Credit to + ``@timsavage``. +* :support:`921` Tighten up the ``__hash__`` implementation for various key + classes; less code is good code. Thanks to Francisco Couzo for the patch. +* :bug:`983` Move ``sha1`` above the now-arguably-broken ``md5`` in the list of + preferred MAC algorithms, as an incremental security improvement for users + whose target systems offer both. Credit: Pierce Lopez. +* :bug:`667` The RC4/arcfour family of ciphers has been broken since version + 2.0; but since the algorithm is now known to be completely insecure, we are + opting to remove support outright instead of fixing it. Thanks to Alex Gaynor + for catch & patch. +* :feature:`857` Allow `SSHClient.set_missing_host_key_policy + <paramiko.client.SSHClient.set_missing_host_key_policy>` to accept policy + classes _or_ instances, instead of only instances, thus fixing a + long-standing gotcha for unaware users. +* :feature:`951` Add support for ECDH key exchange (kex), specifically the + algorithms ``ecdh-sha2-nistp256``, ``ecdh-sha2-nistp384``, and + ``ecdh-sha2-nistp521``. They now come before the older ``diffie-hellman-*`` + family of kex algorithms in the preferred-kex list.

This improves compatibility with + OpenSSH, both in terms of general behavior, and also re: ability to properly + leverage OpenSSH-modified ``known_hosts`` files. Credit: ``@kasdoe`` for + original report/PR and Pierce Lopez for the second draft. +* :bug:`794` (via :issue:`981`) Prior support for ``ecdsa-sha2-nistp(384|521)`` + algorithms didn't fully extend to covering host keys, preventing connection + to hosts which only offer these key types and no others.

Big thanks to Alex Gaynor for the patch. + + .. note:: + This change adds the ``bcrypt`` and ``pynacl`` Python libraries as + dependencies. No C-level dependencies beyond those previously required (for + Cryptography) have been added. + +* :support:`974 backported` Overhaul the codebase to be PEP-8, etc, compliant + (i.e. passes the maintainer's preferred `flake8 <http://flake8.pycqa.org/>`_ + configuration) and add a ``flake8`` step to the Travis config.

Thanks to Sofian Brabez. +* :bug:`44 (1.17+)` (via :issue:`891`) `SSHClient <paramiko.client.SSHClient>` + now gives its internal `Transport <paramiko.transport.Transport>` a handle on + itself, preventing garbage collection of the client until the session is + closed.

Credit to Jason R. Coombs. +* :bug:`824 (1.17+)` Fix the implementation of ``PKey.write_private_key_file`` + (this method is only publicly defined on subclasses; the fix was in the + private real implementation) so it passes the correct params to ``open()``. + This bug apparently went unnoticed and unfixed for 12 entire years.

This helps prevent situations where + network connectivity isn't timing out, but the remote server is otherwise + unable to service the connection in a timely manner. Credit to + ``@sanseihappa``. +* :bug:`742` (also re: :issue:`559`) Catch ``AssertionError`` thrown by + Cryptography when attempting to load bad ECDSA keys, turning it into an + ``SSHException``. This moves the behavior in line with other "bad keys" + situations, re: Paramiko's main auth loop. Thanks to MengHuan Yu for the + patch. +* :bug:`789 (1.17+)` Add a missing ``.closed`` attribute (plus ``._closed`` + because reasons) to `ProxyCommand <paramiko.proxy.ProxyCommand>` so the + earlier partial fix for :issue:`520` works in situations where one is + gatewaying via ``ProxyCommand``. +* :bug:`334 (1.17+)` Make the ``subprocess`` import in ``proxy.py`` lazy so + users on platforms without it (such as Google App Engine) can import Paramiko + successfully. (Relatedly, make it easier to tweak an active socket check + timeout [in `Transport <paramiko.transport.Transport>`] which was previously + hardcoded.) Credit: Shinya Okano. +* :support:`854 backported (1.17+)` Fix incorrect docstring/param-list for + `Transport.auth_gssapi_keyex + <paramiko.transport.Transport.auth_gssapi_keyex>` so it matches the real + signature. Caught by ``@Score_Under``. +* :bug:`681 (1.17+)` Fix a Python3-specific bug re: the handling of read + buffers when using ``ProxyCommand``. Thanks to Paul Kapp for catch & patch. +* :feature:`398 (1.18+)` Add an ``environment`` dict argument to + `Client.exec_command <paramiko.client.SSHClient.exec_command>` (plus the + lower level `Channel.update_environment + <paramiko.channel.Channel.update_environment>` and + `Channel.set_environment_variable + <paramiko.channel.Channel.set_environment_variable>` methods) which + implements the ``env`` SSH message type. This means the remote shell + environment can be set without the use of ``VARNAME=value`` shell tricks, + provided the server's ``AcceptEnv`` lists the variables you need to set. + Thanks to Philip Lorenz for the pull request. +* :support:`819 backported (>=1.15,<2.0)` Document how lacking ``gmp`` headers + at install time can cause a significant performance hit if you build PyCrypto + from source.

