Problem 1: The Caesar cipher involves replacing each letter of the alphabet with the letter standing three places further down the alphabet. For example, the letter 'a' is mapped to the letter 'a'. a) Given the below plaintext from Avenger End Game Quote, what is its ciphertext based on Caesar cipher? NO AMOUNT OF MONEY EVER BOUGHT A SECOND OF TIME b) If it is known that a given ciphertext is following Caesar cipher but with a different shift, what is the easiest cryptanalysis solution to decrypt the message? (Explain this technique in 2-3 sentences.)
