or a heap failure occured.
+
+For the following types the ``size'' field will be updated to reflect the number of units read of the given type.
+\begin{enumerate}
+   \item BIT STRING
+   \item OCTET STRING
+   \item OBJECT IDENTIFIER
+   \item IA5 STRING
+   \item PRINTABLE STRING
+\end{enumerate}
+
+\subsubsection{SEQUENCE Length}
+
+The length of a SEQUENCE can be determined with the following function.
+
+\index{der\_length\_sequence()}
+\begin{verbatim}
+int der_length_sequence(ltc_asn1_list *list, unsigned long inlen,
+                        unsigned long *outlen);
+\end{verbatim}
+
+This will get the encoding size for the given ``list'' of length ``inlen'' and store it in ``outlen''.  
+
+\subsubsection{SEQUENCE Multiple Argument Lists}
+
+For small or simple sequences an encoding or decoding can be performed with one of the following two functions.
+
+\index{der\_encode\_sequence\_multi()}
+\index{der\_decode\_sequence\_multi()}
+
+\begin{verbatim}
+int der_encode_sequence_multi(unsigned char *out, unsigned long *outlen, ...);
+int der_decode_sequence_multi(const unsigned char *in, unsigned long inlen, ...);
+\end{verbatim}
+
+These either encode or decode (respectively) a SEQUENCE data type where the items in the sequence are specified after the length parameter.
+
+The list of items are specified as a triple of the form ``(type, size, data)''  where ``type'' is an \textbf{int}, ``size'' is a \textbf{unsigned long}
+and ``data'' is \textbf{void} pointer.  The list of items must be terminated with an item with the type \textbf{LTC\_ASN1\_EOL}.
+
+It's ideal that you cast the ``size'' values to unsigned long to ensure that the proper data type is passed to the function.  Constants such as ``1'' without
+a cast or prototype are of type \textbf{int} by default.  Appending \textit{UL} or prepending \textit{(unsigned long)} is enough to cast it to the correct type.
+
+\subsection{ASN.1 INTEGER}
+
+To encode or decode INTEGER data types use the following functions.
+
+\index{der\_encode\_integer()}
+\index{der\_decode\_integer()}
+\index{der\_length\_integer()}
+\begin{verbatim}
+int der_encode_integer(mp_int *num, unsigned char *out, unsigned long *outlen);
+int der_decode_integer(const unsigned char *in, unsigned long inlen, mp_int *num);
+int der_length_integer(mp_int *num, unsigned long *len);
+\end{verbatim}
+
+These will encode or decode a signed INTEGER data type using the ``mp\_int'' data type to store the large INTEGER.  To encode smaller values without allocating
+an mp\_int to store the value the ``short'' INTEGER functions were made available.
+
+\index{der\_encode\_short\_integer()}
+\index{der\_decode\_short\_integer()}
+\index{der\_length\_short\_integer()}
+\begin{verbatim}
+int der_encode_short_integer(unsigned long  num, 
+                             unsigned char *out, unsigned long *outlen);
+
+int der_decode_short_integer(const unsigned char *in,  unsigned long inlen, 
+                                   unsigned long *num);
+
+int der_length_short_integer(unsigned long num, unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an unsigned \textbf{unsigned long} type (only reads upto 32--bits).  For values in the range $0 \dots 2^{32} - 1$ the integer 
+and short integer functions can encode and decode each others outputs.  
+
+\subsection{ASN.1 BIT STRING}
+
+\index{der\_encode\_bit\_string()}
+\index{der\_decode\_bit\_string()}
+\index{der\_length\_bit\_string()}
+\begin{verbatim}
+int der_encode_bit_string(const unsigned char *in, unsigned long inlen,
+                                unsigned char *out, unsigned long *outlen);
+
+int der_decode_bit_string(const unsigned char *in, unsigned long inlen,
+                                unsigned char *out, unsigned long *outlen);
+
+int der_length_bit_string(unsigned long nbits, unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode a BIT STRING data type.  The bits are passed in (or read out) using one \textbf{char} per bit.  A non--zero value will be interpretted
+as a one bit and a zero value a zero bit.
+
+\subsection{ASN.1 OCTET STRING}
+
+\index{der\_encode\_octet\_string()}
+\index{der\_decode\_octet\_string()}
+\index{der\_length\_octet\_string()}
+\begin{verbatim}
+int der_encode_octet_string(const unsigned char *in, unsigned long inlen,
+                                  unsigned char *out, unsigned long *outlen);
+
+int der_decode_octet_string(const unsigned char *in, unsigned long inlen,
+                                  unsigned char *out, unsigned long *outlen);
+
+int der_length_octet_string(unsigned long noctets, unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an OCTET STRING data type.  The octets are stored using one \textbf{char} each.  
+
+\subsection{ASN.1 OBJECT IDENTIFIER}
+
+\index{der\_encode\_object\_identifier()}
+\index{der\_decode\_object\_identifier()}
+\index{der\_length\_object\_identifier()}
+\begin{verbatim}
+int der_encode_object_identifier(unsigned long *words, unsigned long  nwords,
+                                 unsigned char *out,   unsigned long *outlen);
+
+int der_decode_object_identifier(const unsigned char *in,    unsigned long  inlen,
+                                       unsigned long *words, unsigned long *outlen);
+
+int der_length_object_identifier(unsigned long *words, unsigned long nwords, 
+                                 unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an OBJECT IDENTIFIER object.  The words of the OID are stored in individual \textbf{unsigned long} elements and must be in the range
+$0 \ldots 2^{32} - 1$.  
+
+\subsection{ASN.1 IA5 STRING}
+
+\index{der\_encode\_ia5\_string()}
+\index{der\_decode\_ia5\_string()}
+\index{der\_length\_ia5\_string()}
+\begin{verbatim}
+int der_encode_ia5_string(const unsigned char *in, unsigned long inlen,
+                                unsigned char *out, unsigned long *outlen);
+
+int der_decode_ia5_string(const unsigned char *in, unsigned long inlen,
+                                unsigned char *out, unsigned long *outlen);
+
+int der_length_ia5_string(const unsigned char *octets, unsigned long noctets, 
+                                unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an IA5 STRING.  The characters are read or stored in individual \textbf{char} elements.  This functions performs internal character
+to numerical conversions based on the conventions of the compiler being used.  For instance, on an x86\_32 machine 'A' == 65 but the same may not be true on 
+say a SPARC machine.  Internally these functions have a table of literal characters and their numerical ASCII values.  This provides a stable conversion provided
+that the build platform honours the runtime platforms character conventions.
+
+If you're worried try building the test suite and running it.  It has hard coded test vectors to ensure it is operating properly. 
+
+\subsection{ASN.1 PRINTABLE STRING}
+
+\index{der\_encode\_printable\_string()}
+\index{der\_decode\_printable\_string()}
+\index{der\_length\_printable\_string()}
+\begin{verbatim}
+int der_encode_printable_string(const unsigned char *in, unsigned long inlen,
+                                unsigned char *out, unsigned long *outlen);
+
+int der_decode_printable_string(const unsigned char *in, unsigned long inlen,
+                                unsigned char *out, unsigned long *outlen);
+
+int der_length_printable_string(const unsigned char *octets, unsigned long noctets, 
+                                unsigned long *outlen);
+\end{verbatim}
+
+These will encode or decode an PRINTABLE STRING.  The characters are read or stored in individual \textbf{char} elements.  This functions performs internal character
+to numerical conversions based on the conventions of the compiler being used.  For instance, on an x86\_32 machine 'A' == 65 but the same may not be true on 
+say a SPARC machine.  Internally these functions have a table of literal characters and their numerical ASCII values.  This provides a stable conversion provided
+that the build platform honours the runtime platforms character conventions.
+
+If you're worried try building the test suite and running it.  It has hard coded test vectors to ensure it is operating properly. 
+
+\subsection{ASN.1 UTCTIME}
+
+The UTCTIME type is to store a date and time in ASN.1 format.  It uses the following structure to organize the time.
+
+\begin{verbatim}
+typedef struct {
+   unsigned YY, /* year    00--99 */
+            MM, /* month   01--12 */
+            DD, /* day     01--31 */
+            hh, /* hour    00--23 */
+            mm, /* minute  00--59 */
+            ss, /* second  00--59 */
+            off_dir, /* timezone offset direction 0 == +, 1 == - */
+            off_hh, /* timezone offset hours */
+            off_mm; /* timezone offset minutes */
+} ltc_utctime;
+\end{verbatim}
+
+The time can be offset plus or minus a set amount of hours (off\_hh) and minutes (off\_mm).  When ``off\_dir'' is zero the time will be added otherwise it 
+will be subtracted.  
+
+For instance, the array $\lbrace 5, 6, 20, 22, 4, 00, 0, 5, 0 \rbrace$ represents the current time of 2005, June 20th, 22:04:00 with a time offset of +05h00.  
+
+\index{der\_encode\_utctime()}
+\index{der\_decode\_utctime()}
+\index{der\_length\_utctime()}
+\begin{verbatim}
+int der_encode_utctime(ltc_utctime *utctime, 
+                       unsigned char *out,   unsigned long *outlen);
+
+int der_decode_utctime(const unsigned char *in, unsigned long *inlen,
+                             ltc_utctime   *out);
+
+int der_length_utctime(ltc_utctime *utctime, unsigned long *outlen);
+\end{verbatim}
+
+The encoder will store time in one of the two ASN.1 formats, either ``YYMMDDhhmmssZ'' or ``YYMMDDhhmmss$\pm$hhmm'' and perform minimal error checking on the 
+input.  The decoder will read all valid ASN.1 formats and perform range checking on the values (not complete but rational) useful for catching packet errors.
+
+It is suggested that decoded data be further scrutinized (e.g. days of month in particular).
+
+\subsection{ASN.1 CHOICE}
+
+The CHOICE ASN.1 type represents a union of ASN.1 types all of which are stored in a ``ltc\_asn1\_list''.  There is no encoder for the CHOICE type, only a 
+decoder.  The decoder will scan through the provided list attempting to use the appropriate decoder on the input packet.  The list can contain any ASN.1 data
+type\footnote{Except it cannot have LTC\_ASN1\_INTEGER and LTC\_ASN1\_SHORT\_INTEGER simultaneously.} except for other CHOICE types.  
+
+There is no encoder for the CHOICE type as the actual DER encoding is the encoding of the chosen type.  
+
+\index{der\_decode\_choice()}
+\begin{verbatim}
+int der_decode_choice(const unsigned char *in,   unsigned long *inlen,
+                            ltc_asn1_list *list, unsigned long  outlen);
+\end{verbatim}
+
+This will decode the input in the ``in'' field of length ``inlen''.  It uses the provided ASN.1 list specified in the ``list'' field which has ``outlen'' elements.  
+The ``inlen'' field will be updated with the length of the decoded data type as well as the respective entry in the ``list'' field will have the ``used'' flag 
+set to non--zero to reflect it was the data type decoded.
+
+\section{Password Based Cryptography}
+\subsection{PKCS \#5}
+\index{PKCS \#5}
+In order to securely handle user passwords for the purposes of creating session keys and chaining IVs the PKCS \#5 was drafted.   PKCS \#5
+is made up of two algorithms, Algorithm One and Algorithm Two.  Algorithm One is the older fairly limited algorithm which has been implemented
+for completeness.  Algorithm Two is a bit more modern and more flexible to work with.
+
+\subsection{Algorithm One}
+Algorithm One accepts as input a password, an 8--byte salt and an iteration counter.  The iteration counter is meant to act as delay for
+people trying to brute force guess the password.  The higher the iteration counter the longer the delay.  This algorithm also requires a hash 
+algorithm and produces an output no longer than the output of the hash.  
+
+\index{pkcs\_5\_alg1()}
+\begin{alltt}
+int pkcs_5_alg1(const unsigned char *password, unsigned long password_len, 
+                const unsigned char *salt, 
+                int iteration_count,  int hash_idx,
+                unsigned char *out,   unsigned long *outlen)
+\end{alltt}
+Where ``password'' is the users password.  Since the algorithm allows binary passwords you must also specify the length in ``password\_len''.  
+The ``salt'' is a fixed size 8--byte array which should be random for each user and session.  The ``iteration\_count'' is the delay desired
+on the password.  The ``hash\_idx'' is the index of the hash you wish to use in the descriptor table.  
+
+The output of length upto ``outlen'' is stored in ``out''.  If ``outlen'' is initially larger than the size of the hash functions output
+it is set to the number of bytes stored.  If it is smaller than not all of the hash output is stored in ``out''.
+
+\subsection{Algorithm Two}
+
+Algorithm Two is the recommended algorithm for this task.  It allows variable length salts and can produce outputs larger than the 
+hash functions output.  As such it can easily be used to derive session keys for ciphers and MACs as well initial vectors as required
+from a single password and invokation of this algorithm.
+
+\index{pkcs\_5\_alg2()}
+\begin{alltt}
+int pkcs_5_alg2(const unsigned char *password, unsigned long password_len, 
+                const unsigned char *salt,     unsigned long salt_len,
+                int iteration_count,           int hash_idx,
+                unsigned char *out,            unsigned long *outlen)
+\end{alltt}
+Where ``password'' is the users password.  Since the algorithm allows binary passwords you must also specify the length in ``password\_len''.  
+The ``salt'' is an array of size ``salt\_len''.  It should be random for each user and session.  The ``iteration\_count'' is the delay desired
+on the password.  The ``hash\_idx'' is the index of the hash you wish to use in the descriptor table.   The output of length upto 
+``outlen'' is stored in ``out''.
+
+\begin{alltt}
+/* demo to show how to make session state material from a password */
+#include <tomcrypt.h>
+int main(void)

