Diffie-Hellman

Diffie-Hellman is a method that allows two people to securely share a secret over an insecure connection. Each person chooses a private number and combines it with a common public number using a special mathematical process. They then exchange the results. By applying their private number to the received value, both arrive at the same secret without revealing their private choices. This shared secret can then be used to encrypt future communication, ensuring privacy even if someone intercepts the initial exchange. It’s a fundamental technique used to establish secure keys over the internet.
