[**Diffie–Hellman Key Exchange**](https://en.wikipedia.org/wiki/Diffie–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 \(e.g. using a symmetric cipher like AES\).

**DHKE** was one of the first **public-key protocols**, which allows two parties to exchange data securely, so that is someone sniffs the communication between the parties, the information exchanged can be revealed.

The Diffie–Hellman \(DH\) method is **anonymous key agreement scheme**: it allows two parties that have no prior knowledge of each other to jointly establish a **shared secret key over an insecure channel**.
