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.

TLS may refer to: Computing. Transport Layer Security, a cryptographic protocol for secure computer network communication; Thread level speculation, ...
It uses encryption for secure communication over a computer network, and is widely used on the Internet. [1] [2] In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL). The protocol is therefore also referred to as HTTP over TLS, [3] or HTTP over SSL.
Transport Layer Security (TLS) requires a handshake of its own for key exchange at connection establishment. Because of the layered design, the TCP handshake and the TLS handshake proceed serially; the TLS handshake cannot begin until the TCP handshake has concluded. [113] Two RTTs are required for connection establishment with TLS 1.2 over TCP ...
Rustls (pronounced "rustles" [3]) is an open-source implementation of the Transport Layer Security (TLS) cryptographic protocol written in the Rust programming language.TLS is essential to internet security, and Rustls aims to enable secure, fast TLS connections.
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.
Network Security Services (NSS) is a collection of cryptographic computer libraries designed to support cross-platform development of security-enabled client and server applications with optional support for hardware TLS/SSL acceleration on the server side and hardware smart cards on the client side.
