RC4 and Base 64 Coder
This small utility allows the conversion from an encoded string to a decoded string and vise versa. It can do this for the Base 64 and RC4 algorthims. RC4 requires a key as it is a method of encryption, an input is provided for this with a default key. The key should be between 0 and 255 characters, as 255 is the maximium the code will deal with.
