History of the software
|
|
=======================
|
|
|
|
Python was created in the early 1990s by Guido van Rossum at Stichting
|
|
Mathematisch Centrum (CWI, see https://www.cwi.nl/) in the Netherlands as a
|
|
successor of a language called ABC. Guido remains Python's principal author,
|
|
although it includes many contributions from others.
|
|
|
|
In 1995, Guido continued his work on Python at the Corporation for National
|
|
Research Initiatives (CNRI, see https://www.cnri.reston.va.us/) in Reston,
|
|
Virginia where he released several versions of the software.
|
|
|
|
In May 2000, Guido and the Python core development team moved to BeOpen.com to
|
|
form the BeOpen PythonLabs team. In October of the same year, the PythonLabs
|
|
team moved to Digital Creations (now Zope Corporation; see
|
|
http://www.zope.com/). In 2001, the Python Software Foundation (PSF, see
|
|
https://www.python.org/psf/) was formed, a non-profit organization created
|
|
specifically to own Python-related Intellectual Property. Zope Corporation is a
|
|
sponsoring member of the PSF.
|
|
|
|
All Python releases are Open Source (see https://opensource.org/ for the Open
|
|
Source Definition). Historically, most, but not all, Python releases have also
|
|
been GPL-compatible; the table below summarizes the various releases.

.. note::
|
|
|
|
GPL-compatible doesn't mean that we're distributing Python under the GPL. All
|
|
Python licenses, unlike the GPL, let you distribute a modified version without
|
|
making your changes open source. The GPL-compatible licenses make it possible to
|
|
combine Python with other software that is released under the GPL; the others
|
|
don't.
|
|
|
|
Thanks to the many outside volunteers who have worked under Guido's direction to
|
|
make these releases possible.

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
|

<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;
|
|

|
|
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>.
|
|

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

OpenSSL
|
|
-------
|
|
|
|
The modules :mod:`hashlib`, :mod:`posix`, :mod:`ssl`, :mod:`crypt` use
|
|
the OpenSSL library for added performance if made available by the
|
|
operating system. Additionally, the Windows and Mac OS X installers for
|
|
Python may include a copy of the OpenSSL libraries, so we include a copy
|
|
of the OpenSSL license here::

LICENSE ISSUES
|
|
==============
|
|
|
|
The OpenSSL toolkit stays under a dual license, i.e. both the conditions of
|
|
the OpenSSL License and the original SSLeay license apply to the toolkit.
|
|
See below for the actual license texts. Actually both licenses are BSD-style
|
|
Open Source licenses. In case of any license issues related to OpenSSL
