I don´t take any credit for this information, this is just a "Copy and Paste" from different post around here.
All the credit should go to the original posters.

5. Open up the "wiikeyset.reg" that came with the Trucha Signer in UltraEdit and find the section:

6. Open the key.bin file in UltraEdit and make sure you are in hex mode (Ctrl-H).
* key.bin (You need to find it and download it for yourself, can´t link to this file)

"common key"=hex:00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00
...with the contents from key.bin. For example, if key.bin contained AABBCCDDEEFFAABBCCDDEEFF11223344, you'd enter...
