NAME
       Mail::DKIM::DkSignature - represents a DomainKeys-Signature header
CONSTRUCTORS
   new()
       Create a new DomainKey signature from parameters
         my $signature = Mail::DKIM::DkSignature->new(
                             [ Algorithm => "rsa-sha1", ]
                             [ Signature => $base64, ]
                             [ Method => "simple", ]
                             [ Domain => "example.org", ]
                             [ Headers => "from:subject:date:message-id", ]
                             [ Query => "dns", ]
                             [ Selector => "alpha", ]
                             [ Key => $private_key, ]
                         );
   parse()
       Create a new signature from a DomainKey-Signature header
         my $sig = Mail::DKIM::DkSignature->parse(
                         "DomainKey-Signature: a=rsa-sha1; b=yluiJ7+0=; c=nofws"
                   );
       Constructs a signature by parsing the provided DomainKey-Signature
       header content. You do not have to include the header name (i.e.
       "DomainKey-Signature:") but it is recommended, so the header name can
       be preserved and returned the same way in "as_string()".
       Note: The input to this constructor is in the same format as the output
       of the as_string method.
METHODS
   as_string()
       Convert the signature header as a string.
         print $signature->as_string . "\n";
       outputs
         DomainKey-Signature: a=rsa-sha1; b=yluiJ7+0=; c=nofws
       As shown in the example, the as_string method can be used to generate
       the DomainKey-Signature that gets prepended to a signed message.
   algorithm()
       Get or set the algorithm (a=) field
       The algorithm used to generate the signature.  Defaults to "rsa-sha1",
       an RSA-signed SHA-1 digest.
   canonicalization()
       Get or set the canonicalization (c=) field.
         $signature->canonicalization("nofws");
         $signature->canonicalization("simple");
         $method = $signature->canonicalization;
       Message canonicalization (default is "simple"). This informs the
       verifier of the type of canonicalization used to prepare the message
       for signing.
   domain()
       Get or set the domain (d=) field.
         my $d = $signature->domain;          # gets the domain value
         $signature->domain("example.org");   # sets the domain value
       The domain of the signing entity, as specified in the signature.  This
       is the domain that will be queried for the public key.
   headerlist()
       Get or set the signed header fields (h=) field.
         $signature->headerlist("a:b:c");
         my $headerlist = $signature->headerlist;
         my @headers = $signature->headerlist;
       Signed header fields. A colon-separated list of header field names that
       identify the header fields presented to the signing algorithm.
       In scalar context, the list of header field names will be returned as a
       single string, with the names joined together with colons.  In list
       context, the header field names will be returned as a list.
   identity()
       Get the signing identity.
         my $i = $signature->identity;
       In DomainKey signatures, the signing identity is the first address
       found in the Sender header or the From header. This field is populated
       by the Verifier when processing a DomainKey signature.
   identity_source()
       Determine which header had the identity.
         my $source = $signature->identity_source;
       If the message is being verified, this method will tell you which of
       the message headers was used to determine the signature identity.
       Possible values are "header.sender" and "header.from".
   protocol()
       Get or set the query methods (q=) field.
       A colon-separated list of query methods used to retrieve the public key
       (default is "dns").
   selector()
       Get or set the selector (s=) field.
       The selector subdivides the namespace for the "d=" (domain) tag.
   signature()
       Get or set the signature data (b=) field.
       The signature data. Whitespace is automatically stripped from the
       returned value.
