WebClosed 6 years ago. I've been reading the same thing on a lot of websites: RSA is for communication using the public and private key for both the server and client, whereas Diffie-Hellman is just for exchanging the same secret key that will then be used for both encryption and decryption. But they both depend on the same math. Then I was ... Elliptic-curve Diffie–Hellman (ECDH) is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. This shared secret may be directly used as a key, or to derive another key. The key, or the derived key, can then be used to encrypt subsequent communications using a symmetric-key cipher. It is a variant of the Diffie–Hellman protocol using elliptic-curve cryptography.

WebDiffie-Hellman is the most secure key exchanged protocol and as such, it will generally be enabled by default.
