* Future proofing use of the six python version constants (#4238)Eric Brown2018-05-143-27/+27
| | | | | | | | | | | | | | | * Future proofing use of the six python version constants After reading [1], noticed that cryptography uses a lot of if six.PY3 blocks. The issue with this is that whenever Python 4 is released, this code in the else block will be executed even though it was only intended for Python 2. [1] http://astrofrog.github.io/blog/2016/01/12/stop-writing-python-4-incompatible-code/ Signed-off-by: Eric Brown <browne@vmware.com> * Use not PY2 instead
* Remove some unused RSA bindings. (#4243)David Benjamin2018-05-141-11/+0
| | | | | | RSA_blinding_off is a silly function. RSA_SSLV23_PADDING and RSA_X931_PADDING are obsolete. The low-level padding functions appear unused and the EVP_PKEY stuff is probably a bit nicer than expecting callers to RSA_NO_PADDING and do the padding by hand.
* Validate the public/private halves of EC keys on import. (#4241)David Benjamin2018-05-142-6/+7
| | | | | | | | | | | | | | | | | | * Validate the public/private halves of EC keys on import. OpenSSL's API is a little finicky. If one sets the public key before the private key, it does not validate that they match. If set in the other order, it does validate this. In particular, KASValidityTest_ECCStaticUnified_NOKC_ZZOnly_init.fax describes error code 7 as: Result = F (7 - IUT's Static private key d changed-prikey validity) Reordering the two operations makes those tests to fail on key import, which is what CAVP appears to have intended. * Wrap to 79 rather than 80 columns
* Fix some stuttering. (#4240)David Benjamin2018-05-141-3/+0
| | | | This is a remnant of the function code checking when this logic looked at both encrypt/decrypt versions of this error code.
* Remove some unused RAND bindings. (#4239)David Benjamin2018-05-141-4/+0
| | | These are unused. (And not especially useful.)
* Clean up unused EC bindings. (#4225)David Benjamin2018-05-142-83/+0
| | | | | | | | | | | | | | | | | | | | | | | * Clean up unused EC bindings. A lot of these are really OpenSSL internals, like the EC_METHOD business, support for custom curves which are a bad idea, and weird non-standard serializations like taking the usual point serialization and treating it as a single BIGNUM. I also didn't remove things when they're arguably part of a set. E.g. EC_POINT_add is used, but EC_POINT_dbl isn't. However, they both set at the same abstraction level (basic point operations), so it's strange to have one without the other. I also kept EC_POINT_is_on_curve because, although it is not used, OpenSSL prior to 1.1.0 doesn't perform this important check in EC_POINT_set_affine_coordinates_GFp (though it does in some of the functions which ultimately call it, like EC_KEY_set_public_key_affine_coordinates, what cryptography.io actually uses), so one should not expose the latter without the former. * Fix build issue.
* Remove unused BIO bindings. (#4220)David Benjamin2018-05-141-107/+3
| | | | | | | | | | | | | * Remove unused BIO bindings. This also folds in the const bits from 1.1.0, on the assumption that, now that the function pointer check is gone, it will just cause cffi to generate more conservative pointer types that work for 1.0.2 as well. * Restore some functions used externally. Datagram BIO_CTRL_* constants are intentionally omitted per discussion on the PR.
* Add SHA512/224 and SHA512/256 test vectors from NIST CAVP (#4237)Paul Kehrer2018-05-149-1/+7121

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add API for retrieving the seconds-to-expiry for the token, given a TTL. * Process PR feedback: * Do compute the TTL, but just the age of the token. The caller can decided what to do next. * Factored out the HMAC signature verification to a separate function. * Fixed a copy&paste mistake in the test cases * Tests cleanup. * `struct` no longer needed * Document `def age()` * typo in `age()` documentation * token, not data * remove test for TTL expiry that is already covered by the parameterized `test_invalid()`. * let's call this extract_timestamp and just return timestamp * review comments * it's UNIX I know this
