Because they are harder to decipher, attacks against cyphers are made more difficult when the message being encrypted is shorter.
Encrypt the message DEFEND using the RSA system with n = 43*59 and e = 13. First translate each letter into an integer and group together pairs of integers, so you have three 4-digit numbers (padding 0’s in the front if necessary). Work with each of these numbers to encrypt them. The ciphertext should also be three 4-digit numbers.
