Crypt::Perl::ECDSA in the Crypt::Perl (aka p5-Crypt-Perl) module prior to 0.32 for Perl fails to verify correct ECDSA signatures when r and s are small and when s = 1. This happens when using the curve secp256r1 (prime256v1). This could conceivably have a security-relevant impact if an attacker wishes to use public r and s values when guessing whether signature verification will fail.

NAME Crypt::Perl - Cryptography in pure Perl DESCRIPTION Just as it sounds: cryptography with no non-core XS dependencies! This is useful if you don’t have access to other tools that do this work like OpenSSL, CryptX, etc Of course, if you do have access to one of those tools, they may suit your purpose better See submodules for usage examples of: Key generation
