Diffie-Hellman function

The Diffie-Hellman function is a method that allows two parties to securely create a shared secret over an insecure communication channel. Each person chooses a private number and computes a value using a common public number (like a base and a prime). They exchange these computed values, then each uses their private number and the received value to independently generate the same secret key. This shared secret can then be used for encrypted communication, ensuring that even if others see the exchanged values, they cannot determine the secret without knowing the private numbers.
