+/*
+ 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.
