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.
|
||
|

|
||

|
||
|
|
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.
