                      8: **     Contains a generic interface to the message digest algorithms, 
                      9: **      inspired from the RSA-Euro toolkit. For the moment, it only
                     10: **      covers MD5.
                     11: **      SHA and other algorithms could be added later on. This code
                     12: **      is only  used during message digest authentication.
