TLS (transport layer security) Cryptographic protocols for securing data in transit Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most well known. The closely related Datagram Transport Layer Security (DTLS) is a communications protocol that provides security to datagram-based applications.
In technical writing, references to "(D)TLS" are often seen when it applies to both versions.[1] TLS is a proposed Internet Engineering Task Force (IETF) standard, first defined in 1999, and the current version is TLS 1.3, defined in August 2018. TLS builds on the now-deprecated SSL (Secure Sockets Layer) specifications (1994, 1995, 1996) developed by Netscape Communications for adding the HTTPS protocol to their Netscape Navigator web browser.
