Diffie-Hellman Key Exchange

The Diffie-Hellman Key Exchange is a method for two parties to securely share a secret key over a public channel. They each choose a private number and combine it with a common base number to create a value they share openly. By using their private numbers and the other's shared value, they can independently compute the same secret key without ever directly transmitting it. This key can then be used to encrypt communications, ensuring that even if someone intercepts the exchanged values, they cannot derive the secret key without knowing the private numbers.
