OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general-purpose cryptography library.

The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, fully featured, and Open Source toolkit implementing the Transport Layer Security (TLS) protocols (including SSLv3) as well as a full-strength general purpose cryptographic library.

The OpenSSL toolkit includes:

libssl (with platform specific naming):
         Provides the client and server-side implementations for SSLv3 and TLS.

libcrypto (with platform specific naming):
         Provides general cryptographic and X.509 support needed by SSL/TLS but
         not logically part of it.

         A command line tool that can be used for:
               Creation of key parameters
               Creation of X.509 certificates, CSRs and CRLs
               Calculation of message digests
               Encryption and decryption
               SSL/TLS client and server tests
               Handling of S/MIME signed or encrypted mail
               And more...
