WebIn Diffie-Hellman, computations occur modulo a big prime p, and the resulting shared secret is an integer modulo p, i.e. a value ranging from 0 to p-1. This value has some "structure" so you should not truncate it blindly. The "safe" way is to apply a hash function on an encoding of that value, for instance SHA-256. fd6000a motorWebJun 19, 2024 · Diffie-Hellman (DH), also known as an exponential key exchange, was published in 1976.
