makes letters shift left or right on the alphabet, left if in an even place, right if in an odd place. e.g. "aa" becomes "zb" drag the sliders to change the amount it shifts to decode, use negative numbers if encoded in positive numbers and positive numbers if encoded in negative numbers.
it is broken oops makes letters capital, any character that isn't a letter may become a letter (including spaces) if it says something bad it not my fault recommended that you use 1-1 if in an ARG or hidden lore having one positive and one negative is a caesar cipher I think
