Transport Layer Security (TLS), defined by IETF in 1999, is a cryptographic protocol used to encrypt communication over the Internet. Secure Sockets Layer (SSL) has the same purpose.
Both protocols use asymmetric cryptography for authentification of key exchange, to ensure message integrity and confidentiality.
They are used in applications such as email, instant messaging, and voice-over IP. It is also the security layer in HTTPS.
