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