 * 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.h 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 Removed support for non-ANSI compilers; removed references to
 * Ghostscript; clarified derivation from RFC 1321; now handles byte order
 * either statically or dynamically. 1999-11-04 lpd Edited comments slightly
 * for automatic TOC extraction. 1999-10-18 lpd Fixed typo in header comment
 * (ansi2knr rather than md5); added conditionalization for C++ compilation
 * from Martin Purschke <purschke@bnl.gov>. 1999-05-03 lpd Original version.

 * defined as non-zero, the code will be compiled to run only on big-endian
 * CPUs; if ARCH_IS_BIG_ENDIAN is not defined, the code will be compiled to
 * run on either big- or little-endian CPUs, but will run slightly less
 * efficiently on either one than if ARCH_IS_BIG_ENDIAN is defined.
