         | used images.

         | 2/5, guys, sorry. I came here for an epic adventure and was
         | disappointed.

           | Great presentation, but I'll be holding my breath for v2 that
           | actually generates audio of purring and hissing and meowing
           | cats.

       | Tip
       | 
       | For the best experience, try saying "meow" or "woof" out loud
       | while your encryption runs. It doesn't affect the algorithm at
       | all, but it does make you feel more connected to the process!

       | For those interested in steganography-based encryption
       | techniques, some well-known cryptology researchers designed a
       | system for formally transforming encrypted messages into the
       | (well-formed) contents of arbitrary protocols or communication
       | mediums. The technique is called format transforming encryption
       | [1], and it could be applicable here to help conceal the very
       | presence of encryption being used by one who knows the
       | stegonagraphic scheme.
