title: Solve the d key given the n and e key for RSA
body: <p>I have been given the task by my teacher, to try to find the d key for RSA, if the n and e keys have been given to you. How would you do this? My assumption would be that first you need to find phi(n), then, using the formula d = (kt+1)/e, find k and d? How exactly can you solve for phi(n), and also k and d?</p>
