$2.($a$)$ Given that the ciphertext EBO was encrypted using a shif t$($n$)$

cipher and that the plaintext is an English word, if you use a brute

force key search to try to decrypt it$,$ you will run into an ambiguity.

Describe what the issue is$.$

$($b$)$ Is the issue in part $($a$)$ resolved if you find out that the plaintext

is a proper first name rather than a word? Explain.

$($c$)$ Compare and contrast the decryption of this message with the

decryption you did in the Module $1$ discussion. For example, you might

focus on the process you used for each, the difficulties encountered, etc.
