Messages are to be encoded using the RSA method, and the primes chosen are p = 13 and q = 23, so that n = pq = 299. The encryption exponent is e = 13. Thus, the public key is (299, 13). (i) Show that the decryption exponent d (the private key) is 61. (ii) Use the repeated squaring algorithm to find the encrypted form c of the message m = 84.
