The original 2006 release of DTLS version 1.0 was not a standalone document. It was given as a series of deltas to TLS 1.1. [11] Similarly the follow-up 2012 release of DTLS is a delta to TLS 1.2. It was given the version number of DTLS 1.2 to match its TLS version. Lastly, the 2022 DTLS 1.3 is a delta to TLS 1.3.

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. Support of TLS 1.3 means ...

Encrypted Client Hello (ECH) is a TLS 1.3 protocol extension that enables encryption of the whole Client Hello message, which is sent during the early stage of TLS 1.3 negotiation. [10] ECH encrypts the payload with a public key that the relying party (a web browser) needs to know in advance, which means ECH is most effective with large CDNs ...
GnuTLS (/ ˈ ɡ n uː ˌ t iː ˌ ɛ l ˈ ɛ s /, the GNU Transport Layer Security Library) is a free software implementation of the TLS, SSL and DTLS protocols. It offers an application programming interface (API) for applications to enable secure communication over the network transport layer, as well as interfaces to access X.509, PKCS #12, OpenPGP and other structures.
Go (in the standard library crypto/tls package) since version 1.4 released in December 2014 [9] JSSE in Java since JDK 9 released in September 2017, [10] backported to JDK 8 released in April 2020 [11] Win32 SSPI since Windows 8.1 and Windows Server 2012 R2 were released October 18, 2013 [12]
It is also supported by major web servers over Transport Layer Security (TLS) using an Application-Layer Protocol Negotiation (ALPN) extension [10] where TLS 1.2 or newer is required. [11] [12] HTTP/3, the successor to HTTP/2, was published in 2022. [13]
