cipher

Primary Task Response:

Julius Caesar used one of the earliest known cipher systems to communicate with Cicero in Rome while he was conquering Europe.  Caesar knew that there was a very high risk of ambush or spies when sending messages; therefore, he developed a cryptographic system now known as the Caesar cipher.  Please provide a detailed response to the below to include specific details and examples.

• 1)What is the Caesar ROT3 Cipher?
• 2)How does it work?
• 3)Although the Caesar cipher is easy to use, it is easy to crack.  How would an attacker break a Caesar-style cipher?
