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 $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;
