[Cryptix-users] PGP Desktop Armoured signed message issues

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi.  I'm trying to use the cryptix library to verify a message sent
against a public key.  I've managed to do this successfully for
plaintext emails sent and signed using both OpenPGP and PGPDesktop. 
However html emails sent using PGPDesktop appear to do things a little
differently to other html email signing apps.
It produces the Signature as a detached signature and doesn't appear to
have a BEGIN PGP MESSAGE block.  Could anyone tell me which parts of the
following message are included in the signature and how I should go
about verifying these parts against the signature.  At the moment I
generateMessages using a message factory then cast as a SignedMessage
then verify against the public key.  but the
MessageFactory.generateMessages doesn't appear to work for these emails.

The email I wish to very follows:

Content-Type: multipart/signed;
boundary="PGP_Universal_6B953E55_15A796E5_56A705A0_EBCD36FC";
protocol="application/pgp-signature";
micalg="pgp-sha1"

--PGP_Universal_6B953E55_15A796E5_56A705A0_EBCD36FC
Content-Type: multipart/alternative;
boundary="----=_NextPart_000_000D_01C6FBFE.5F722960"

This is a multi-part message in MIME format.
