For each cipher: 1. Suggest two different ways of attacking the cipher. Make sure to indicate 2. Explain which of the two ways you would choose to break the cipher and 3. Break the cipher and include the plaintext in your submission along with a which attack scenario applies. why. detailed explanation of how you get the plaintext