+    unsigned char password[100], salt[100],

+                  mac_key[16], outbuf[48];
+    int           err, hash_idx;

+\}
+\end{alltt}
+
+\chapter{Miscellaneous}
+\section{Base64 Encoding and Decoding}
+The library provides functions to encode and decode a RFC1521 base64 coding scheme.  This means that it can decode what it 
+encodes but the format used does not comply to any known standard.  The characters used in the mappings are:
+\begin{verbatim}
+ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/
+\end{verbatim}
+Those characters should are supported in virtually any 7-bit ASCII system which means they can be used for transport over
+common e-mail, usenet and HTTP mediums.  The format of an encoded stream is just a literal sequence of ASCII characters
+where a group of four represent 24-bits of input.  The first four chars of the encoders output is the length of the 
+original input.  After the first four characters is the rest of the message.
+
+Often it is desirable to line wrap the output to fit nicely in an e-mail or usenet posting.  The decoder allows you to
+put any character (that is not in the above sequence) in between any character of the encoders output.  You may not however,
+break up the first four characters.
+
+To encode a binary string in base64 call:
+\index{base64\_encode()}  \index{base64\_decode()} 
+\begin{verbatim}
+int base64_encode(const unsigned char *in, unsigned long len, 
+                  unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+Where ``in'' is the binary string and ``out'' is where the ASCII output is placed.  You must set the value of ``outlen'' prior
+to calling this function and it sets the length of the base64 output in ``outlen'' when it is done.  To decode a base64 
+string call:
+\begin{verbatim}
+int base64_decode(const unsigned char *in, unsigned long len, 
+                  unsigned char *out, unsigned long *outlen);
+\end{verbatim}
+
+\section{The Multiple Precision Integer Library (MPI)}
+The library comes with a copy of LibTomMath  which is a multiple precision integer library written by the
+author of LibTomCrypt.  LibTomMath is a trivial to use ANSI C compatible large integer library which is free 
+for all uses and is distributed freely.
+
+At the heart of all the functions is the data type ``mp\_int'' (defined in tommath.h).  This data type is what 
+will hold all large integers.  In order to use an mp\_int one must initialize it first, for example:
+\begin{verbatim}
+#include <tomcrypt.h> /* tomcrypt.h includes mpi.h automatically */
+int main(void)
+{ 
+   mp_int bignum;
+   
+   /* initialize it */
+   mp_init(&bignum);
+
+   return 0;
+}
+\end{verbatim}
+If you are unfamiliar with the syntax of C the \& symbol is used to pass the address of ``bignum'' to the function.  All
+LibTomMath functions require the address of the parameters.  To free the memory of a mp\_int use (for example):
+\begin{verbatim}
+mp_clear(&bignum);
+\end{verbatim}
+
+The functions also have the basic form of one of the following:
+\begin{verbatim}
+mp_XXX(mp_int *a);
+mp_XXX(mp_int *a, mp_int *b, mp_int *c);
+mp_XXX(mp_int *a, mp_int *b, mp_int *c, mp_int *d);
+\end{verbatim}
+
+Where they perform some operation and store the result in the mp\_int variable passed on the far right.  
+For example, to compute $c = a + b \mbox{ }(\mbox{mod }m)$ you would call:
+\begin{verbatim}
+mp_addmod(&a, &b, &m, &c);
+\end{verbatim}
+
+\subsection{Binary Forms of ``mp\_int'' Variables}
+
+Often it is required to store a ``mp\_int'' in binary form for transport (e.g. exporting a key, packet 
+encryption, etc.).  LibTomMath includes two functions to help when exporting numbers:
+\begin{verbatim}
+int mp_raw_size(mp_int *num);
+mp_toraw(&num, buf);
+\end{verbatim}
+
+The former function gives the size in bytes of the raw format and the latter function actually stores the raw data.  All
+``mp\_int'' numbers are stored in big endian form (like PKCS demands) with the first byte being the sign of the number.  The
+``rsa\_exptmod()'' function differs slightly since it will take the input in the form exactly as PKCS demands (without the
+leading sign byte).  All other functions include the sign byte (since its much simpler just to include it).  The sign byte
+must be zero for positive numbers and non-zero for negative numbers.  For example,
+the sequence:
+\begin{verbatim}
+00 FF 30 04
+\end{verbatim}
+Represents the integer $255 \cdot 256^2 + 48 \cdot 256^1 + 4 \cdot 256^0$ or 16,723,972.
+
+To read a binary string back into a ``mp\_int'' call:
+\begin{verbatim}
+mp_read_raw(mp_int *num, unsigned char *str, int len);
+\end{verbatim}
+Where ``num'' is where to store it, ``str'' is the binary string (including the leading sign byte) and ``len'' is the 
+length of the binary string.
+
+\subsection{Primality Testing}
+\index{Primality Testing}
+The library includes primality testing and random prime functions as well.  The primality tester will perform the test in
+two phases.  First it will perform trial division by the first few primes.  Second it will perform eight rounds of the 
+Rabin-Miller primality testing algorithm.  If the candidate passes both phases it is declared prime otherwise it is declared
+composite.  No prime number will fail the two phases but composites can.  Each round of the Rabin-Miller algorithm reduces
+the probability of a pseudo-prime by $1 \over 4$ therefore after sixteen rounds the probability is no more than 
+$\left ( { 1 \over 4 } \right )^{8} = 2^{-16}$.  In practice the probability of error is in fact much lower than that.
+
+When making random primes the trial division step is in fact an optimized implementation of ``Implementation of Fast RSA Key Generation on Smart Cards''\footnote{Chenghuai Lu, Andre L. M. dos Santos and Francisco R. Pimentel}.
+In essence a table of machine-word sized residues are kept of a candidate modulo a set of primes.  When the candiate
+is rejected and ultimately incremented to test the next number the residues are updated without using multi-word precision
+math operations.  As a result the routine can scan ahead to the next number required for testing with very little work
+involved.
+
+In the event that a composite did make it through it would most likely cause the the algorithm trying to use it to fail.  For 
+instance, in RSA two primes $p$ and $q$ are required.  The order of the multiplicative sub-group (modulo $pq$) is given 
+as $\phi(pq)$ or $(p - 1)(q - 1)$.  The decryption exponent $d$ is found as $de \equiv 1\mbox{ }(\mbox{mod } \phi(pq))$.  If either $p$ or $q$ is composite the value of $d$ will be incorrect and the user
+will not be able to sign or decrypt messages at all.  Suppose $p$ was prime and $q$ was composite this is just a variation of 
+the multi-prime RSA.  Suppose $q = rs$ for two primes $r$ and $s$ then $\phi(pq) = (p - 1)(r - 1)(s - 1)$ which clearly is 
+not equal to $(p - 1)(rs - 1)$.
+
+These are not technically part of the LibTomMath library but this is the best place to document them.  
+To test if a ``mp\_int'' is prime call:
+\begin{verbatim}
+int is_prime(mp_int *N, int *result);
+\end{verbatim}
+This puts a one in ``result'' if the number is probably prime, otherwise it places a zero in it.  It is assumed that if 
+it returns an error that the value in ``result'' is undefined.  To make 
+a random prime call:
+\begin{verbatim}
+int rand_prime(mp_int *N, unsigned long len, prng_state *prng, int wprng);
+\end{verbatim}
+Where ``len'' is the size of the prime in bytes ($2 \le len \le 256$).  You can set ``len'' to the negative size you want
+to get a prime of the form $p \equiv 3\mbox{ }(\mbox{mod } 4)$.  So if you want a 1024-bit prime of this sort pass 
+``len = -128'' to the function.  Upon success it will return {\bf CRYPT\_OK} and ``N'' will contain an integer which
+is very likely prime.
+
+\chapter{Programming Guidelines}
+
+\section{Secure Pseudo Random Number Generators}
+Probably the singal most vulnerable point of any cryptosystem is the PRNG.  Without one generating and protecting secrets
+would be impossible.  The requirement that one be setup correctly is vitally important and to address this point the library
+does provide two RNG sources that will address the largest amount of end users as possible.  The ``sprng'' PRNG provided 
+provides and easy to access source of entropy for any application on a *NIX or Windows computer.  
