        Now reports it contains a Mixmaster key.

        Message format changed. Now a key in the encrypted header is
        used to decrypt all the other headers and the body.
        The encrypted header contains a different IV for each header
        and the body.

2.0b5   Fixed the problem with key fingerprints on 
        different architectures.
