| 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. |
