One of the attacks an intruder can apply to a simple cipher like an additive cipher is called the ciphertext attack. In this type of attack, the intruder intercepts the cipher and tries to find the key and eventually the plaintext. One of the methods used in a ciphertext attack is called the brute-force approach, in which the intruder tries several keys and decrypts the message until the message makes sense. Assume the intruder has intercepted the ciphertext "UVACLYZLJBYL". Try to decrypt the message by using keys beginning with 1 and continuing until a plaintext appears that makes sense.