+
+However, when the end user is not on one of these platforms the application developer must address the issue of finding
+entropy.  This manual is not designed to be a text on cryptography.  I would just like to highlight that when you design
+a cryptosystem make sure the first problem you solve is getting a fresh source of entropy.  
+
+\section{Preventing Trivial Errors}
+Two simple ways to prevent trivial errors is to prevent overflows and to check the return values.  All of the functions
+which output variable length strings will require you to pass the length of the destination.  If the size of your output
+buffer is smaller than the output it will report an error.  Therefore, make sure the size you pass is correct!
+
+Also virtually all of the functions return an error code or {\bf CRYPT\_OK}.  You should detect all errors as simple 
+typos or such can cause algorithms to fail to work as desired.
+
+\section{Registering Your Algorithms}
+To avoid linking and other runtime errors it is important to register the ciphers, hashes and PRNGs you intend to use 
+before you try to use them.  This includes any function which would use an algorithm indirectly through a descriptor table.
+
+A neat bonus to the registry system is that you can add external algorithms that are not part of the library without 
+having to hack the library.  For example, suppose you have a hardware specific PRNG on your system.  You could easily 
+write the few functions required plus a descriptor.  After registering your PRNG all of the library functions that 
+need a PRNG can instantly take advantage of it.
+
+\section{Key Sizes}
+
+\subsection{Symmetric Ciphers}
+For symmetric ciphers use as large as of a key as possible.  For the most part ``bits are cheap'' so using a 256-bit key
+is not a hard thing todo.  
+
+\subsection{Assymetric Ciphers}
+The following chart gives the work factor for solving a DH/RSA public key using the NFS.  The work factor for a key of order
+$n$ is estimated to be
+\begin{equation}
+e^{1.923 \cdot ln(n)^{1 \over 3} \cdot ln(ln(n))^{2 \over 3}} 
+\end{equation}
+
+Note that $n$ is not the bit-length but the magnitude.  For example, for a 1024-bit key $n = 2^{1024}$.  The work required 
+is:
+\begin{center}
+\begin{tabular}{|c|c|}
+    \hline RSA/DH Key Size (bits) & Work Factor ($log_2$) \\
+    \hline 512 & 63.92 \\
+    \hline 768 & 76.50 \\
+    \hline 1024 & 86.76 \\
+    \hline 1536 & 103.37 \\
+    \hline 2048 & 116.88 \\
+    \hline 2560 & 128.47 \\
+    \hline 3072 & 138.73 \\
+    \hline 4096 & 156.49 \\
+    \hline 
+\end{tabular}
+\end{center}
+
+The work factor for ECC keys is much higher since the best attack is still fully exponentional.  Given a key of magnitude
+$n$ it requires $\sqrt n$ work.  The following table sumarizes the work required:
+\begin{center}
+\begin{tabular}{|c|c|}
+    \hline ECC Key Size (bits) & Work Factor ($log_2$) \\
+    \hline 192 & 96  \\
+    \hline 224 & 112 \\
+    \hline 256 & 128 \\
+    \hline 384 & 192 \\
+    \hline 521 & 260.5 \\
+    \hline
+\end{tabular}
+\end{center}
+
+Using the above tables the following suggestions for key sizes seems appropriate:
+\begin{center}
+\begin{tabular}{|c|c|c|}
+    \hline Security Goal & RSA/DH Key Size (bits) & ECC Key Size (bits) \\
+    \hline Short term (less than a year) & 1024 & 160 \\
+    \hline Short term (less than five years) & 1536 & 192 \\
+    \hline Long Term (less than ten years) & 2560 & 256 \\
+    \hline 
+\end{tabular}
+\end{center}
+
+\section{Thread Safety}
+The library is not thread safe but several simple precautions can be taken to avoid any problems.  The registry functions
+such as register\_cipher() are not thread safe no matter what you do.  Its best to call them from your programs initializtion
+code before threads are initiated.
+
+The rest of the code uses state variables you must pass it such as hash\_state, hmac\_state, etc.  This means that if each
+thread has its own state variables then they will not affect each other.  This is fairly simple with symmetric ciphers
+and hashes.  However, the keyring and PRNG support is something the threads will want to share.  The simplest workaround 
+is create semaphores or mutexes around calls to those functions.  
+
+Since C does not have standard semaphores this support is not native to Libtomcrypt.  Even a C based semaphore is not entire
+possible as some compilers may ignore the ``volatile'' keyword or have multiple processors.  Provide your host application
+is modular enough putting the locks in the right place should not bloat the code significantly and will solve all thread
+safety issues within the library.
+
+\chapter{Configuring and Building the Library}
+\section{Introduction}
+The library is fairly flexible about how it can be built, used and generally distributed.  Additions are being made with
+each new release that will make the library even more flexible.  Each of the classes of functions can be disabled during
+the build process to make a smaller library.  This is particularly useful for shared libraries.
+
+\section{Building a Static Library}
+The library can be built as a static library which is generally the simplest and most portable method of 
+building the library.  With a CC or GCC equipped platform you can issue the following
+
+\begin{alltt}
+make install_lib
+\end{alltt}
+
+Which will build the library and install it in /usr/lib (as well as the headers in /usr/include).  The destination
+directory of the library and headers can be changed by editing ``makefile''.  The variable LIBNAME controls
+where the library is to be installed and INCNAME controls where the headers are to be installed.  A developer can 
+then use the library by including ``tomcrypt.h'' in their program and linking against ``libtomcrypt.a''.
+
+A static library can also be built with the Intel C Compiler  (ICC) by issuing the following
+
+\begin{alltt}
+make -f makefile.icc install
+\end{alltt}
+
+This will also build ``libtomcrypt.a'' except that it will use ICC.  Additionally Microsoft's Visual C 6.00 can be used
+by issuing
+
+\begin{alltt}
+nmake -f makefile.msvc
+\end{alltt}
+
+You will have to manually copy ``tomcrypt.lib'' and the headers to your MSVC lib/inc directories.
+
+\subsection{MPI Control}
+If you already have LibTomMath installed you can safely remove it from the build.  By commenting the line
+in the appropriate makefile which starts with 
+
+\begin{alltt}
+MPIOBJECT=mpi
+\end{alltt}
+
+Simply place a \# at the start and re-build the library.  To properly link applications you will have to also
+link in LibTomMath.  Removing MPI has the benefit of cutting down the library size as well potentially have access
+to the latest mpi.
+
+\section{Building a Shared Library}
+LibTomCrypt can also be built as a shared library (.so, .dll, etc...).  With non-Windows platforms the assumption
+of the presence of gcc and ``libtool'' has been made.  These are fairly common on Unix/Linux/BSD platforms.  To
+build a .so shared library issue 
+
+\begin{alltt}
+make -f makefile.shared
+\end{alltt}
+This will use libtool and gcc to build a shared library ``libtomcrypt.la'' as well as a static library ``libtomcrypt.a''
+and install them into /usr/lib (and the headers into /usr/include).  To link your application you should use the 
+libtool program in ``--mode=link''.
+
+\section{tomcrypt\_cfg.h}
+The file ``tomcrypt\_cfg.h'' is what lets you control various high level macros which control the behaviour 
+of the library. 
+
+\subsubsection{ARGTYPE}
+This lets you control how the \_ARGCHK macro will behave.  The macro is used to check pointers inside the functions against
+NULL.  There are three settings for ARGTYPE.  When set to 0 it will have the default behaviour of printing a message to 
+stderr and raising a SIGABRT signal.  This is provided so all platforms that use libtomcrypt can have an error that functions
+similarly.  When set to 1 it will simply pass on to the assert() macro.  When set to 2 it will resolve to a empty macro
+and no error checking will be performed.
+
+\subsubsection{Endianess}
+There are five macros related to endianess issues.  For little endian platforms define, ENDIAN\_LITTLE.  For big endian
+platforms define ENDIAN\_BIG.  Similarly when the default word size of an ``unsigned long'' is 32-bits define ENDIAN\_32BITWORD
