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.
