Independent implementation of MD5 (RFC 1321).
This is the code implements the MD5 algorithm defined in RFC 1321.
It is derived directly from the text of the RFC and not
Reference implementation.
The original and principal author of Md5.h is L. Peter Deutsch
<ghost@aladdin.com>. The other authors are noted on 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);
Added conditionalization for C + + compilation from Martin
Purschke <purschke@bnl.gov>
1999-05-03 LPD Original version.
