| | | | | rsa, and keywrap (#4310) * Refs #3331 -- added initial wycheproof integration, starting with x25519 tests
* Change the exception we raise in keywrap unwrapping on invalid length (#4337)Alex Gaynor2018-07-161-3/+5
| | | I believe this can reasonably be considered backwards compatible since other invalid inputs already lead to InvalidUnwrap, and clients shouldn't be distinguishing between these two conditions, and ValueError wasn't documented anyways.

| | | | | | | | | * raise valueerror for null x25519 derived keys OpenSSL errors when it hits this edge case and a null shared key is bad anyway so let's raise an error * empty commit
* we don't actually care about the errstack here, it's an invalid signature ↵Paul Kehrer2018-07-101-0/+35
| | | | | | | | | | | | | | (#4325) * we don't actually care about the errstack here, it's an invalid signature We previously had no cases where we could error without getting errors on the error stack, but wycheproof contains test cases that can error without adding anything to the stack. Accordingly, we should clear the stack but raise InvalidSignature no matter what (rather than InternalError if we have no error msgs) * add a test

* fix encoding BMPString in x509 name entries (#4321)Paul Kehrer2018-07-091-0/+18
| | | | | | | | | | Previously we encoded them as UTF-8, but as best I can tell in reality a BMPString is fixed-width basic multilingual plane big endian encoding. This is basically UCS-2 (aka original Unicode). However, Python doesn't support UCS-2 encoding so we need to use utf_16_be. This means you can encode surrogate code points that are invalid in the context of what a BMPString is supposed to be, but in reality I strongly suspect the sane encoding ship has sailed and dozens if not hundreds of implementations both do this and expect other systems to handle their nonsense.

* Future proofing use of the six python version constants (#4238)Eric Brown2018-05-142-25/+25
| | | | | | | | | | | | | | | * 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
* Validate the public/private halves of EC keys on import. (#4241)David Benjamin2018-05-141-3/+3
| | | | | | | | | | | | | | | | | | * 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
* Add support for extracting timestamp from a Fernet token (#4229)Paul Kehrer2018-05-121-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
* Raise ve on bad gt (#4180)Joshua Crowgey2018-04-031-0/+12

* Fix ASN1 string type encoding for several Name OIDs (#4035)Paul Kehrer2017-11-301-16/+135
| | | | | | | | | | | | | | | | | | | * Fix ASN1 string type encoding for several Name OIDs When we changed over to the new type encoding system we didn't verify that the new code exactly matched the ASN1 string types that OpenSSL was previously choosing. This caused serialNumber, dnQualifier, emailAddress, and domainComponent to change from their proper encodings to UTF8String as of version 2.1. Now we check to see if there's a sentinel value (indicating no custom type has been passed) and then check if the OID has a different default than UTF8. If it does, we set it. This PR also adds tests for the ASN1 string type of ever supported NameOID. * review feedback
