Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.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 publicly visible.

The publishing of TLS 1.3 and DTLS 1.3 obsoleted TLS 1.2 and DTLS 1.2. Note that there are known vulnerabilities in SSL 2.0 and SSL 3.0. In 2021, IETF published RFC 8996 also forbidding negotiation of TLS 1.0, TLS 1.1, and DTLS 1.0 due to known vulnerabilities. NIST SP 800-52 requires support of TLS 1.3 by January 2024.
TLS, sometimes called by its older name Secure Sockets Layer (SSL), is notable for being a part of HTTPS, a protocol for securely browsing the web. In a typical public-key infrastructure (PKI) scheme, the certificate issuer is a certificate authority (CA), [3] usually a company that charges customers a fee to issue certificates for them.
