Dsi common key found!
The DSi's common key is an unknown encryption key (using the AES-CBC-128 algorithm). It is used to decrypt the title key in a ticket.

Loopy had substantially claimed to have found the common key, somewhere around 2009, but he didn't share it. He did, however, provide a small partially misleading amount of information on it. (There are no 00 bytes and the first bit is a 1.)
The common key can together with [http://wiibrew.org/wiki/NUS_Downloader NUSD] be used to decrypt dsi-wares (and everything that runs on the dsi for that matter, such as the dsi camera app, system settings etc.)
The common key is *not* in the RAM while either of the currently exploited games are running. The common key is not the same as (and not to be confused with) the Wii's.

Apparently, someone registered the common key as a .com domain the 16 of september 2009 with the following text:
"GTFO NAO, U CANNOT HAZ SITEZ.
DSI COMMON KEY HAS WAN USE. SIGNIN HOMEBREW 2 RUN ON DSI IZ NOT WAN OV THEM. NINTENDO DOESNT EPIC FAIL LIEK SONY IN DIS REGARD.
BTW, OH HAI THAR NINTENDO"
The Common key can be extracted from this program (for legal reasons):
