This is mainly as a homework help (we are studying caesar codes at school and this is to help crack one) but I have uploaded it anyway. The Decoder is used by typing in the code and it will turn it into 25 different forms of plaintext. You then just have to select which one is the right one (which makes sense) and then add in the spaces and you will have the correct plaintext. Works best with turbo speed or in flash player. Delete all spaces from the code before inputting.
