Consider a consequence of Euclid's Lemma: a,b,c Z, gcd (a,b) =1 Aa | bca | b and Fermat's Little Theorem: If p is any prime number and a is any integer such that p Xa⇒a=¹= 1 (mod p). Show how these statements are used to show an RSA cypher will work. It is possible in RSA cryptog- raphy to encode a cypher with (pq, e) as public key, by using C=Me (mod pq) and then decode the cypher with d=-e (mod (p-1) (q-1)), using M = Cd (mod pq)
