All Implemented Interfaces:

JabberMessageParsable

public class PGPSignedXMessage
extends JabberJDOMMessage

Support PGP signed messages. This class will work with PGP-signed message. It's really simple because it simply contains only the encrypted data. It will not do any encryption for you. That is up to you to implement on the client level since developers use different Encryption packages to encrypt data.

Signed messages are normally used for messages. The signing should use Status string of the Presence message, and signed using the private key of the sender.

There are actually three types of PGP-signed messages and this only handles two types: detached and clearsign. If you have a copy of Gnupg you can create a detached PGP message with the command gpg -ab filename. A detched PGP message begins with a '-----BEGIN PGP SIGNATURE-----' header and ends with '-----END PGP SIGNATURE-----'. Using Gnupg you can create a clearsign PGP message with the command gpg -clearsign filename. Clearsign messages contain the same headers as a detached message but the also contain a leading '-----BEGIN PGP SIGNED MESSAGE-----' and a plaintext copy of the data that has been signed.
