NAME

       Mail::DKIM::Canonicalization::Base - base class for canonicalization methods

SYNOPSIS

	 # canonicalization results get output to STDOUT
	 my $method = new Mail::DKIM::Canonicalization::relaxed(
			   output_fh => *STDOUT,
			   Signature => $dkim_signature);

	 # add headers
	 $method->add_header("Subject: this is the subject1512");
	 $method->finish_header;

	 # add body
	 $method->add_body("This is the body.1512");
	 $method->add_body("Another two lines1512of the body.1512");
	 $method->finish_body;

	 # this adds the signature to the end
	 $method->finish_message;

CONSTRUCTOR

       Use the new() method of the desired canonicalization implementation class to construct a canonicalization object. E.g.

	 my $method = new Mail::DKIM::Canonicalization::relaxed(
			   output_fh => *STDOUT,
			   Signature => $dkim_signature);

       The constructors accept these arguments:

       Signature
	   (Required) Provide the DKIM signature being constructed (if the message is being signed), or the DKIM signature being verified (if the
	   message is being verified). The canonicalization method either writes parameters to the signature, or reads parameters from the
	   signature (e.g. the h= tag).

       output
	   If specified, the canonicalized message will be passed to this object with the PRINT method.

       output_digest
	   If specified, the canonicalized message will be added to this digest.  (Uses the add() method.)

       output_fh
	   If specified, the canonicalized message will be written to this file handle.

       If none of the output parameters are specified, then the canonicalized message is appended to an internal buffer. The contents of this
       buffer can be accessed using the result() method.

METHODS

   add_body() - feeds part of the body into the canonicalization
	 $method->add_body("This is the body.1512");
	 $method->add_body("Another two lines1512of the body.1512");

       The body should be fed one or more "lines" at a time.  I.e. do not feed part of a line.

   result()
	 my $result = $method->result;

       If you did not specify an object or handle to send the output to, the result of the canonicalization is stored in the canonicalization
       method itself, and can be accessed using this method.
