The Caesar cipher is an ancient encryption algorithm used by Julius Caesar. It encrypts letters by shifting them over by a certain number of places in the alphabet. We call the length of shift the key. For example, if the key is 3, then A becomes D, B becomes E, C becomes F, and so on. To decrypt the message, you must shift the encrypted letters in the opposite direction. This program lets the user encrypt and decrypt messages according to this algorithm.
In modern times, the Caesar cipher isn’t very sophisticated, but that makes it ideal for beginners. The program in Project 7, “Caesar Hacker,” can brute-force through all ...
