This updated version of the Enigmuh Cipher Code Generator adds 12 new characters and a plug board that enhances the encryption. When you start the program, you will be asked to enter the three wheel codes that can be letters A-Z or numbers 0-9. Next, you will be asked if you want to encrypt or decrypt a message. Finally you will be asked to choose the plug board configuration. Choose a letter A-D for the first connection and a number 1-4 for the second. You can see a visual of this in the image below at center left. When the blue light in the upper right corner comes on, you may begin typing.
