Hello
My target is samsung S20
Its possible to extract key from SKM prov ? or its possible to decrypt SKM encrypted data with GCM ?
as i can see in libsecobj.so its use so_derive_key for key extraction with basic information.
Then use GCM to decrypt data.
Is there any way to decrypt GCM encrypted data by (TEES_UnwrapSecureObject) with SKM on rooted samsung ?
