NAME

Crypt::DSA::Signature - DSA signature object

SYNOPSIS

    use Crypt::DSA::Signature;
    my $sig = Crypt::DSA::Signature->new;

    $sig->r($r);
    $sig->s($s);

DESCRIPTION

Crypt::DSA::Signature represents a DSA signature. It has 2 methods, r and s, which are the big number representations of the 2 pieces of the DSA signature.

USAGE

Crypt::DSA::Signature->new( %options )

Creates a new signature object, and optionally initializes it with the information in %options, which can contain:

  • Content

    An ASN.1-encoded string representing the DSA signature. In ASN.1 notation, this looks like:

        SEQUENCE {
            r INTEGER,
            s INTEGER
        }

    If Content is provided, new will automatically call the deserialize method to parse the content, and set the r and s methods on the resulting Crypt::DSA::Signature object.

$sig->serialize

Serializes the signature object $sig into the format described above: an ASN.1-encoded representation of the signature, using the ASN.1 syntax above.
