NAME
       Mail::DKIM::Algorithm::Base - base class for DKIM "algorithms"
SYNOPSIS
         my $algorithm = new Mail::DKIM::Algorithm::rsa_sha1(
                             Signature => $dkim_signature
                         );
         # add headers
         $algorithm->add_header("Subject: this is the subject\015\012");
         $algorithm->finish_header;
         # add body
         $algorithm->add_body("This is the body.\015\012");
         $algorithm->add_body("Another line of the body.\015\012");
         $algorithm->finish_body;
         # now sign or verify...
         # TODO...
CONSTRUCTOR
       You should not create an object of this class directly. Instead, use
       one of the DKIM algorithm implementation classes, such as rsa_sha1:
         my $algorithm = new Mail::DKIM::Algorithm::rsa_sha1(
                             Signature => $dkim_signature
                         );
METHODS
   add_body() - feeds part of the body into the algorithm/canonicalization
         $algorithm->add_body("This is the body.\015\012");
         $algorithm->add_body("Another line of the body.\015\012");
       The body should be fed one "line" at a time.
   add_header() - feeds a header field into the algorithm/canonicalization
         $algorithm->add_header("Subject: this is the subject\015\012");
       The header must start with the header field name and continue through
       any folded lines (including the embedded <CRLF> sequences). It
       terminates with the <CRLF> at the end of the header field.
   finish_body() - signals the end of the message body
         $algorithm->finish_body
       Call this method when all lines from the body have been submitted.
       After calling this method, use sign() or verify() to get the results
       from the algorithm.
   finish_header() - signals the end of the header field block
         $algorithm->finish_header;
       Call this method when all the headers have been submitted.
   sign() - generates a signature using a private key
         $base64 = $algorithm->sign($private_key);
   signature() - get/set the signature worked on by this algorithm
         my $old_signature = $algorithm->signature;
         $algorithm->signature($new_signature);
   verify() - verifies a signature
         $result = $algorithm->verify();
       Must be called after finish_body().
       The result is a true/false value: true indicates the signature data is
       valid, false indicates it is invalid.
       For an invalid signature, details may be obtained from
       $algorithm->{verification_details} or $@.
