Alice received the following encrypted message, "10 21 52 26." Bob encrypted the message using an RSA cipher with public key (pq, e) = (55, 3). Alice's private key is 27. Find the residues needed to decipher each block of the ciphertext. 1027 ≡ (mod 55) 2127 ≡ (mod 55) 5227 ≡ (mod 55) 2627 ≡ (mod 55) What is the message after Alice decrypts it? (Assume Bob encoded one letter at a time. Assume Bob encoded the letters of the alphabet as follows: A = 01, B = 02, C = 03, …, Z = 26.)
