# Crypt::DSA::Signature(3pm)

DSA signature object

## 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.
