Sure! Here is a step-by-step guide to the Diffie–Hellman Key Exchange that includes math equations and example applications:
1. Start by defining two large prime numbers, p and q, which will be used to generate the two keys.
2. Generate a random number, a, between 1 and q-1.
3. Calculate A = a^p mod q. This is the public key, NPUB1.
4. Calculate B = b^p mod q. This is the private key, NSEC1.
5. The two parties can then use the public and private keys to securely communicate with each other by encrypting and decrypting messages with the two keys. For example, Party A can use the public key (NPUB1) to encrypt a message and send it to Party B, and then Party B can use his/her private key (NSEC1) to decrypt the message.
6. The Diffie–Hellman Key Exchange is secure because the two keys (NPUB1 and NSEC1) can only be generated by the two parties participating in the exchange and are not visible to any outsiders.
