A workaround for SSL 3.0 and TLS 1.0, roughly equivalent to random IVs from TLS 1.1, was widely adopted by many implementations in late 2011. [30] In 2014, the POODLE vulnerability of SSL 3.0 was discovered, which takes advantage of the known vulnerabilities in CBC, and an insecure fallback negotiation used in browsers. [31]

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 ...
Both the client and the server must support the agreed upon cipher suite. If the client and server do not agree on a cipher suite, no connection will be made. [8] This selection process occurs during the TLS Handshake Protocol. TLS 1.3 includes a TLS Handshake Protocol that differs compared to past and the current version of TLS/SSL.

The PCI Council suggested that organizations migrate from TLS 1.0 to TLS 1.1 or higher before June 30, 2018. [41] [42] In October 2018, Apple, Google, Microsoft, and Mozilla jointly announced they would deprecate TLS 1.0 and 1.1 in March 2020. [20] TLS 1.0 and 1.1 were formally deprecated in RFC 8996 in March 2021.
ZScaler tunnel 2.0 uses DTLS for tunneling. [39] F5 Networks Edge VPN Client uses TLS and DTLS. [40] Fortinet's SSL VPN [41] and Array Networks SSL VPN [42] also use DTLS for VPN tunneling. Citrix Systems NetScaler uses DTLS to secure UDP. [43] Web browsers: Google Chrome, Opera and Firefox support DTLS-SRTP [44] for WebRTC. Firefox 86 and ...
HTTP/2 (originally named HTTP/2.0) is a major revision of the HTTP network protocol used by the World Wide Web. It was derived from the earlier experimental SPDY protocol, originally developed by Google .
