In this project, you will write C++ programs to decipher secret messages! The secret messages were created by encrypting the original message with a cipher. A cipher takes the original message, and a secret key, and produces an encrypted message. Normally, the secret key is required for decryption, i.e. to get the original message back from the encrypted version. Hence the encrypted message is supposed to be safe, in the sense that only people with knowledge of the secret key can reconstruct the original message. However, your task will be to break the cipher. That is, figure out the message, without the secret key!
