This is an extremely lazy project, but can be used against people who think that simple letter-shift codes (aka the most basic ones in which all the letters of the alphabet are changed a certain number of letters toward the end or beginning of the alphabet) can actually be effective codes. Turn on Turbo Mode for faster processing of what you type. Do not press decode until after your message loads. This project can only process letters, so other symbols will result in a repeat letter. Also, things must be lowercase. Sorry, again, this is really lazy. Put in a suspected letter-shift code, and click decode until you get something resembling actual language. If you click through and end up with the same message eventually without having it turn into language, the code is probably not a simple letter-shift.