+or define ENDIAN\_64BITWORD when its 64-bits.  If you do not define any of them the library will automatically use ENDIAN\_NEUTRAL
+which will work on all platforms.
+
+Currently LibTomCrypt will detect x86-32 and x86-64 running GCC as well as x86-32 running MSVC.  
+
+\section{The Configure Script}
+There are also options you can specify from the configure script or ``tomcrypt\_custom.h''.  
+
+\subsection{X memory routines}
+At the top of tomcrypt\_custom.h are four macros denoted as XMALLOC, XCALLOC, XREALLOC and XFREE which resolve to 
+the name of the respective functions.  This lets you substitute in your own memory routines.  If you substitute in 
+your own functions they must behave like the standard C library functions in terms of what they expect as input and 
+output.  By default the library uses the standard C routines.
+
+\subsection{X clock routines}
+The rng\_get\_bytes() function can call a function that requires the clock() function.  These macros let you override
+the default clock() used with a replacement.  By default the standard C library clock() function is used.
+
+\subsection{NO\_FILE}
+During the build if NO\_FILE is defined then any function in the library that uses file I/O will not call the file I/O 
+functions and instead simply return CRYPT\_NOP.  This should help resolve any linker errors stemming from a lack of
+file I/O on embedded platforms.
+
+\subsection{CLEAN\_STACK}
+When this functions is defined the functions that store key material on the stack will clean up afterwards.  
+Assumes that you have no memory paging with the stack.
+
+\subsection{LTC\_TEST}
+When this has been defined the various self--test functions (for ciphers, hashes, prngs, etc) are included in the build.
+When this has been undefined the tests are removed and if called will return CRYPT\_NOP.
+
+\subsection{Symmetric Ciphers, One-way Hashes, PRNGS and Public Key Functions}
+There are a plethora of macros for the ciphers, hashes, PRNGs and public key functions which are fairly 
+self-explanatory.  When they are defined the functionality is included otherwise it is not.  There are some 
+dependency issues which are noted in the file.  For instance, Yarrow requires CTR chaining mode, a block 
+cipher and a hash function.
+
+\subsection{TWOFISH\_SMALL and TWOFISH\_TABLES}
+Twofish is a 128-bit symmetric block cipher that is provided within the library.  The cipher itself is flexible enough
+to allow some tradeoffs in the implementation.  When TWOFISH\_SMALL is defined the scheduled symmetric key for Twofish 
+requires only 200 bytes of memory.  This is achieved by not pre-computing the substitution boxes.  Having this 
+defined will also greatly slow down the cipher.  When this macro is not defined Twofish will pre-compute the 
+tables at a cost of 4KB of memory.  The cipher will be much faster as a result.  
+
+When TWOFISH\_TABLES is defined the cipher will use pre-computed (and fixed in code) tables required to work.  This is
+useful when TWOFISH\_SMALL is defined as the table values are computed on the fly.  When this is defined the code size
+will increase by approximately 500 bytes.  If this is defined but TWOFISH\_SMALL is not the cipher will still work but
+it will not speed up the encryption or decryption functions.
+
+\subsection{GCM\_TABLES}
+When defined GCM will use a 64KB table (per GCM state) which will greatly speed up the per--packet latency.  
+It also increases the initialization time and isn't suitable when you are going to use a key a few times only.  
+
+\subsection{SMALL\_CODE}
+When this is defined some of the code such as the Rijndael and SAFER+ ciphers are replaced with smaller code variants.
+These variants are slower but can save quite a bit of code space.
+
+\subsection{LTC\_FAST}
+This mode (autodetected with x86\_32,x86\_64 platforms with GCC or MSVC) configures various routines such as ctr\_encrypt() or 
+cbc\_encrypt() that it can safely XOR multiple octets in one step by using a larger data type.  This has the benefit of 
+cutting down the overhead of the respective functions.  
+
+This mode does have one downside.  It can cause unaligned reads from memory if you are not careful with the functions.  This is why
+it has been enabled by default only for the x86 class of processors where unaligned accesses are allowed.  Technically LTC\_FAST
+is not ``portable'' since unaligned accesses are not covered by the ISO C specifications.
+
+In practice however, you can use it on pretty much any platform (even MIPS) with care.
+
+By design the ``fast'' mode functions won't get unaligned on their own.  For instance, if you call ctr\_encrypt() right after calling
+ctr\_start() and all the inputs you gave are aligned than ctr\_encrypt() will perform aligned memory operations only.  However, if you 
+call ctr\_encrypt() with an odd amount of plaintext then call it again the CTR pad (the IV) will be partially used.  This will
+cause the ctr routine to first use up the remaining pad bytes.  Then if there are enough plaintext bytes left it will use 
+whole word XOR operations.  These operations will be unaligned.
+
+The simplest precaution is to make sure you process all data in power of two blocks and handle ``remainder'' at the end.  e.g. If you are 
+CTR'ing a long stream process it in blocks of (say) four kilobytes and handle any remaining incomplete blocks at the end of the stream.  
+
+If you do plan on using the ``LTC\_FAST'' mode you have to also define a ``LTC\_FAST\_TYPE'' macro which resolves to an optimal sized
+data type you can perform integer operations with.  Ideally it should be four or eight bytes since it must properly divide the size 
+of your block cipher (e.g. 16 bytes for AES).  This means sadly if you're on a platform with 57--bit words (or something) you can't 
+use this mode.  So sad.
+
+\subsection{LTC\_PTHREAD}
+When this is activated all of the descriptor table functions will use pthread locking to ensure thread safe updates to the tables.  Note that 
+it doesn't prevent a thread that is passively using a table from being messed up by another thread that updates the table.
+
+Generally the rule of thumb is to setup the tables once at startup and then leave them be.  This added build flag simply makes updating
+the tables safer.
+
+\section{MPI Tweaks}
+\subsection{RSA Only Tweak}
+If you plan on only using RSA with moduli in the range of 1024 to 2560 bits you can enable a series of tweaks
+to reduce the library size.  Follow these steps
+
+\begin{enumerate}
+   \item Undefine MDSA, MECC and MDH from tomcrypt\_custom.h
+   \item Undefine LTM\_ALL  from tommath\_superclass.h
+   \item Define SC\_RSA\_1 from tommath\_superclass.h
+   \item Rebuild the library.
+\end{enumerate}
+
+\chapter{Optimizations}
+\section{Introduction}
+The entire API was designed with plug and play in mind at the low level.  That is you can swap out any cipher, hash or PRNG and dependent API will not require
+updating.  This has the nice benefit that I can add ciphers not have to re--write large portions of the API.  For the most part LibTomCrypt has also been written
+to be highly portable and easy to build out of the box on pretty much any platform.  As such there are no assembler inlines throughout the code, I make no assumptions
+about the platform, etc...
+
+That works well for most cases but there are times where time is of the essence.  This API also allows optimized routines to be dropped in--place of the existing
+portable routines.  For instance, hand optimized assembler versions of AES could be provided and any existing function that uses the cipher could automatically use
+the optimized code without re--writing.  This also paves the way for hardware drivers that can access hardware accelerated cryptographic devices.
+
+At the heart of this flexibility is the ``descriptor'' system.  A descriptor is essentially just a C ``struct'' which describes the algorithm and provides pointers
+to functions that do the work.  For a given class of operation (e.g. cipher, hash, prng) the functions have identical prototypes which makes development simple.  In most
+dependent routines all a developer has to do is register\_XXX() the descriptor and they're set.
+
+\section{Ciphers}
+The ciphers in LibTomCrypt are accessed through the ltc\_cipher\_descriptor structure.
+
+\begin{small}
+\begin{verbatim}
+struct ltc_cipher_descriptor {
+   /** name of cipher */

