        !             8: **     Contains a generic interface to the message digest algorithms, 
        !             9: **      inspired from the RSA-Euro toolkit. For the moment, it only

        !            11: **      SHA and other algorithms could be added later on. This code
        !            12: **      is only  used during message digest authentication.
