1/*
2 * md5.h was taken from "RFC1321-based (RSA-free) MD5 library" by L. Peter
3 * Deutsch at http://sourceforge.net/projects/libmd5-rfc/ in October 2011.
4 *
5 * The code was not modified when integrated into the Dillo project, but you
6 * should check the source repository to be sure that there have not been
7 * modifications since this notice.

35 Independent implementation of MD5 (RFC 1321).
36
37 This code implements the MD5 Algorithm defined in RFC 1321, whose
38 text is available at
39 http://www.ietf.org/rfc/rfc1321.txt
40 The code is derived from the text of the RFC, including the test suite
41 (section A.5) but excluding the rest of Appendix A. It does not include
42 any code or documentation that is identified in the RFC as being
43 copyrighted.

45 The original and principal author of md5.h is L. Peter Deutsch
46 <ghost@aladdin.com>. Other authors are noted in the change history
47 that follows (in reverse chronological order):
48
49 2002-04-13 lpd Removed support for non-ANSI compilers; removed
50 references to Ghostscript; clarified derivation from RFC 1321;
51 now handles byte order either statically or dynamically.
52 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
53 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
54 added conditionalization for C++ compilation from Martin
55 Purschke <purschke@bnl.gov>.
56 1999-05-03 lpd Original version.

63 * This package supports both compile-time and run-time determination of CPU
64 * byte order. If ARCH_IS_BIG_ENDIAN is defined as 0, the code will be
65 * compiled to run only on little-endian CPUs; if ARCH_IS_BIG_ENDIAN is
66 * defined as non-zero, the code will be compiled to run only on big-endian
67 * CPUs; if ARCH_IS_BIG_ENDIAN is not defined, the code will be compiled to
68 * run on either big- or little-endian CPUs, but will run slightly less
69 * efficiently on either one than if ARCH_IS_BIG_ENDIAN is defined.
