Transport layer security (TLS)

Transport Layer Security (TLS) is a cryptographic protocol that provides security for communication over a computer network. Like its predecessor Secure Socket Layer (SSL), TLS  is used widely in web browsing, email, Internet faxing, instant messaging, and voice-over-IP (VoIP). TLS supports many different methods for exchanging keys, encrypting data, and authenticating message integrity that allow websites to secure all communications between their servers and web browsers.