+
+\subsection{Name}
+The ``name'' parameter specifies the name of the cipher.  This is what a developer would pass to find\_cipher() to find the cipher in the descriptor
+tables.
+
+\subsection{Internal ID}
+This is a single byte Internal ID you can use to distingish ciphers from each other.
+
+\subsection{Key Lengths}
+The minimum key length is ``min\_key\_length'' and is measured in octets.  Similarly the maximum key length is ``max\_key\_length''.  They can be equal
+and both must valid key sizes for the cipher.  Values in between are not assumed to be valid though they may be.
+
+\subsection{Block Length}
+The size of the ciphers plaintext or ciphertext is ``block\_length'' and is measured in octets.
+
+\subsection{Rounds}
+Some ciphers allow different number of rounds to be used.  Usually you just use the default.  The default round count is ``default\_rounds''.
+
+\subsection{Setup}
+To initialize a cipher (for ECB mode) the function setup() was provided.  It accepts an array of key octets ``key'' of length ``keylen'' octets.  The user
+can specify the number of rounds they want through ``num\_rounds'' where $num\_rounds = 0$ means use the default.  The destination of a scheduled key is stored
+in ``skey''.
+
+Inside the ``symmetric\_key'' union there is a ``void *data'' which you can use to allocate data if you need a data structure that doesn't fit with the existing
+ones provided.  Just make sure in your ``done()'' function that you free the allocated memory.
+
+\subsection{Single block ECB}
+To process a single block in ECB mode the ecb\_encrypt() and ecb\_decrypt() functions were provided.  The plaintext and ciphertext buffers are allowed to overlap so you 
+must make sure you do not overwrite the output before you are finished with the input.
+
+\subsection{Testing}
+The test() function is used to self--test the ``device''.  It takes no arguments and returns \textbf{CRYPT\_OK} if all is working properly.
+
+\subsection{Key Sizing}
+Occasionally a function will want to find a suitable key size to use since the input is oddly sized.  The keysize() function is for this case.  It accepts a 
+pointer to an integer which represents the desired size.  The function then has to match it to the exact or a lower key size that is valid for the cipher.  For
+example, if the input is $25$ and $24$ is valid then it stores $24$ back in the pointed to integer.  It must not round up and must return an error if the keysize
+ cannot be mapped to a valid key size for the cipher.
+
+\subsection{Acceleration}
+The next set of functions cover the accelerated functionality of the cipher descriptor.  Any combination of these functions may be set to \textbf{NULL} to indicate
+it is not supported.  In those cases the software fallbacks are used (using the single ECB block routines).
+
+\subsubsection{Accelerated ECB}
+These two functions are meant for cases where a user wants to encrypt (in ECB mode no less) an array of blocks.  These functions are accessed
+through the accel\_ecb\_encrypt and accel\_ecb\_decrypt pointers.  The ``blocks'' count is the number of complete blocks to process.
+
+\subsubsection{Accelerated CBC} 
+These two functions are meant for accelerated CBC encryption.  These functions are accessed through the accel\_cbc\_encrypt and accel\_cbc\_decrypt pointers.
+The ``blocks'' value is the number of complete blocks to process.  The ``IV'' is the CBC initial vector.  It is an input upon calling this function and must be
+updated by the function before returning.  
+
+\subsubsection{Accelerated CTR}
+This function is meant for accelerated CTR encryption.  It is accessible through the accel\_ctr\_encrypt pointer.
+The ``blocks'' value is the number of complete blocks to process.  The ``IV'' is the CTR counter vector.  It is an input upon calling this function and must be
+updated by the function before returning.  The ``mode'' value indicates whether the counter is big (mode = CTR\_COUNTER\_BIG\_ENDIAN) or 
+little (mode = CTR\_COUNTER\_LITTLE\_ENDIAN) endian.
+
+This function (and the way it's called) differs from the other two since ctr\_encrypt() allows any size input plaintext.  The accelerator will only be
+called if the following conditions are met.
+
+\begin{enumerate}
+   \item The accelerator is present
+   \item The CTR pad is empty
+   \item The remaining length of the input to process is greater than or equal to the block size.
+\end{enumerate}
+
+The ``CTR pad'' is empty when a multiple (including zero) blocks of text have been processed.  That is, if you pass in seven bytes to AES--CTR mode you would have to 
+pass in a minimum of nine extra bytes before the accelerator could be called.  The CTR accelerator must increment the counter (and store it back into the 
+buffer provided) before encrypting it to create the pad.  
+
+The accelerator will only be used to encrypt whole blocks.  Partial blocks are always handled in software.
+
+\subsubsection{Accelerated CCM}
+This function is meant for accelerated CCM encryption or decryption.  It processes the entire packet in one call.  Note that the setup() function will not
+be called prior to this.  This function must handle scheduling the key provided on its own.
+
+\subsubsection{Accelerated GCM}
+This function is meant for accelerated GCM encryption or decryption.  It processes the entire packet in one call.  Note that the setup() function will not
+be called prior to this.  This function must handle scheduling the key provided on its own.
+
+\section{One--Way Hashes}
+The hash functions are accessed through the ltc\_hash\_descriptor structure.
+
+\begin{small}
+\begin{verbatim}
+struct ltc_hash_descriptor {
+    /** name of hash */
+    char *name;
+    /** internal ID */
+    unsigned char ID;
+    /** Size of digest in octets */
+    unsigned long hashsize;
+    /** Input block size in octets */
+    unsigned long blocksize;
+    /** ASN.1 OID */
+    unsigned long OID[16];
+    /** Length of DER encoding */
+    unsigned long OIDlen;
+    /** Init a hash state
+      @param hash   The hash to initialize
+      @return CRYPT_OK if successful

