Answer: Compared to a Caesar shift, the random substitution cipher offers many more possibilities, because the encryption is randomly chosen.

A Caesar Cipher is also a type of substitution cipher, but instead of doing it randomly, it shifts the alphabet by a certain number of characters. Therefore, the answer to decrypt the message is simply to figure out that number.
