DH is one of the earliest practical examples of public key …

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. WebSep 23, 2015 · It's simple: pow takes an optional 3rd argument for the modulus. From the docs: pow (x, y [, z]) Return x to the power y; if z is present, return x to the power y, modulo z (computed more efficiently than pow (x, y) % z). The two-argument form pow (x, y) is equivalent to using the power operator: x**y. So you want: pow (6, 8, 5)
