CETK decryption fails on arm9loaderhax #26

Closed ghost closed 8 years ago

ghost commented 8 years ago

On my two 3DSes, CETK/firmware.bin (Depending on if I include the firmkey) decryption fails via A9LH. They work normally via any other entrypoint.

It lacks some key needed. From A9LH it would at least miss the keys inside NATIVE_FIRM ARM9 section including Process9 NCCH. So setup the keys you have before decryption or firmlaunch.

Mind telling me which keys are required?

@fox8091 From 3dbrew:AES_Registers.KeySlots, read the whole sheet. I must admit I don't know what the keys should be. However if you force the console to try encrypt a known-text with its Normal Key in Keyslots, and compare the output with what you can get from other entrypoints, the comparison would tell you which keyslots are different.

For everyone getting here, just like I state on the FAQ on GBATemp, get a firmkey.bin for your console from anywhere, plailect's guide, for example: https://github.com/Plailect/Guide/wiki/Part-5-%28arm9loaderhax-&-Cakes%29
