I figured out what went into the first box, and got the second secret, but I accidentally pasted that straight into the box, and when submitted I found I was finished. So does someone want to explain why I didn't need to do any decoding for the second one, just paste it in? Looking at the system of the puzzle, It just doesn't follow for me.
