Common key

The DSi's common key is an unknown encryption key (using the AES(Rij)-CBC-128 algorithm). The following appear to be encrypted with the common key (if not a different key):

-Firmware

-NOR

-"Channels" from the DSi Shop

-Possibly others, details are fuzzy

Only Loopy has substantially claimed to have found the common key, but he has not shared it. He has, however, provided a small amount of information on it. (There are no 00 bytes and the first bit is a 1.)

The common key is *not* in the RAM while either of the currently exploited games are running.
