I just wanted to get a look at the super advanced crypto that goes into 83850c but apparently Geremia is not sharing source code for FreeKey… so one thing led to another and i ended up writing this little app while deciphering the (actually quite disappointing) algorithm. Enjoy!

This is mainly provided for curious people and I can NOT guarantee that the keys it gives you are correct (but it seems to work properly). Please don’t ask me for help with this application unless you are working on integrating this functionality into JungleFlasher(info)(info)