+    int (*init)(hash_state *hash);
+    /** Process a block of data 
+      @param hash   The hash state
+      @param in     The data to hash
+      @param inlen  The length of the data (octets)
+      @return CRYPT_OK if successful
+    */
+    int (*process)(hash_state *hash, const unsigned char *in, unsigned long inlen);
+    /** Produce the digest and store it
+      @param hash   The hash state
+      @param out    [out] The destination of the digest
+      @return CRYPT_OK if successful
+    */
+    int (*done)(hash_state *hash, unsigned char *out);
+    /** Self-test
+      @return CRYPT_OK if successful, CRYPT_NOP if self-tests have been disabled
+    */
+    int (*test)(void);
+};
+\end{verbatim}
+\end{small}
+
+\subsection{Name}
+This is the name the hash is known by and what find\_hash() will look for.
+
+\subsection{Internal ID}
+This is the internal ID byte used to distinguish the hash from other hashes.
+
+\subsection{Digest Size}
+The ``hashsize'' variable indicates the length of the output in octets.
+
+\subsection{Block Size}
+The `blocksize'' variable indicates the length of input (in octets) that the hash processes in a given
+invokation.
+
+\subsection{OID Identifier}
+This is the universal ASN.1 Object Identifier for the hash.
+
+\subsection{Initialization}
+The init function initializes the hash and prepares it to process message bytes.
+
+\subsection{Process}
+This processes message bytes.  The algorithm must accept any length of input that the hash would allow.  The input is not
+guaranteed to be a multiple of the block size in length.
+
+\subsection{Done}
+The done function terminates the hash and returns the message digest.
+
+\subsection{Acceleration}
+A compatible accelerator must allow processing data in any granularity which may require internal padding on the driver side.  
+
+\section{Pseudo--Random Number Generators}
+The pseudo--random number generators are accessible through the ltc\_prng\_descriptor structure.
+
+\begin{small}
+\begin{verbatim}
+struct ltc_prng_descriptor {
+    /** Name of the PRNG */
+    char *name;

