CAVEAT
THIS MODULE IS OFFICIALLY UNSUPPORTED.
Please move on to DKIM like a responsible Internet user. I have.
I will leave this module here on CPAN for a while, just in case someone
has grown to depend on it. It is apparent that DK will not be the way
of the future. Thus, it is time to put this module to ground before it
causes any further harm.
Thanks for your support, Anthony
SYNOPSISMail::DomainKeys is a perl implementation of Yahoo's mail signature
protocol.
This library allows one to sign and verify signatures as per draft 03
of the DomainKeys specification:
http://www.ietf.org/internet-drafts/draft-delany-domainkeys-base-03.txt
A Simple Example
This example shows the simplest possible DomainKeys signature verifier.
require Mail::DomainKeys::Message;
# load a message from a filehandle glob
my $mail = load Mail::DomainKeys::Message(File => \*STDIN) or
die "unable to load message\n";
# check to make sure the sender has a fully qualified domain
$mail->senderdomain or
die "unable to verify message: no sender domain\n";
# check if the mail is signed by DomainKeys
$mail->signed or
die "no signature\n";
# check the signature
if ($mail->verify) {
print STDERR "signature valid\n";
exit 0;
}
# the signature was not valid
die "unable to verify signature\n";
This example shows the simplest possible DomainKeys signer.
require Mail::DomainKeys::Message;
require Mail::DomainKeys::Key::Private;
# load the message, or die trying
my $mail = load Mail::DomainKeys::Message(File => \*STDIN) or
die "unable to load message";
# load the private key, or die trying
my $priv = load Mail::DomainKeys::Key::Private(File => "private.key") or
die "unable to load key";
# sign the message using the "simple" canonifier and selector "test"
$mail->sign(Method => "simple", Selector => "test", Private => $priv);
# print out the signature
print $mail->signature->as_string;
