| 26 Independent implementation of MD5 (RFC 1321). | |
| 27 | |
| 28 This code implements the MD5 Algorithm defined in RFC 1321, whose | |
| 29 text is available at | |
| 30 http://www.ietf.org/rfc/rfc1321.txt | |
| 31 The code is derived from the text of the RFC, including the test suite | |
| 32 (section A.5) but excluding the rest of Appendix A. It does not include | |
| 33 any code or documentation that is identified in the RFC as being | |
| 34 copyrighted. | |
| 35 | |
| 36 The original and principal author of md5.h is L. Peter Deutsch | |
| 37 <ghost@aladdin.com>. Other authors are noted in the change history | |
| 38 that follows (in reverse chronological order): | |
| 39 | |
| 40 2002-04-13 lpd Removed support for non-ANSI compilers; removed | |
| 41 references to Ghostscript; clarified derivation from RFC 1321; | |
| 42 now handles byte order either statically or dynamically. | |
| 43 1999-11-04 lpd Edited comments slightly for automatic TOC extraction. | |
| 44 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5); | |
| 45 added conditionalization for C++ compilation from Martin | |
| 46 Purschke <purschke@bnl.gov>. | |
| 47 1999-05-03 lpd Original version. | |
