- Independent implementation of MD5 (RFC 1321).
- This code implements the MD5 Algorithm defined in RFC 1321, whose
- text is available at
- http://www.ietf.org/rfc/rfc1321.txt
- The code is derived from the text of the RFC, including the test suite
- (section A.5) but excluding the rest of Appendix A. It does not include
- any code or documentation that is identified in the RFC as being
- copyrighted.
- The original and principal author of md5.h is L. Peter Deutsch
- <ghost@aladdin.com>. Other authors are noted in the change history
- that follows (in reverse chronological order):
- 2002-04-13 lpd Removed support for non-ANSI compilers; removed
- references to Ghostscript; clarified derivation from RFC 1321;
- now handles byte order either statically or dynamically.
- 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
- 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
- added conditionalization for C++ compilation from Martin
- Purschke <purschke@bnl.gov>.
- 1999-05-03 lpd Original version.
