WebDiffie-Hellman java implementation In order to perform the Diffie-Hellman key exchange, the program does the following: Generates a random 1023-bit integer: this will be private key b. Generate public key B given by gb (mod p) Calculate the shared key s given by Ab (mod p) 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.
