Using TEESimulator without LSposed #57

[acolombier]

Hi, same question than https://github.com/beakthoven/TrickyStoreOSS/issues/57 - I am wondering if anyone has attempted to run TEESimulator without the Lsposed framework installed, but as natively build component instead?

I'd like to be able to include this in my own Android build (LineageOS) natively, without needing to also include LSposed for security/stability reason.

LSPosed is never needed, it is used to provide logs in case that users are not able / available to do it manually.

Thanks for the fast answer!
So looking at the diagram here, do you have any idea our a native integration of TEESimulator would look like?
Is there a way to partially replace the actual service that provides this service?

No. If your intention is to modify the OS directly, I suggest understanding the Java (Kotlin) layer of TEESimulator and modify the keystore daemon of you OS directly. You can simply modify the binder results there, without hooking the binder at all.
