OpenSSL is an open source implementation of the SSL and TLS protocols. A core library (written in the C programming language) implements the basic cryptographic functions and will bring various utility functions. Wrappers leaving the have of the OpenSSL library around a kind of computer-oriented language come available.

Versions come available for virtually all Unix-like operating systems (including Linux, Mac OS X and the quaternary open source BSD operating systems), and as well for Microsoft Windows. OpenSSL is according to SSLeay by Eric Young & Tim Hudson.

FIPS compliance
A Open Source Software Institute is attempting to secure the FIPS 140-2 validation for OpenSSL [http://oss-institute.org/fips-faq.html], for which the [http://oss-institute.org/index.php?option=content&task=view&id=39 current status is also available].

Misconceptions

Because of the prefix Open- in it's title, OpenSSL is typically associated by owning OpenBSD; which distributes several programmes using the appellative style of Open*, prefer OpenSSH. This is notwithstanding the mistake when OpenSSL is developed all outside of the scope of OpenBSD per OpenSSL Design, under the different license than is unremarkably utilized by OpenBSD. Rather by using FreeBSD's OpenBSM, the plan just shares the goal of with an open source implementation of a worthful plus for the commonweal.
