Encryption and decryption with Diffie-Hellman

WebIn the general case, for proper security with Diffie-Hellman, we need a value g such that the order of g (the smallest integer n ≥ 1 such that g n = 1 mod p) is a multiple of a large enough prime q. "Large enough" means "of length at least 2 t bits if we target t -bit security". Since n necessarily divides p − 1, q divides p − 1.
