Basiclly if you type a long string it will half the size of it. Very useful for game save codes, etc. How it works: So it has a list, filled with all combinations of all leters in the length of 2. Then it has another list with a bunge of "strange" symbols in that it use to convert it. It simply only works with whole words, but I easily overcame this by just adding a space to the input.
All made by me
