38  Independent implementation of MD5 (RFC 1321).
39 
40  This code implements the MD5 Algorithm defined in RFC 1321, whose
41  text is available at
42  http://www.ietf.org/rfc/rfc1321.txt
43  The code is derived from the text of the RFC, including the test suite
44  (section A.5) but excluding the rest of Appendix A. It does not include
45  any code or documentation that is identified in the RFC as being
46  copyrighted.

48  The original and principal author of md5.h is L. Peter Deutsch
49  <ghost@aladdin.com>. Other authors are noted in the change history
50  that follows (in reverse chronological order):
51 
52  2002-04-13 lpd Removed support for non-ANSI compilers; removed
53  references to Ghostscript; clarified derivation from RFC 1321;
54  now handles byte order either statically or dynamically.
55  1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
56  1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
57  added conditionalization for C++ compilation from Martin
58  Purschke <purschke@bnl.gov>.
59  1999-05-03 lpd Original version.
