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.
