NAME
Crypt::Perl::X509::Extension::keyUsage
SYNOPSIS
my $usage_obj = Crypt::Perl::X509::Extension::subjectKeyIdentifier->new(
$subj_key_id #octet string
);ECDSA/EC/Point.pm in Crypt::Perl before 0.33 does not properly consider timing attacks against the EC point multiplication algorithm.
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.

my $usage_obj = Crypt::Perl::X509::Extension::subjectKeyIdentifier->new(
$subj_key_id #octet string
