Crypt::OpenSSL::DSA::Signature(3)          User Contributed Perl Documentation


NAME
         Crypt::OpenSSL::DSA::Signature - Digital Signature Object

SYNOPSIS
         use Crypt::OpenSSL::DSA;
         my $dsa_priv = Crypt::OpenSSL::DSA->read_priv_key( $filename );
         my $sig_obj = $dsa_priv->do_sign($message);
         my $dsa_pub = Crypt::OpenSSL::DSA->read_pub_key( $filename );
         my $valid = $dsa_pub->do_verify($message, $sig_obj);
         my $sig_size = $dsa_priv->get_sig_size();

         my $r = $sig_obj->get_r;
         my $s = $sig_obj->get_s;

         my $sig_obj2 = Crypt::OpenSSL::DSA::Signature->new();
         $sig_obj2->set_r($r);
         $sig_obj2->set_s($s);
         my $valid = $dsa_pub->do_verify($message, $sig_obj2);

CLASS METHODS
       $sig_obj = Crypt::OpenSSL::DSA::Signature->new();
           Create a new DSA Signature Object.  You will need to call set_r and
           set_s after you create this.

OBJECT METHODS
       $r = $sig_obj->get_r;
           Gets first member of signature pair.

       $s = $sig_obj->get_s;
           Gets second member of signature pair.

       $r = $sig_obj->set_r;
           Sets first member of signature pair.

       $s = $sig_obj->set_s;
           Sets second member of signature pair.
