Note

OpenSSL is an open-source toolkit, which provides Secure Socket Layer (SSL) and Transport Layer Security (TLS) protocols, and also a general purpose cryptography library. More information can be found at: http://openssl.org.

The Secure Sockets Layer (SSL) protocol and its successor Transport Layer Security (TLS) are cryptographic protocols that provide secure communications on the Internet and the Intranet for various applications such as email, web browsing, printing, and so on.

GNU TLS is a project that provides security over the transport layer. More information can be found at: http://www.gnu.org/software/gnutls/. Common Data Security Architecture (CDSA) is a cryptographic framework and a set of security services, which provides encryption libraries for client-server environments.
