Transport Layer Security (TLS), previously known as Secure Sockets Layer (SSL), is a protocol used by applications to communicate securely across a network, preventing tampering with and eavesdropping on email, web browsing, messaging, and other protocols.

All modern browsers support the TLS protocol, requiring the server to provide a valid digital certificate confirming its identity in order to establish a secure connection. It is possible for both the client and server to mutually authenticate each other, if both parties provide their own individual digital certificates.
