SSL (Secure Sockets Layer) 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.
Client-server applications use the TLS protocol to communicate across a network in a way designed to prevent eavesdropping and tampering. The connection is private (or has confidentiality) because a symmetric-key algorithm is used to encrypt the data transmitted. [edit] Notes.
