In the RSA scheme with the public key (e, n) = (3, 21): a) (5 marks) encipher the plaintext M = 9; b) (5

In the RSA scheme with the public key (e, n) = (3, 21): a) (5 marks) encipher the plaintext M = 9; b) (5 marks) break the cipher by finding p, q and d, where n = p xq and (d, n) is the private key; c) (5 marks) decipher the ciphertext C = 3.
