FE100 0.22 with updated keygrabber

June 10th, 2009

I’ve seen the below forum thread and thought it would be a nice addition to add an alternative to ecc key extraction in the FE100’s keygrabber tool.

Extracting the ECC Key without xyzzy

quoting bushing from there…

Having learned this, I added ecc key extraction from bootmii nand dump into the keygrabber tool (third button in the keygrabber to get the keys)

Enough crap, here is the new keygrabber & bugfixed FE100 : FE100 V0.22

ps: By the way, if you are reading this and you are a member of wiibrew forums : could you pm an admin there and notify them that “forgot my password” feature there doesn’t seem to work for quite a long time… That’s why I didn’t reply to the original topic mentioned at the top of the post.

Below key stuff is just for the first button (Get stuff from Interwebz) to work correctly…

Here are the shared keys (the first two actually) that are necessary to unpack a wii savefile.

SD key (ab01b9d8e1622b08afbad84dbfc2a55d)
SD IV (216712e6aa1f689f95c5a22324dc6a98)
MD5 blanker (0e65378199be4517ab06ec22451a5793)

More information about these and other keys can be found on hackmii,
here :

Only reason I included them here is because the previous version of keygrabber was leeching those keys from hackmii blog. Now it will leech them from here… The reason I didn’t bundle this stuff into the FE100 package is to folow the common practice…

FE100 0.2b – Save unpacker and packer bundled with key grabber

WiiCrazy (I.R.on) – 26/12/2008
Bundled with key grabber tool, you no longer need to manually create
the files needed by the program. Just run the FE100KeyGrabber tool,

Here how you will use the FE100KeyGrabber,

1. Click the ‘Get stuff from Interwebz’ button to obtain sd-key, sd-iv and md5-blanker
2. Get a savefile from your wii (no matter what) and click the ‘Get stuff from a savefile’ button
and point it to the savefile…

It will give you
Ng-id (your console’s id)
NG-mac (your console’s wifi adapter’s mac address)
Ng-sig (your console’s elliptical curve crypt. public key)

and finally,

3. Click the ‘Get stuff from xyzzy key dump’ button, there you should provide your keys.txt you
obtained from xyzzy tool by bushing… This step will extract the ecc key (NG-priv) out of
keys.txt and you will be complete…

After you got all these keys, click the ‘Make me happy!’ button and program will save the
keys/information into the respective files so you can use them with unpacking and packing
saves with FE100…
