WebFeb 29, 2024 · In TLS 1.2, keys can be exchanged via RSA, DH (Diffie-Hellman over a Finite Field), ECDH (Diffie-Hellman over an Elliptic Curve), DHE (DH but the key is discarded after use to provide forward-secrecy), ECDHE (ECDH but the key is discarded after use to provide forward secrecy), PSK (Pre-Shared keys), and SRP (Secure Remote Password protocol).
