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;
	   Sets first member of signature pair.

       $s = $sig_obj->set_s;