+        @return CRYPT_OK if successful
+    */
+    int (*add_entropy)(const unsigned char *in, unsigned long inlen, prng_state *prng);
+    /** Ready a PRNG state to read from
+        @param prng       The PRNG state to ready

+    /** Read from the PRNG

+        @param outlen  Length of data desired (octets)
+        @param prng    The PRNG state to read from
+        @return Number of octets read
+    */
+    unsigned long (*read)(unsigned char *out, unsigned long outlen, prng_state *prng);
+    /** Terminate a PRNG state
+        @param prng   The PRNG state to terminate
+        @return CRYPT_OK if successful
+    */
+    int (*done)(prng_state *prng);
+    /** Export a PRNG state  
+        @param out     [out] The destination for the state
+        @param outlen  [in/out] The max size and resulting size of the PRNG state
+        @param prng    The PRNG to export

+    int (*pexport)(unsigned char *out, unsigned long *outlen, prng_state *prng);
+    /** Import a PRNG state
+        @param in      The data to import
+        @param inlen   The length of the data to import (octets)
+        @param prng    The PRNG to initialize/import
+        @return CRYPT_OK if successful
+    */
+    int (*pimport)(const unsigned char *in, unsigned long inlen, prng_state *prng);
+    /** Self-test the PRNG
+        @return CRYPT_OK if successful, CRYPT_NOP if self-testing has been disabled
+    */
+    int (*test)(void);
+};
+\end{verbatim}
+\end{small}
+
+\subsection{Name}
+The name by which find\_prng() will find the PRNG.
+
+\subsection{Export Size}
+When an PRNG state is to be exported for future use you specify the space required in this variable.
+
+\subsection{Start}
+Initialize the PRNG and make it ready to accept entropy.
+
+\subsection{Entropy Addition}
+Add entropy to the PRNG state.  The exact behaviour of this function depends on the particulars of the PRNG.
+
+\subsection{Ready}
+This function makes the PRNG ready to read from by processing the entropy added.  The behaviour of this function depends
+on the specific PRNG used.
+
+\subsection{Read}
+Read from the PRNG and return the number of bytes read.  This function does not have to fill the buffer but it is best 
+if it does as many protocols do not retry reads and will fail on the first try.
+
+\subsection{Done}
+Terminate a PRNG state.  The behaviour of this function depends on the particular PRNG used.
+
+\subsection{Exporting and Importing}
+An exported PRNG state is data that the PRNG can later import to resume activity.  They're not meant to resume ``the same session''
+but should at least maintain the same level of state entropy.

+# MAKEFILE for linux ICC (Intel C compiler)
+#
+# Tested with ICC v8....
+#
+# Be aware that ICC isn't quite as stable as GCC and several optimization switches
+# seem to break the code (that GCC and MSVC compile just fine).  In particular
+# "-ip" and "-x*" seem to break the code (ROL/ROR macro problems).  As the makefile 
+# is shipped the code will build and execute properly.
+#
+# Also note that ICC often makes code that is slower than GCC.  This is probably due to 
+# a mix of not being able to use "-ip" and just having fewer optimization algos than GCC.

+Tech Note 0001
+How to Gather Entropy on Embedded Systems
+Tom St Denis
+
+Introduction
+------------
+
+This tech note explains a relatively simple way to gather entropy for a PRNG (Yarrow in this case) in embedded systems
+where there are few sources of entropy or physical sources.
+
+When trying to setup a secure random number generator a fresh source of random data (entropy) is required to ensure the
+deterministic state of the PRNG is not known or predetermined with respect to an attacker.
+
+At the very least the system requires one timer and one source of un-timed interrupts.  by "un-timed" I mean interrupts
+that do not occur at regular intervals [e.g. joypad/keypad input, network packets, etc...].
+
+First we shall begin by taking an overview of how the Yarrow PRNG works within libtomcrypt.  At the heart of all
+PRNGs is the "prng_state" data type.  This is a union of structures that hold the PRNG state for the various prngs.  The 
+first thing we require is a state... 
+
+   prng_state myPrng;
+
+Next we must initialize the state once to get the ball rolling
+
+   if (yarrow_start(&myPrng) != CRYPT_OK) {
+      // error should never happen!
+   }
+
+At this point the PRNG is ready to accept fresh entropy which is added with
+
+   int yarrow_add_entropy(const unsigned char *buf, unsigned long len, prng_state *prng)
+
+This function is **NOT** thread safe which will come under consideration later.  To add entropy to our PRNG we must 
+call this function with fresh data as its sampled.  Lets say we have a timer counter called "uTimer" which is a 32-bit 
+long and say a 32-bit joyPad state called "uPad".  An example interrupt handler would look like
+
+   void joypad_interrupt(...) {
+       unsigned char buf[8];
+
+       STORE32L(uTimer, buf);
+       STORE32L(uPad, buf+4)
+       if (yarrow_add_entropy(buf, 8, &myPrng) != CRYPT_OK) {
+          // this should never occur either unless you didn't call yarrow_start
+       }
+ 
+       // handle interrupt
+   }
+
+In this snippet the timer count and state of the joypad are added together into the entropy pool.  The timer is important
+because with respect to the joypad it is a good source of entropy (on its own its not).  For example, the probability of
+the user pushing the up arrow is fairly high, but at a specific time is not.
+
+This method doesn't gather alot of entropy and has to be used to for quite a while.  One way to speed it up is to tap
+multiple sources.  If you have a network adapter and other sources of events (keyboard, mouse, etc...) trapping their
+data is ideal as well.  Its important to gather the timer along with the event data.
+
+As mentioned the "yarrow_add_entropy()" function is not thread safe.  If your system allows interrupt handlers to be 
+interrupted themselves then you could have trouble.  One simple way is to detect when an interrupt is in progress and
+simply not add entropy during the call (jump over the yarrow_add_entropy() call)
+
+Once you feel that there has been enough entropy added to the pool then within a single thread you can call
+
+    int yarrow_ready(prng_state *prng)
+
+Now the PRNG is ready to read via the 
+
+    unsigned long yarrow_read(unsigned char *buf, unsigned long len, prng_state *prng)
+
+It is a very good idea that once you call the yarrow_ready() function that you stop harvesting entropy in your interrupt
+functions.  This will free up alot of CPU time.  Also one more final note.  The yarrow_read() function is not thread
+safe either.  This means if you have multiple threads or processes that read from it you will have to add your own semaphores
+around calls to it.

