In this article, we would implement the Diffie-Hellman Key Exchange algorithm in Python. In the last article, we explained how to implement the Diffie-Hellman Key Exchange algorithm using the pyDHE Python library. But, in this article, we would not use any Python library specific to the Diffie-Hellman Key Exchange algorithm and instead implement the algorithm using simple Python code.

We have already discussed in detail how the Diffie-Hellman Key Exchange algorithm works. In this article, we would implement the same algorithm.

Firstly, we would need a client that will establish a connection with a server. The server and the client will exchange shared parameters. And, based on the shared parameters, the shared secret will be calculated both at the client-side and the server-side.
