| 10 | History of the software |
| 11 | ======================= |
| 12 | |
| 13 | Python was created in the early 1990s by Guido van Rossum at Stichting |
| 14 | Mathematisch Centrum (CWI, see http://www.cwi.nl/) in the Netherlands as a |
| 15 | successor of a language called ABC. Guido remains Python's principal author, |
| 16 | although it includes many contributions from others. |
| 17 | |
| 18 | In 1995, Guido continued his work on Python at the Corporation for National |
| 19 | Research Initiatives (CNRI, see http://www.cnri.reston.va.us/) in Reston, |
| 20 | Virginia where he released several versions of the software. |
| 21 | |
| 22 | In May 2000, Guido and the Python core development team moved to BeOpen.com to |
| 23 | form the BeOpen PythonLabs team. In October of the same year, the PythonLabs |
| 24 | team moved to Digital Creations (now Zope Corporation; see |
| 25 | http://www.zope.com/). In 2001, the Python Software Foundation (PSF, see |
| 26 | http://www.python.org/psf/) was formed, a non-profit organization created |
| 27 | specifically to own Python-related Intellectual Property. Zope Corporation is a |
| 28 | sponsoring member of the PSF. |
| 29 | |
| 30 | All Python releases are Open Source (see http://www.opensource.org/ for the Open |
| 31 | Source Definition). Historically, most, but not all, Python releases have also |
| 32 | been GPL-compatible; the table below summarizes the various releases. |

| 100 | .. note:: |
| 101 | |
| 102 | GPL-compatible doesn't mean that we're distributing Python under the GPL. All |
| 103 | Python licenses, unlike the GPL, let you distribute a modified version without |
| 104 | making your changes open source. The GPL-compatible licenses make it possible to |
| 105 | combine Python with other software that is released under the GPL; the others |
| 106 | don't. |
| 107 | |
| 108 | Thanks to the many outside volunteers who have worked under Guido's direction to |
| 109 | make these releases possible. |

| 452 | Independent implementation of MD5 (RFC 1321). |
| 453 | |
| 454 | This code implements the MD5 Algorithm defined in RFC 1321, whose |
| 455 | text is available at |
Georg Brandl | 7044b11 | 2009-01-03 21:04:55 +0000 | [diff] [blame] | 456 | http://www.ietf.org/rfc/rfc1321.txt |
Georg Brandl | 8ec7f65 | 2007-08-15 14:28:01 +0000 | [diff] [blame] | 457 | The code is derived from the text of the RFC, including the test suite |
| 458 | (section A.5) but excluding the rest of Appendix A. It does not include |

| 460 | copyrighted. |

| 464 | that follows (in reverse chronological order): |
| 465 | |
| 466 | 2002-04-13 lpd Removed support for non-ANSI compilers; removed |
Georg Brandl | 7044b11 | 2009-01-03 21:04:55 +0000 | [diff] [blame] | 467 | references to Ghostscript; clarified derivation from RFC 1321; |
| 468 | now handles byte order either statically or dynamically. |
Georg Brandl | 8ec7f65 | 2007-08-15 14:28:01 +0000 | [diff] [blame] | 469 | 1999-11-04 lpd Edited comments slightly for automatic TOC extraction. |
| 470 | 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5); |
Georg Brandl | 7044b11 | 2009-01-03 21:04:55 +0000 | [diff] [blame] | 471 | added conditionalization for C++ compilation from Martin |
| 472 | Purschke <purschke@bnl.gov>. |

| 617 | Modified by Jack Jansen, CWI, July 1995: |
| 618 | - Use binascii module to do the actual line-by-line conversion |

| 620 | version is still 5 times faster, though. |
