Question: Messages are to be encoded using the RSA method, and the primes chosen are p = 11 and q = 19, so that n = pq = 209. The encryption exponent is e = 17. Thus, the public key is (209, 17). (i) Show that the decryption exponent d (the private key) is 53. (ii) Use the repeated squaring algorithm to find the encrypted form c of the message m = 47.

Question: Messages are to be encoded using the RSA method, and the primes chosen are
p = 11 and q = 19, so that n = pq = 209. The encryption exponent is e = 17.
Thus, the public key is (209, 17).
(i) Show that the decryption exponent d (the private key) is 53.
(ii) Use the repeated squaring algorithm to find the encrypted form c of the
message m = 47.
