FYI, what looks like a section header icon followed by the text "So what's the habibi key?" is actually a clickable expanding segment (html details). You should click it if you're interested!
A question I have is where/when/how the corresponding private habibi key was released/leaked, if the story about it being used exclusively by the linux console group to prevent pirated content from being used is true. OP clearly was able to patch the four byte difference between the MS key and the habibi key to then run "unsigned" (but, actually, signed with the habibi private key) executables, so they clearly got their hands on it.
- bri3d 2y agoThe Habibi key is generated by patching the Microsoft key to be divisible by 3, making it quite easy to factor indeed. The private key can be trivially recovered from the public key, and there was nothing really to release or leak. It was basically a little crypto CTF buried in the original 007: Agent Under Fire savegame hack, which was basically a CTF in and of itself (it was reasonably heavily obfuscated, I think both as a middle finger to pirates and as a challenge to other reverse engineers).
- ComputerGuru 2y agoThanks, that makes perfect sense.
