26 | Independent implementation of MD5 (RFC 1321).\r | |
27 | \r | |
28 | This code implements the MD5 Algorithm defined in RFC 1321, whose\r | |
29 | text is available at\r | |
30 | http://www.ietf.org/rfc/rfc1321.txt\r | |
31 | The code is derived from the text of the RFC, including the test suite\r | |
32 | (section A.5) but excluding the rest of Appendix A. It does not include\r | |
33 | any code or documentation that is identified in the RFC as being\r | |
34 | copyrighted.\r | |

36 | The original and principal author of md5.h is L. Peter Deutsch\r | |
37 | <ghost@aladdin.com>. Other authors are noted in the change history\r | |
38 | that follows (in reverse chronological order):\r | |
39 | \r | |
40 | 2002-04-13 lpd Removed support for non-ANSI compilers; removed\r | |
41 | references to Ghostscript; clarified derivation from RFC 1321;\r | |
42 | now handles byte order either statically or dynamically.\r | |
43 | 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.\r | |
44 | 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);\r | |
45 | added conditionalization for C++ compilation from Martin\r | |
46 | Purschke <purschke@bnl.gov>.\r | |
47 | 1999-05-03 lpd Original version.\r | |
