Type in what message you want to encode. Click the flag to encode another message. Decode: a=b; each letter decodes into the letter that is in front of it in the alphabet. (Z would be A) You can use a cipher wheel to decode the message. Line up the outer letter A with the inner letter B. (or line up Z with A).
Hooray! It now supports every keyboard character! Horray! I've added a decode mode! If the screen is blank after you click the green flag, click the flag again.
