In computer networking, OpenSSL is a software library to be used in applications that need to secure communications against eavesdropping or need to ascertain the identity of the party at the other end. It has found wide use in internet web servers, serving a majority of all web sites. OpenSSL contains an open-source implementation of the SSL and TLS protocols. The core library, written in the C programming language, implements basic cryptographic functions and provides various utility functions. Wrappers allowing the use of the OpenSSL library in a variety of computer languages are available. Versions are available for most Unix-like operating systems (including Solaris, Linux, Mac OS X and the various open-source BSD operating systems), OpenVMS and Microsoft Windows. IBM provides a port for the System i (OS/400). == Project history == The OpenSSL project was founded in 1998 to invent a free set of encryption tools for the code used on the Internet. It is based on a fork of SSLeay by Eric Andrew Young and Tim Hudson, development of which unofficially ended on December 17, 1998, when Young and Hudson both started to work for RSA Security. The OpenSSL project management team consists of four Europeans. The entire development group consists of 11 members, out of which 10 are volunteers; there is only one full-time employee, Stephen Henson, the lead developer.〔 The project has a budget of less than $1 million a year and relies in part on donations. Steve Marquess, a former CIA consultant in Maryland started the foundation for donations and consultancy contracts and garnered sponsorship from the United States Department of Homeland Security and the United States Department of Defense. In 2013, WikiLeaks published documents obtained by Edward Snowden which revealed that since 2010 the NSA had effectively broken/bypassed SSL/TLS by possibly exploiting vulnerabilities such as HeartBleed. As of 2014 two thirds of all webservers use OpenSSL. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「openssl」の詳細全文を読む スポンサード リンク
