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::X509::Extension::subjectAltName - X.509 subjectAltName extension

SYNOPSIS

my $san = Crypt::Perl::X509::Extension::subjectAltName->new(
    [ dNSName => 'foo.com' ],
    [ dNSName => 'bar.com' ],
    [ rfc822Name => 'haha@tld.com' ],
);

DESCRIPTION

Instances of this class represent a subjectAltName extension of an X.509 (SSL) certificate.

You probably don’t need to instantiate this class directly; instead, you can instantiate it implicitly by listing out arguments to Crypt::Perl::PKCS10’s constructor. See that module’s SYNOPSIS for an example.

You can also use instances of this class as arguments to Crypt::Perl::PKCS10::Attribute::extensionRequest’s constructor to include a request for a subjectAltName extension in a PKCS #10 Certificate Signing Request.
