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.

<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.
