Transport Layer Security (TLS) is a cryptographic protocol used for building a secure connection between a client and a server over the Internet. TLS is nowadays used for protecting web browsing, email, messaging, voice over IP, industrial automation systems, etc. As an example, TLS is essentially the "S" in HTTPS in secure web browsing.

When a TLS connection is opened, a handshake protocol authenticates the server (and optionally the client) and derives shared secret keys. These keys are then used to protect further communication so that it remains private from eavesdroppers as well as protected from any accidental or intentional manipulation. The TLS protocol is based on a combination of both symmetric and asymmetric cryptography — including cryptographic hash functions — and digital certificates. The latest and most secure version of TLS is 1.3 which was released in 2018 and standardized in RFC 8446.
