    00018    RFC 1321 "MD5 Message-Digest Algorithm" Copyright (C) 1991-1992.
    00019    RSA Data Security, Inc. Created 1991. All rights reserved.
    00020
    00021    The KMD5 class is based on a C++ implementation of
    00022    "RSA Data Security, Inc. MD5 Message-Digest Algorithm" by
    00023    Mordechai T. Abzug,  Copyright (c) 1995.  This implementation
    00024    passes the test-suite as defined in RFC 1321.
    00025
    00026    The encoding and decoding utilities in KCodecs with the exception of
    00027    quoted-printable are based on the java implementation in HTTPClient
    00028    package by Ronald Tschalär Copyright (C) 1996-1999.
    00029
    00030    The quoted-printable codec as described in RFC 2045, section 6.7. is by
    00031    Rik Hemsley (C) 2001.
