public class PGPSignService
extends ServiceImp

This service provides a way to sign messages via GPG/PGP. It requires a private key, the passphrase to unlock the key, and a message to sign. Optionally it will ASCII armor encode the signature (default) and create a detached signature (default).

    </pgp-sign>
 

In the adapter configuration file this class is aliased as pgp-sign which is the preferred alternative to the fully qualified classname when building your configuration.

a stream that will return PGP binary encoded data.

Throws:
