So I know d ⋅ e = 1(mod(p − 1)(q − 1)) for the primes p ≠ q that generate n by p ⋅ q = n but from here, how can I efficiency find p and q? And on the other way, I assume the answer is similar. If I know p and q, how can I generate d to crack the encryption? new homes for sale in nampa idaho https://rdhconsultancy.com
