, 16:35, 14 February 2019→TLS 1.3
* All handshake messages after the ServerHello are now encrypted. The newly introduced EncryptedExtension message allows various extensions previously sent in clear in the ServerHello to also enjoy confidentiality protection from active attackers.

* The key derivation functions have been re-designed. The new design allows easier analysis by cryptographers due to their improved key separation properties. The HMAC-based Extract-and-Expand Key Derivation Function (HKDF) is used as an underlying primitive.

* Elliptic curve algorithms are now in the base spec and new signature algorithms. Recommended curve algorithms are found in the table below.

* The TLS 1.2 version negotiation mechanism has been deprecated in favor of a version list in an extension. This increases compatibility with existing servers that incorrectly implemented version negotiation.

* Session resumption with and without server-side state as well as the Pre-Shared Key (PSK)-based cipher suites of earlier TLS versions have been replaced by a single new PSK exchange.

* Updated references to point to the updated versions of RFCs, as appropriate (e.g., RFC 5280 rather than RFC 3280).
