Well, not even guess, lmfao. With enough keys from games, THEN that could likely be figured out. I imagine the more keys appear/are tracked that the closer this will be to reality;-) Fun day so far, great news. Wonder what F0F response will be to the "Call out" by who released this dump and the aes key? Checked earlier this morning but saw nothing.the magic behind encryption is you generate a unique value per encrypted content, another unique key won't do anything if the encrypted content has other closely, specified and tied data [the key comes from this]
but if you guess the formula, like how the PS3 was hacked years ago, you can sign your own data, and decrypt them too.
EDIT: another question; what did this group use to dump the game, ONLY the WiikeyU? Also wondering how they explored file system and how they extracted the key; interesting things to know for obvious reasons.
