WebJul 5, 2024 · Cracking the implementation. One thing we need to observe here is the relation between n and t_p. We can observe that t_p = 1mod (p) (Since all the other terms except 1 in the expansion of pow (s*p + 1, (d-1)/ (1 << r)) would be divisible by p) This means (t_p - 1) is a multiple of p. Since n is also a multiple of p, the GCD of (t_p - 1) and n ...
