WebTo enhance portability to python 3 use // instead of / everywhere in your code. You already do this in lines like q //= 2, but not in lines like x = pow(a, (p + 1)/4, p).In fact, consider including from __future__ import division..

WebHowever, I would also add that, for Diffie-Hellman, you don't need a primitive element of the group. Instead, you want an element that generates a large prime order; my answer in For Diffie-Hellman, must g be a generator? explains why. WebFeb 3, 2024 · If the multiplicative order of a number r modulo n is equal to Euler Totient Function Φ (n) ( note that the Euler Totient Function for a prime n is n-1), then it is a …

Im not sure if this should go in the math/number theory section or here, but here it goes: how do programs calculate the primitive roots mod n of extremely large primes? WebAug 26, 2015 · What Matlab does in this case is it calculates a^((p-1)/p) before taking the modulus. As a^((p-1)/p) quite quickly becomes too large to handle, Matlab seems to resolve this by turning it into a floating point number, losing some resolution and yielding the wrong result when you take the modulus.. As mentioned by @rayreng, you could use an arbitrary …
