**  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.
