Project Description
Background
A shift cipher is a basic way to encrypt messages. Each letter of the alphabet is assigned to another letter of the alphabet based on a shift value.
For example, an encrypted message has a shift value of -2: AMBCFQ
When the message is decrypted, it reads: CODEHS
Your Task
You’ll create a program that encrypts and decrypts a user-entered message by using a shift value to reassign the letters. The full decrypted or encrypted message is then printed to the console. You’ll use C++ string methods in order to sort and shift characters to encode and decode your messages.
