历史和许可证

软件的历史

Python 是由 Guido van Rossum 在 1990 年代初期在荷兰的 Stichting Mathematisch Centrum(CWI,参见 https://www.cwi.nl/)创建的,作为一种称为 ABC 的语言的继承者。 Guido 仍然是 Python 的主要作者,尽管它包含了许多其他人的贡献。

1995 年,Guido 在弗吉尼亚州雷斯顿的国家研究计划公司(CNRI,参见 https://www.cnri.reston.va.us/)继续他的 Python 工作,在那里他发布了多个版本的软件。

2000 年 5 月,Guido 和 Python 核心开发团队搬到 BeOpen.com,组成 BeOpen PythonLabs 团队。 同年 10 月,PythonLabs 团队转移到 Digital Creations(现在的 Zope Corporation;参见 https://www.zope.org/)。 2001 年,Python 软件基金会(PSF,参见 https://www.python.org/psf/)成立,这是一个专门为拥有 Python 相关知识产权而创建的非营利组织。 Zope Corporation 是 PSF 的赞助成员。

所有 Python 版本都是开源的(开源定义见 https://opensource.org/)。 从历史上看,大多数(但不是全部)Python 版本也与 GPL 兼容。 下表总结了各种版本。

发布 源自 所有者 GPL 兼容吗?
0.9.0 到 1.2 不适用 1991-1995 CWI 是的
1.3 到 1.5.2 1.2 1995-1999 中国研究院 是的
1.6 1.5.2 2000 中国研究院
2.0 1.6 2000 BeOpen.com
1.6.1 1.6 2001 中国研究院
2.1 2.0+1.6.1 2001 聚苯乙烯
2.0.1 2.0+1.6.1 2001 聚苯乙烯 是的
2.1.1 2.1+2.0.1 2001 聚苯乙烯 是的
2.1.2 2.1.1 2002 聚苯乙烯 是的
2.1.3 2.1.2 2002 聚苯乙烯 是的
2.2及以上 2.1.1 2001年至今 聚苯乙烯 是的

笔记

GPL 兼容并不意味着我们在 GPL 下分发 Python。 与 GPL 不同,所有 Python 许可证都允许您分发修改后的版本,而无需将更改开源。 GPL 兼容的许可证使得将 Python 与在 GPL 下发布的其他软件结合起来成为可能; 其他人没有。


感谢在 Guido 的指导下工作的许多外部志愿者使这些版本成为可能。

Independent implementation of MD5 (RFC 1321).

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
copyrighted.

The original and principal author of md5.h is L. Peter Deutsch
<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;
      now handles byte order either statically or dynamically.
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>.
1999-05-03 lpd Original version.

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

开放式SSL

如果操作系统可用,模块 hashlibposixsslcrypt 使用 OpenSSL 库来提高性能。 此外,用于 Python 的 Windows 和 Mac OS X 安装程序可能包含 OpenSSL 库的副本,因此我们在此处包含 OpenSSL 许可证的副本:

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
please contact openssl-core@openssl.org.
