| | | | | | * create & use _evp_md_from_algorithm and _evp_md_non_null_from_algorithm * remove unused import
* we don't actually care about the errstack here, it's an invalid signature ↵Paul Kehrer2018-07-101-2/+1
| | | | | | | | | | | | | | (#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
* Convert a pair of asserts to use openssl_assert (#4318)Alex Gaynor2018-07-091-2/+2
| | | We have an existence proof that the latter assertion can be triggered, and I bet the former can too.

* Add convenience methods to sign and verify w/ RSA (#2945)Colleen Murphy2016-06-041-0/+11
| | | | | | | | | This patch adds wrapper methods to allow the user to sign and verify a single message block without having to go through the multi-step process of creating a signer or verifier, updating it with the one message, and finalizing the result. This will make signing and verifying data more user-friendly when only using small messages. Partial bug #1529

|
* Add support for RSA_R_OAEP_DECODING_ERROR error flag.Christopher Grebs2015-12-271-0/+3

|
* Move signature type checksStanisław Pitucha2015-08-141-3/+3
| | | | Move the point of checking signatures, as suggested by alex in PR 2262.
* Ensure early exeption on non-bytes signatureStanisław Pitucha2015-08-111-0/+3
| | | | | Signature must be in bytes. If the check is skipped, verify() can explode later in cffi call in _verify_pkey_ctx() for example.
* Remove elifs and replace with else + assertPaul Kehrer2015-08-011-2/+3
| | | | This is kind of ugly, but resolves many partial branch coverage issues.
