even if cloud computing to find the key, it is still too long to brute force. the best way is we need some super smart math guy.
we know that the newer eboots are encrypted with the same key.
we also could get unencrypted eboots from the ram.
so we need some super smart math guy to come out with a method to narrow down the calculation based on the eboots we have.
the formula should be the same so we are just missing the key but we got the start and end so if someone reorder the formula we might get the key that is the middle.
