// Revision 1.1.1.1  2002/08/27 12:32:13  grosbois
// Add cryptix 3.2
//
// Revision 1.2  1997/12/08 10:02:07  raif
// *** empty log message ***
//
// 1997.12.08 --RSN
// + modified the semantics of the AlgId bytes.
// + documentation changes.
//
// Revision 1.1  1997/11/23 02:24:59  hopwood
// + Changed the naming convention for signature classes.
//   "PKCS1" is used instead of "PEM", because PKCS#1 is a signature
//   (and encryption) formatting standard, whereas PEM is a complete secure
//   mail standard.
//
// Revision 1.1.1.1  1997/11/03 22:36:56  hopwood
// + Imported to CVS (tagged as 'start').
//
// Revision 0.1.0.1  1997/07/30  David Hopwood
// + Renamed this class to RIPEMD160_RSA_PEMSignature (from
//   RSA_RIPEMD160Signature).
// + Renamed getAlgorithmId to getAlgorithmEncoding.
//
// Revision 0.1.0.0  1997/07/28  R. Naffah
