Question: 1. Use the Caesar cipher with key equal to 5 to encode (encript) the sentence I like math. 2. Use the Caear cipher with key

1. Use the Caesar cipher with key equal to 5 to encode (encript) the sentence "I like math". 2. Use the Caear cipher with key equal to 11 to decode (decript) the sentence " RCLGTEJ TD YZE L QZCNP " 3. The Caesar cipher key used to produced the encoded sentence "LIPPS ASVPH" is a value between 1 and 5. Determine the key value that gives a meaningful sentence and provide the sentence as well. 4. Use the Vigener cipher with key "Fabrizio" to encode the message "Fabrizio arrested Fabrizio." 5. What is the issue with the choice of key "Fabrizio" for encoding the sentence "Fabrizio arrested Fabrizio"? 6. The word "food" translates into the Italian word "cibo". What is the key in the Vigener cipher that will encode the word "food" into "cibo"?