+Tech Note 0002
+How to avoid non-intrusive timing attacks with online computations
+Tom St Denis
+
+Introduction
+------------
+
+A timing attack is when an attacker can observe a side channel of the device (in this case time).  In this tech note
+we consider only non-intrusive timing attacks with respect to online computations.  That is an attacker can
+determine when a computation (such as a public key encryption) begins and ends but cannot observe the device 
+directly.  This is specifically important for applications which transmit data via a public network.
+
+Consider a Diffie-Hellman encryption which requires the sender to make up a public key "y = g^x mod p".  Libtomcrypt
+uses the MPI bignum library to perform the operation.  The time it takes to compute y is controlled by the number
+of 1 bits in the exponent 'x'.  To a large extent there will be the same number of squaring operations.  "1" bits in
+the exponent require the sender to perform a multiplication.  This means to a certain extent an attacker can 
+determine not only the magnitude of 'x' but the number of one bits.  With this information the attacker cannot directly
+learn the key used.  However, good cryptography mandates the close scrutiny of any practical side channel.
+
+Similar logic applies to the other various routines.  Fortunately for this case there is a simple solution.  First, 
+determine the maximum time the particular operation can require.  For instance, on an Athlon 1.53Ghz XP processor a
+DH-768 encryption requires roughly 50 milliseconds.  Take that time and round it up.  Now place a delay after the call.
+
+For example, 
+
+void demo(void) {
+   clock_t t1;
+
+   // get initial clock
+   t1 = clock();
+   
+   // some PK function
+   
+   // now delay 
+   while (clock() < (t1 + 100));
+   
+   // transmit data...
+   
+}
+
+This code has the effect of taking at least 100 ms always.  In effect someone analyzing the traffic will see that the
+operations always take a fixed amount of time.  Since no two platforms are the same this type of fix has not been 
+incorporated into libtomcrypt (nor is it desired for many platforms).  This requires on the developers part to profile
+the code to determine the delays required.
+
+Note that this "quick" fix has no effect against an intrusive attacker.  For example, power consumption will drop
+significantly in the loop after the operation.  However, this type of fix is more important to secure the user of the 
+application/device.  For example, a user placing an order online won't try to cheat themselves by cracking open their
+device and performing side-channel cryptanalysis.  An attacker over a network might try to use the timing information
+against the user.

+Minimizing Memory Usage
+Tom St Denis
+
+Introduction
+------------
+
+For the most part the library can get by with around 20KB of stack and about 32KB of heap even if you use the
+public key functions.  If all you plan on using are the hashes and ciphers than only about 1KB of stack is required
+and no heap.
+
+To save space all of the symmetric key scheduled keys are stored in a union called "symmetric_key".  This means the 
+size of a symmetric_key is the size of the largest scheduled key.  By removing the ciphers you don't use from
+the build you can minimize the size of this structure.  For instance, by removing both Twofish and Blowfish the
+size reduces to 768 bytes from the 4,256 bytes it would have been (on a 32-bit platform).  Or if you remove
+Blowfish and use Twofish with TWOFISH_SMALL defined its still 768 bytes.  Even at its largest the structure is only 
+4KB which is normally not a problem for any platform.  
+

+fairly fast as well.

+Tech Note 0004
+Using Yarrow, Fortuna and SOBER-128
+Tom St Denis
+
+Introduction
+------------
+
+This tech note explains how to use three of the more useful pseudo random number generators and their 
+own little "issues".  While all of the PRNGs have the same API and are roughly used in the same 
+manner their effectiveness really depends on the user knowing how they work.
+
+
+Yarrow
+------
+
+Yarrow is by far the simplest of the PRNGs.  It gathers bits of entropy by hashing the pool state
+plus the additional bits storing the message digest back in the pool.  E.g.
+
+pool = hash(pool || newbits)
+
+Simply dump bits into the PRNG via yarrow_add_entropy() and call yarrow_ready() when you want to 
+put them to use.  This PRNG while simple is not entirely safe.  An attacker who learns the state
+of the pool and can control future events can control the PRNG.  This requires an active attacker but 
+isn't entire impossible.
+
+The pool is then used as a key for a cipher that is used in CTR mode.  
+
+Yarrow is mostly meant for short-term programs [e.g. like file utils].  This particular implementation
+is not meant for long-term usage.
+
+Fortuna
+-------
+
+Fortuna was designed by Niels Fergusson and Bruce Schneier [Bruce is also the guy who invented Yarrow].  It
+operates on a more defensive level than Yarrow.  Instead of 1 entropy pool it has 32 and the new entropy 
+is spread [round robin] in all of the pools. 
+
+That is, each call to fortuna_add_entropy() puts the bits in the next [in the sequenece] pool of entropy.  
+Effective bits are added to the pool by sending them through a hash [but not terminating the hash].  
+
+Here's the main catch though.  When the PRNG must be reseeded [so that you can extract bits from it] only
+certain pools are used.  More precisely the i'th pool is used every 2**i'th reseeding.  For example, pool[0]
+is always used.  pool[1] is used every second reseeding, pool[2] every fourth.
+
+The pools are hashed together along with the current key and the result is the new key for a cipher which
+operates in CTR mode [more about that in a sec].
+
+Now this may seem odd at first however there is a good reason behind it.  An attacker who learns pool[0] won't
+strictly know the other pools.  So the recovery rate of is not 0.  In fact pool[0] can be completely 
+compromised and the PRNG will still eventually recover.  The value FORTUNA_WD is the "WatchDog" counter.
+Every FORTUNA_WD calls to fortuna_read will invoke the reseed operation.  By default this is set to 10 which 
+means after 10 calls the PRNG will reseed itself.  
+
+The pools are combined with the running cipher key [256 bits] so that a cipher in CTR mode can produce 
+the stream.  Unlike Yarrow the cipher is re-keyed after every call to fortuna_read() [so one big call 
+would be faster than many smaller calls].  This prevents too much data being encrypted under the same
+key [and mitigates a flaw in CTR mode that the same block can't be emitted twice under the same key].
+
+Fortuna is really meant for a kernel-level PRNG.  The more sources [and often] you feed into it the 
+healthier it will be.  It's also meant to be used for long term purposes.  Since it can recover from
+compromises it is harder to control it.  
+
+SOBER-128
+------
+
+SOBER-128 is actually a stream cipher but like most ciphers can easily be modelled in the context of a PRNG.
+This PRNG is extremely fast [4 cycles/byte on a P4] and was designed by a well known cryptographer [Greg Rose].
+
+SOBER-128 doesn't really "act" like the other two PRNGs.  It's meant to be seeded once and then read as 
+required.  In such a sense it isn't a "system PRNG" but useful short term purposes.  In particular
+the sober128_read() function actually XORs against the input buffer you specify.  This allows the 
+read() function to be used as an "encrypt" function as well.  
+
+You can only key SOBER-128 once [by calling sober128_add_entropy()].  Once it it is keyed subsequent
+calls to add_entropy() will be considered a "re-IV" operation.  Changing the IV allows you to use same
+initial key and not produce the same output stream.  It also lets you differentiate packets.  E.g. each
+packet has it's own IV.
+
+All inputs to sober128_add_entropy() must have a length that is a multiple of four.
+
+Overall
+-------
+
+Since SOBER-128 is *much* faster than the other two PRNGs a good setup would be to use Fortuna as your 
+system-wide PRNG and use SOBER-128 [key'ed from Fortuna] for encrypting streams or as a PRNG for 
+simulations.
+
+Yarrow is still a good candidate but only for "short lived" programs.  However, since Fortuna is faster
+[by about 10 cycles/byte on a P4] I'd use Fortuna anyways...

+/**********************************************************************\
+* To commemorate the 1996 RSA Data Security Conference, the following  *
+* code is released into the public domain by its author.  Prost!       *
+*                                                                      *
+* This cipher uses 16-bit words and little-endian byte ordering.       *
+* I wonder which processor it was optimized for?                       *
+*                                                                      *
