mail::dkim::canonicalization::base
Mail::DKIM::Canonicalization::Base(3) User Contributed Perl Documentation Mail::DKIM::Canonicalization::Base(3)
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 subject 15 12");
$method->finish_header(Headers => @all_headers);
# add body
$method->add_body("This is the body. 15 12");
$method->add_body("Another two lines 15 12of the body. 15 12");
$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. 15 12");
$method->add_body("Another two lines 15 12of the body. 15 12");
The body should be fed one or more "lines" at a time. I.e. do not feed part of a line.
finish_header() - called when the header has been completely parsed
$method->finish_header(Headers => @all_headers);
Formerly the canonicalization object would only get the header data through successive invocations of add_header(). However, that required
the canonicalization object to store a copy of the entire header so that it could choose the order in which headers were fed to the digest
object. This is inefficient use of memory, since a message with many signatures may use many canonicalization objects and each
canonicalization object has its own copy of the header.
The headers array is an array of one element per header field, with the headers not processed/canonicalized in any way.
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.
