caesar cipher the caesar cipher is an ancient encryption algorithm used by julius caesar it encrypts letters by shifting them over by certain number of places in the alphabet we call the length of shift the key for exampleif the key is then becomes db becomes ec becomes fand so on to decrypt the messageyou must shift the encrypted letters in the opposite direction this program lets the user encrypt and decrypt messages according to this algorithm in modern timesthe caesar cipher isn' very sophisticatedbut that makes it ideal for beginners the program in project "caesar hacker,can brute-force through all possible keys to decrypt messageseven if you don' know the original key alsoif you encrypt the message with the key the caesar cipher becomes identical to project "rot cipher
