Install custom CAcert under /system/etc/security/cacerts/

Hello all,

Android 13 mit e/OS 3.0.1, Fairphone 5

I’ve had my own CA for a long time. It works very well. I can also install the custom CA in the system settings. Unfortunately, however, many apps do not access the user certificate store.

So I had the idea of storing the CA directly under “/system/etc/security/cacerts/”. But normal users don’t have access to this directory. It doesn’t work with adb either.
Is it possible to temporarily grant access to the directory in developer mode, store the CA, and then remove the permissions again?

Thanks :slight_smile:
