TLS

First defined in 1999, TLS, also known as transport layer security, is a type of cryptographic protocol which provides secure communications over computer networks. The TLS protocol is the successor to SSL (secure sockets layer) and uses asymmetric encryption methods to perform authentication, and then exchange a symmetric key to encrypt the data that passes over the network.

Transport Layer Security protocols are used in everyday networking operations like secure web browsing, e-mail, instant messaging, and VoIP (Voice over Internet Protocol).

How do I know if I'm using TLS in a browser?

Secure websites using TLS can be identified by looking for a lock next to the URL (uniform resource locator) or a URL starting with "https" instead of "http."
