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), the cryptography library developed by Mozilla and used by its web browser Firefox, enabled TLS 1.3 by default in February 2017. [49] TLS 1.3 support was subsequently added — but due to compatibility issues for a small number of users, not automatically enabled [50] — to Firefox 52.0, which was released in ...
TLS is essential to internet security, and Rustls aims to enable secure, fast TLS connections. Rustls uses Rust's enforcement of memory safety to reduce the risk of security vulnerabilities . It is part of efforts to improve internet security by replacing memory-unsafe software libraries , such as OpenSSL , with memory-safe alternatives.
Extensions: Server Name Indication (SNI), Maximum Fragment Length, Truncated HMAC, Application Layer Protocol Negotiation (ALPN), Extended Master Secret Ciphersuites: TLS Secure Remote Password , TLS Pre-Shared Key
Firefox 27 has added SPDY 3.1 support. [30] Firefox 28 has removed support of SPDY 2. [24] about:networking (or the HTTP/2 and SPDY indicator add-on) [47] shows if a website uses SPDY. Opera browser added support for SPDY as of version 12.10. [48] Internet Explorer 11 added support for SPDY version 3, [49] [50] but not for the Windows 7 version ...
HTTPS Everywhere was inspired by Google's increased use of HTTPS [8] and is designed to force the usage of HTTPS automatically whenever possible. [9] The code, in part, is based on NoScript's HTTP Strict Transport Security implementation, but HTTPS Everywhere is intended to be simpler to use than No Script's forced HTTPS functionality which requires the user to manually add websites to a list.

The style used to specify how to use TLS matches the same layer distinction that is also conveniently supported by several library implementations of TLS. E.g., the RFC 3207 SMTP extension illustrates with the following dialog how a client and server can start a secure session: [3]
