Guide to the Diffie-Hellman Key Exchange Algorithm & its Working

WebDiffie-Hellman Key Exchange Algorithm. The Diffie-Hellman (DH) key exchange algorithm is a method used to make a shared encryption key available to two entities without an exchange of the key. The encryption key for the two devices is used as a symmetric key for encrypting data. Only the two parties involved in the DH key exchange can deduce ... WebJan 7, 2024 · The purpose of the Diffie-Hellman algorithm is to make it possible for two or more parties to create and share an identical, secret session key by sharing information over a network that is not secure. The information that gets shared over the network is in the form of a couple of constant values and a Diffie-Hellman public key.
