Description
The EVP API layer was not rejecting signatures that contained trailing garbage after the
DSA_SIGASN.1 encoding (note it correctly reject invalid signatures regardless). This did not match the behavior of theDSA_verifyandDSA_check_signatureAPIs which explicitly check and reject trailing garbage. This aligns the EVP layer with this behavior.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license and the ISC license.
