Let the two primes p = 41 and q = 17 be given as set-up parameters for RSA. 1) Which of the parameters e1 = 32, e2 = 49 is a valid RSA exponent (i. e., is a valid public key, e1 or e2)? Justify your choice. 2) Compute the corresponding private key Kpr = (p, q, d). Use the extended Euclidean algorithm for the inversion and point out every calculation step.
