This project is an extension of the Send a Secret Message CS First Unplugged activity (g.co/csfirst/unplugged). Use the left and right arrows to set your encryption key, then click the "Encrypt" or "Decrypt" buttons to enter a message and encrypt or decrypt it. To encrypt a message, the program looks for each of your letters on the outer ring and replaces them with the corresponding letter on the inner ring. When you decrypt a message, the program does the reverse process.
