Establish a secure communication channel using key encryption

Python code for Diffie-Hellman key exchange

Code used for demonstrating the principle of Diffie-Hellman key exchange alghorithm with AES and SHA256.

The Diffie-Hellman algorithm is being used to establish a shared secret that can be used for secret communications while exchanging data over a public network using the elliptic curve to generate points and get the secret key using the parameters.
