The OpenSSH client requests a maximum packet size of 16384, but this MIN_PACKET_SIZE value of 32768 causes its request to be "clamped" up to 32768, later causing an error to stderr on the OpenSSH client. Suggest then, to delineate MIN_WINDOW_SIZE from MIN_PACKET_SIZE, as they are applied.

Previously only 256-bit was handled and in certain cases (private key reading) 384- and 521-bit keys were treated as 256-bit keys causing silent errors. Tests have been added to specifically test the 384 and 521 keysizes. As RFC 5656 defines 256, 384, and 521 as the required keysizes this seems a good set to test. Also, this will cover the branches at ecdsakey.py:55. Test keys were renamed and test_client.py was modified as a result. This also fixes two bugs in ecdsakey.py. First, when calculating bytes needed to store a key, the assumption was made that the key size (in bits) was divisible by 8 (see line 137). This has been fixed by rounding up (wasn't an issue as only 256-bit keys were used before). Another bug was that the key padding in asbytes was being done backwards (was padding on current_length - needed_length bytes). --- paramiko/ecdsakey.py | 117 +++++++++++++++++++---- paramiko/hostkeys.py | 2 +- paramiko/transport.py | 3 +- tests/test_client.py | 6 +- tests/test_ecdsa.key | 5 - tests/test_ecdsa_256.key | 5 + tests/test_ecdsa_384.key | 6 ++ tests/test_ecdsa_521.key | 7 ++ tests/test_ecdsa_password.key | 8 -- tests/test_ecdsa_password_256.key | 8 ++ tests/test_ecdsa_password_384.key | 9 ++ tests/test_ecdsa_password_521.key | 10 ++ tests/test_pkey.py | 190 ++++++++++++++++++++++++++++++++++---- 13 files changed, 321 insertions(+), 55 deletions(-) delete mode 100644 tests/test_ecdsa.key create mode 100644 tests/test_ecdsa_256.key create mode 100644 tests/test_ecdsa_384.key create mode 100644 tests/test_ecdsa_521.key delete mode 100644 tests/test_ecdsa_password.key create mode 100644 tests/test_ecdsa_password_256.key create mode 100644 tests/test_ecdsa_password_384.key create mode 100644 tests/test_ecdsa_password_521.key (limited to 'tests') diff --git a/paramiko/ecdsakey.py b/paramiko/ecdsakey.py index c69bef73..6663baa2 100644 --- a/paramiko/ecdsakey.py +++ b/paramiko/ecdsakey.py @@ -37,12 +37,71 @@ from paramiko.ssh_exception import SSHException from paramiko.util import deflate_long, inflate_long +class _ECDSACurve(object): + """ + Object for representing a specific ECDSA Curve (i.e. nistp256, nistp384, + etc.).
