25  Independent implementation of MD5 (RFC 1321).
26
27  This code implements the MD5 Algorithm defined in RFC 1321.
28  It is derived directly from the text of the RFC and not from the
29  reference implementation.

36  1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
37        added conditionalization for C++ compilation from Martin
38        Purschke <purschke@bnl.gov>.
