Crypt::DSA::GMP::Signature(3)

NAME
Crypt::DSA::GMP::Signature - DSA signature object

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

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

DESCRIPTION
Crypt::DSA::GMP::Signature represents a DSA signature. It has two methods, "r" and "s", which are the Math::BigInt representations of the two pieces of the DSA signature.

USAGE

  Crypt::DSA::GMP::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::GMP::Signature object.

METHODS

  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.

  deserialize
Deserializes the ASN.1-encoded representation into a signature object.

  r
One half of the DSA signature for a message. This is a Math::BigInt object.

  s
One half of the DSA signature for a message. This is a Math::BigInt object.
