27 Independent implementation of MD5 (RFC 1321).
28
29 This code implements the MD5 Algorithm defined in RFC 1321, whose
30 text is available at
31 http://www.ietf.org/rfc/rfc1321.txt
32 The code is derived from the text of the RFC, including the test suite
33 (section A.5) but excluding the rest of Appendix A. It does not include
34 any code or documentation that is identified in the RFC as being
35 copyrighted.

37 The original and principal author of md5.h is L. Peter Deutsch
38 <ghost@aladdin.com>. Other authors are noted in the change history
39 that follows (in reverse chronological order):
40
41 2002-04-13 lpd Removed support for non-ANSI compilers; removed
42 references to Ghostscript; clarified derivation from RFC 1321;
43 now handles byte order either statically or dynamically.
44 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
45 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
46 added conditionalization for C++ compilation from Martin
47 Purschke <purschke@bnl.gov>.
48 1999-05-03 lpd Original version.

52 * This package supports both compile-time and run-time determination of CPU
53 * byte order. If ARCH_IS_BIG_ENDIAN is defined as 0, the code will be
54 * compiled to run only on little-endian CPUs; if ARCH_IS_BIG_ENDIAN is
55 * defined as non-zero, the code will be compiled to run only on big-endian
56 * CPUs; if ARCH_IS_BIG_ENDIAN is not defined, the code will be compiled to
57 * run on either big- or little-endian CPUs, but will run slightly less
58 * efficiently on either one than if ARCH_IS_BIG_ENDIAN is defined.
