Generation

Forward secrecy is a property of cryptographic protocols that ensures session keys remain secure even if the server's long-term private key is later compromised. It works by generating ephemeral (temporary) key pairs for each session using algorithms like Diffie-Hellman, where both parties create temporary keys that are discarded after the session ends. The key formula is the Diffie-Hellman key exchange: **Shared secret = g^(ab) mod p**, where g is a generator, p is a prime, and a, b are the ephemeral private keys held by each party (computing g^a mod p and g^b mod p publicly). This ensures past communications cannot be decrypted retroactively since the ephemeral keys no longer exist.
