Well, if you are reducing a specific range (i.e. 256-511) by modding by 255, then yes you can get back to the number by adding the starting range value to the mod value. However, if your range exceeds 255 then you would lose the ability to reconstruct the value.
the length is dependant on the key and message (in a text file) length. Can anyone shed some light on how to encrypt these int arrays to ASCII values and then decrypt back to standard?
