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.c 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 Clarified derivation from RFC 1321; now handles byte order
|
||||
either statically or dynamically; added missing #include <string.h>
|
||||
in library.
|
||||
2002-03-11 lpd Corrected argument list for main(), and added int return
|
||||
type, in test program and T value program.
|
||||
2002-02-21 lpd Added missing #include <stdio.h> in test program.
|
||||
2000-07-03 lpd Patched to eliminate warnings about "constant is
|
||||
unsigned in ANSI C, signed in traditional"; made test program
|
||||
self-checking.
|
||||
1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
|
||||
1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).
|
||||
1999-05-03 lpd Original version.
