157 Independent implementation of MD5 (RFC 1321).
158 This code implements the MD5 Algorithm defined in RFC 1321, whose
160 http://www.ietf.org/rfc/rfc1321.txt
161 The code is derived from the text of the RFC, including the test suite
162 (section A.5) but excluding the rest of Appendix A. It does not include
163 any code or documentation that is identified in the RFC as being
165 The original and principal author of md5.h is L. Peter Deutsch
166 <ghost@aladdin.com>. Other authors are noted in the change history
167 that follows (in reverse chronological order):
168 2002-04-13 lpd Removed support for non-ANSI compilers; removed
169 references to Ghostscript; clarified derivation from RFC 1321;
170 now handles byte order either statically or dynamically.
171 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
172 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
173 added conditionalization for C++ compilation from
174 Martin Purschke <purschke@bnl.gov>.
175 1999-05-03 lpd Original version.
179 * This package supports both compile-time and run-time determination of CPU
180 * byte order. If ARCH_IS_BIG_ENDIAN is defined as 0, the code will be
181 * compiled to run only on little-endian CPUs; if ARCH_IS_BIG_ENDIAN is
182 * defined as non-zero, the code will be compiled to run only on big-endian
183 * CPUs; if ARCH_IS_BIG_ENDIAN is not defined, the code will be compiled to
184 * run on either big- or little-endian CPUs, but will run slightly less
185 * efficiently on either one than if ARCH_IS_BIG_ENDIAN is defined.
