- Independent implementation of MD5 (RFC 1321).
- This code implements the MD5 Algorithm defined in RFC 1321.
- It is derived directly from the text of the RFC and not from the
- reference implementation.
- 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):
- 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.
