[138] [139] RFC 7465 prohibits the use of RC4 cipher suites in all versions of TLS. On September 1, 2015, Microsoft, Google, and Mozilla announced that RC4 cipher suites would be disabled by default in their browsers (Microsoft Edge [Legacy], Internet Explorer 11 on Windows 7/8.1/10, Firefox, and Chrome) in early 2016. [140] [141] [142]
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.
The newest version of TLS (TLS 1.3) includes additional requirements to cipher suites. Cipher suites defined for TLS 1.2 cannot be used in TLS 1.3, and vice versa, unless otherwise stated in their definition. A reference list of named cipher suites is provided in the TLS Cipher Suite Registry. [4]

TLS-PSK uses symmetric keys, shared in advance among the communicating parties, to establish a TLS connection. There are several reasons to use PSKs: Using pre-shared keys can, depending on the ciphersuite, avoid the need for public key operations. This is useful if TLS is used in performance-constrained environments with limited CPU power.

The outcome of this process was the adoption of Adam Langley's proposal for a variant of the original ChaCha20 algorithm (using 32-bit counter and 96-bit nonce) and a variant of the original Poly1305 (authenticating 2 strings) being combined in an IETF draft [5] [6] to be used in TLS and DTLS, [7] and chosen, for security and performance ...
