"WebDiffie-Hellman (DH) Key Exchange is one of the earliest Public Key Cryptosystem. The protocol uses a public key to securely exchange the private key. Although it is a Public Key Cryptosystem, the main goal of this protocol is to exchange a key (a.k.a. shared secret), so the two users can then encrypt the information using symmetric encryption.

WebDiffie–Hellman Key Exchange (DHKE) is a cryptographic method to securely exchange cryptographic keys (key agreement protocol) over a public (insecure) channel in a way that overheard communication does not reveal the keys. The exchanged keys are used later for encrypted communication (e.g. using a symmetric cipher like AES).
