The Crypt::DSA (aka Crypt-DSA) module 1.17 and earlier for Perl, when /dev/random is absent, uses the Data::Random module, which makes it easier for remote attackers to spoof a signature, or determine the signing key of a signed message, via a brute-force attack.
Crypt::DSA::Signature - DSA signature object
use Crypt::DSA::Signature;
my $sig = Crypt::DSA::Signature->new;
$sig->r($r);
$sig->s($s);Please see the Crypt::DSA manpage for author, copyright, and license information.
To install Crypt::DSA, copy and paste the appropriate command in to your terminal.
cpanm Crypt::DSAperl -MCPAN -e shell
install Crypt::DSAFor more information on module installation, please visit the detailed CPAN module installation guide.
