Security Advisories (2)
CVE-2020-17478 (2020-08-10)

ECDSA/EC/Point.pm in Crypt::Perl before 0.33 does not properly consider timing attacks against the EC point multiplication algorithm.

CVE-2020-13895 (2020-06-07)

Crypt::Perl::ECDSA in the Crypt::Perl (aka p5-Crypt-Perl) module before 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::RSA::Generate - RSA key generation

SYNOPSIS

use Crypt::Perl::RSA::Generate ();

#$prkey is a C::P::R::PrivateKey instance.
my $prkey = Crypt::Perl::RSA::Generate::create(2048);

DISCUSSION

Unfortunately, this is quite slow in Perl. It’s faster if you have the optional XS backends for Math::BigInt and/or Bytes::Random::Secure::Tiny, but it’ll still be orders of magnitude slower than OpenSSL.

If you want it to be faster, have a look at Math::ProvablePrime, and see if you can make any improvements there!
