Generation

# Diffie-Hellman Key Exchange Diffie-Hellman allows two parties to create a shared secret key over a public channel without ever directly transmitting the key itself. Both parties agree on public parameters (a prime number and a base), then each generates a private random number and performs modular exponentiation to create a public value they exchange. Each party then combines their own private number with the other's public value through another modular exponentiation, and remarkably, both arrive at the same shared secret—which an eavesdropper cannot easily compute due to the difficulty of the discrete logarithm problem. This shared secret can then be used as an encryption key for secure communication.
