Problem
Alice uses Bob's RSA public key (e = 17, it = 19519) to send a four-character message to Bob using the (A 4-, 0, B 4-) 1, Z 44 25) encoding scheme and encrypting each character separately. Eve intercepts the ciphertext (6625 0 2968 17863) and decrypts the message without factoring the modulus. Find the plaintext and explain why Eve could easily break the cyphertext.
