** 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.
