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 key is (299, 13). 13. Thus, the public (a) Use the repeated squaring algorithm to find the encrypted form c of the message m = 84. (b) Show that the decryption exponent d (the private key) is 61. (c) Verify that you obtain the original message after decryption. Use the repeated squaring algorithm.