Thanks to ``@Depado`` for the initial report and + Paul Kapp for the fix. +* :bug:`774 (1.16+)` Add a ``_closed`` private attribute to + `~paramiko.channel.Channel` objects so that they continue functioning when + used as proxy sockets under Python 3 (e.g. as ``direct-tcpip`` gateways for + other Paramiko connections.) +* :bug:`758 (1.16+)` Apply type definitions to ``_winapi`` module from + `jaraco.windows <https://github.com/jaraco/jaraco.windows>`_ 3.6.1. This + should address issues on Windows platforms that often result in errors like + ``ArgumentError: [...] int too long to convert``. Thanks to ``@swohlerLL`` + for the report and Jason R. Coombs for the patch. +* :release:`2.0.1 <2016-06-21>` +* :release:`1.17.1 <2016-06-21>` +* :release:`1.16.2 <2016-06-21>` +* :bug:`520 (1.16+)` (Partial fix) Fix at least one instance of race condition + driven threading hangs at end of the Python interpreter session. (Includes a + docs update as well - always make sure to ``.close()`` your clients!) +* :bug:`537 (1.16+)` Fix a bug in `BufferedPipe.set_event + <paramiko.buffered_pipe.BufferedPipe.set_event>` which could cause + deadlocks/hangs when one uses `select.select` against + `~paramiko.channel.Channel` objects (or otherwise calls `Channel.fileno + <paramiko.channel.Channel.fileno>` after the channel has closed). Thanks to + Przemysław Strzelczak for the report & reproduction case, and to Krzysztof + Rusek for the fix. +* :release:`2.0.0 <2016-04-28>` +* :release:`1.17.0 <2016-04-28>` +* :release:`1.16.1 <2016-04-28>` +* :release:`1.15.5 <2016-04-28>` +* :feature:`731` (working off the earlier :issue:`611`) Add support for 384- + and 512-bit elliptic curve groups in ECDSA key types (aka + ``ecdsa-sha2-nistp384`` / ``ecdsa-sha2-nistp521``). Thanks to Michiel Tiller + and ``@CrazyCasta`` for the patches. +* :bug:`670` Due to an earlier bugfix, less-specific ``Host`` blocks' + ``ProxyCommand`` values were overriding ``ProxyCommand none`` in + more-specific ``Host`` blocks. This has been fixed in a backwards compatible + manner (i.e. ``ProxyCommand none`` continues to appear as a total lack of any + ``proxycommand`` key in parsed config structures). Thanks to Pat Brisbin for + the catch. +* :bug:`676` (via :issue:`677`) Fix a backwards incompatibility issue that + cropped up in `SFTPFile.prefetch <paramiko.sftp_file.SFTPFile.prefetch>` re: + the erroneously non-optional ``file_size`` parameter. Should only affect + users who manually call ``prefetch``. Thanks to ``@stevevanhooser`` for catch + & patch. +* :feature:`394` Replace PyCrypto with the Python Cryptographic Authority + (PyCA) 'Cryptography' library suite. This improves security, installability, + and performance; adds PyPy support; and much more. + + There aren't enough ways to thank Alex Gaynor for all of his work on this, + and then his patience while the maintainer let his PR grow moss for a year + and change. Paul Kehrer came in with an assist, and I think I saw Olle + Lundberg, ``@techtonik`` and ``@johnthagen`` supplying backup as well. Thanks + to all! + + .. warning:: + **This is a backwards incompatible change.** + + However, **it should only affect installation** requirements; **no API + changes are intended or expected**. Please report any such breakages as + bugs. + + See our updated :doc:`installation docs <installing>` for details on what + is now required to install Paramiko; many/most users should be able to + simply ``pip install -U paramiko`` (especially if you **upgrade to pip + 8**). + +* :bug:`577` (via :issue:`578`; should also fix :issue:`718`, :issue:`560`) Fix + stalled/hung SFTP downloads by cleaning up some threading lock issues. Thanks + to Stephen C. Pope for the patch. +* :bug:`716` Fix a Python 3 compatibility issue when handling two-factor + authentication. Thanks to Mateusz Kowalski for the catch & original patch. +* :support:`729 backported (>=1.15,<2.0)` Clean up ``setup.py`` to always use + ``setuptools``, not doing so was a historical artifact from bygone days. + Thanks to Alex Gaynor. +* :bug:`649 major (==1.17)` Update the module in charge of handling SSH moduli + so it's consistent with OpenSSH behavior re: prime number selection. Thanks + to Damien Tournoud for catch & patch. +* :bug:`617` (aka `fabric/fabric#1429 + <https://github.com/fabric/fabric/issues/1429>`_; via :issue:`679`; related: + :issue:`678`, :issue:`685`, :issue:`615` & :issue:`616`) Fix up + `~paramiko.ssh_exception.NoValidConnectionsError` so it pickles correctly, + and fix a related Python 3 compatibility issue. Thanks to Rebecca Schlussel + for the report & Marius Gedminas for the patch. +* :bug:`613` (via :issue:`619`) Update to ``jaraco.windows`` 3.4.1 to fix some + errors related to ``ctypes`` on Windows platforms. Credit to Jason R. Coombs. +* :support:`621 backported (>=1.15,<2.0)` Annotate some public attributes on + `~paramiko.channel.Channel` such as ``.closed``. Thanks to Sergey Vasilyev + for the report. +* :bug:`632` Fix logic bug in the SFTP client's callback-calling functionality; + previously there was a chance the given callback would fire twice at the end + of a transfer. Thanks to ``@ab9-er`` for catch & original patch. +* :support:`612 backported (>=1.15,<2.0)` Identify & work around a race + condition in the test for handshake timeouts, which was causing frequent test + failures for a subset of contributors as well as Travis-CI (usually, but not + always, limited to Python 3.5). Props to Ed Kellett for assistance during + some of the troubleshooting. +* :support:`697 backported (>=1.15,<2.0)` Remove whitespace in our + ``setup.py``'s ``install_requires`` as it triggers occasional bugs in some + versions of ``setuptools``. Thanks to Justin Lecher for catch & original + patch. +* :bug:`499` Strip trailing/leading whitespace from lines when parsing SSH + config files - this brings things in line with OpenSSH behavior. Thanks to + Alfredo Esteban for the original report and Nick Pillitteri for the patch. +* :bug:`652` Fix behavior of ``gssapi-with-mic`` auth requests so they fail + gracefully (allowing followup via other auth methods) instead of raising an + exception. Patch courtesy of ``@jamercee``. +* :feature:`588 (==1.17)` Add missing file-like object methods for + `~paramiko.file.BufferedFile` and `~paramiko.sftp_file.SFTPFile`. Thanks to + Adam Meily for the patch. +* :support:`636 backported (>=1.15,<2.0)` Clean up and enhance the README (and + rename it to ``README.rst`` from just ``README``). Thanks to ``@LucasRMehl``. +* :release:`1.16.0 <2015-11-04>` +* :bug:`194 major` (also :issue:`562`, :issue:`530`, :issue:`576`) Streamline + use of ``stat`` when downloading SFTP files via `SFTPClient.get + <paramiko.sftp_client.SFTPClient.get>`; this avoids triggering bugs in some + off-spec SFTP servers such as IBM Sterling. Thanks to ``@muraleee`` for the + initial report and to Torkil Gustavsen for the patch. +* :feature:`467` (also :issue:`139`, :issue:`412`) Fully enable two-factor + authentication (e.g. when a server requires ``AuthenticationMethods + pubkey,keyboard-interactive``). Thanks to ``@perryjrandall`` for the patch + and to ``@nevins-b`` and Matt Robenolt for additional support. +* :bug:`502 major` Fix 'exec' requests in server mode to use ``get_string`` + instead of ``get_text`` to avoid ``UnicodeDecodeError`` on non-UTF-8 input. + Thanks to Anselm Kruis for the patch & discussion. +* :bug:`401` Fix line number reporting in log output regarding invalid + ``known_hosts`` line entries.

Thanks to Alex Gaynor. +* :support:`594 backported` Correct some post-Python3-port docstrings to + specify ``bytes`` type instead of ``str``. Credit to ``@redixin``. +* :bug:`565` Don't explode with ``IndexError`` when reading private key files + lacking an ``-----END <type> PRIVATE KEY-----`` footer. Patch courtesy of + Prasanna Santhanam. +* :feature:`604` Add support for the ``aes192-ctr`` and ``aes192-cbc`` ciphers. + Thanks to Michiel Tiller for noticing it was as easy as tweaking some key + sizes :D +* :feature:`356` (also :issue:`596`, :issue:`365`, :issue:`341`, :issue:`164`, + :issue:`581`, and a bunch of other duplicates besides) Add support for SHA-2 + based key exchange (kex) algorithm ``diffie-hellman-group-exchange-sha256`` + and (H)MAC algorithms ``hmac-sha2-256`` and ``hmac-sha2-512``. + + This change includes tweaks to debug-level logging regarding + algorithm-selection handshakes; the old all-in-one log line is now multiple + easier-to-read, printed-at-handshake-time log lines. + + Thanks to the many people who submitted patches for this functionality and/or + assisted in testing those patches.
