209 Independent implementation of MD5 (RFC 1321).
211 This code implements the MD5 Algorithm defined in RFC 1321, whose
212 text is available at
213 http://www.ietf.org/rfc/rfc1321.txt
214 The code is derived from the text of the RFC, including the test suite
215 (section A.5) but excluding the rest of Appendix A. It does not include
216 any code or documentation that is identified in the RFC as being
217 copyrighted.
219 The original and principal author of md5.h is L. Peter Deutsch
220 <ghost@aladdin.com>. Other authors are noted in the change history
221 that follows (in reverse chronological order):
223 2002-04-13 lpd Removed support for non-ANSI compilers; removed
224 references to Ghostscript; clarified derivation from RFC 1321;
225 now handles byte order either statically or dynamically.
226 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
227 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
228 added conditionalization for C++ compilation from Martin
229 Purschke <purschke@bnl.gov>.
230 1999-05-03 lpd Original version.

344 Modified by Jack Jansen, CWI, July 1995:
345 - Use binascii module to do the actual line-by-line conversion
346 between ascii and binary. This results in a 1000-fold speedup. The C
347 version is still 5 times faster, though.
348 - Arguments more compliant with Python standard
