The newly published RFC 10015 officially deprecates RSA and finite field Diffie-Hellman key exchange methods for TLS 1.2 and DTLS 1.2 connections. The update also discourages the use of static Elliptic Curve Diffie-Hellman cipher suites to further strengthen protocol security. These cryptographic changes apply exclusively to version 1.2, as older protocol versions are already deprecated and TLS 1.3 does not utilize these algorithms.
