I don't have time to really look at this at the moment (which is a shame because I love these sorts of puzzles). It looks as though it's pretty much a challenge in brute forcing though. I don't know anything about the algorithms used for the key generation but I'm assuming they're already very battle tested (though not infallible) and an amateur, like myself, isn't going to be able to find any sort of kink in the armour.
Maybe I'm going mad but it seems that Challenge 4 is one of the easier ones - there are only about 3000 keys to generate in that case. The final challenge is obviously leagues above that with 128,063,081,718,016 combinations (by my reckoning - I may have miscalculated).

Either way, great marketing hack :)
