3Python was created in the early 1990s by Guido van Rossum at Stichting
Fred Drake0068e9c2001-07-17 23:08:24 +00004Mathematisch Centrum (CWI, see \url{http://www.cwi.nl/}) in the Netherlands
5as a successor of a language called ABC. Guido remains Python's
6principal author, although it includes many contributions from others.
Fred Drake852f7952001-06-20 21:34:35 +00007
Fred Drake0068e9c2001-07-17 23:08:24 +00008In 1995, Guido continued his work on Python at the Corporation for
9National Research Initiatives (CNRI, see \url{http://www.cnri.reston.va.us/})
10in Reston, Virginia where he released several versions of the
11software.
Fred Drake852f7952001-06-20 21:34:35 +000012
Fred Drake0068e9c2001-07-17 23:08:24 +000013In May 2000, Guido and the Python core development team moved to
14BeOpen.com to form the BeOpen PythonLabs team. In October of the same
Guido van Rossum2e1c09c2002-04-04 17:52:50 +000015year, the PythonLabs team moved to Digital Creations (now Zope
16Corporation; see \url{http://www.zope.com/}). In 2001, the Python
Fred Drake7b822712001-12-14 16:42:56 +000017Software Foundation (PSF, see \url{http://www.python.org/psf/}) was
18formed, a non-profit organization created specifically to own
Guido van Rossum2e1c09c2002-04-04 17:52:50 +000019Python-related Intellectual Property. Zope Corporation is a
Fred Drake7b822712001-12-14 16:42:56 +000020sponsoring member of the PSF.
Fred Drake0068e9c2001-07-17 23:08:24 +000021
22All Python releases are Open Source (see
23\url{http://www.opensource.org/} for the Open Source Definition).
24Historically, most, but not all, Python releases have also been
25GPL-compatible; the table below summarizes the various releases.

Fred Drake0068e9c2001-07-17 23:08:24 +000059Python under the GPL. All Python licenses, unlike the GPL, let you
60distribute a modified version without making your changes open source.
61The GPL-compatible licenses make it possible to combine Python with
Fred Drake0aa811c2001-10-20 04:24:09 +000062other software that is released under the GPL; the others don't.}
Fred Drake852f7952001-06-20 21:34:35 +000063
64Thanks to the many outside volunteers who have worked under Guido's
65direction to make these releases possible.

458 Independent implementation of MD5 (RFC 1321).
459
460 This code implements the MD5 Algorithm defined in RFC 1321, whose
461 text is available at
462 http://www.ietf.org/rfc/rfc1321.txt
463 The code is derived from the text of the RFC, including the test suite
464 (section A.5) but excluding the rest of Appendix A. It does not include
465 any code or documentation that is identified in the RFC as being
466 copyrighted.
467
468 The original and principal author of md5.h is L. Peter Deutsch
469 <ghost@aladdin.com>. Other authors are noted in the change history
470 that follows (in reverse chronological order):
471
472 2002-04-13 lpd Removed support for non-ANSI compilers; removed
473 references to Ghostscript; clarified derivation from RFC 1321;
474 now handles byte order either statically or dynamically.
475 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
476 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
477 added conditionalization for C++ compilation from Martin
478 Purschke <purschke@bnl.gov>.
479 1999-05-03 lpd Original version.

637 version is still 5 times faster, though.
638 - Arguments more compliant with python standard
