That applies to play integrity, and a lot of getting that working is juggling various signatures and keys.
The suggestion above which I replied to was instead about software-managed keys, something handed to the app which it then stores, where the google drm is polled to get that sacred piece of data. Since this is present in the software, it can be plainly read by the user on rooted devices, which hardware-based keys cannot.
Play integrity is hardware based, but the eu app is software based, merely polling googles hardware based stuff somewhere in the process.
I understand. In the context of digital sovereignty, even if the linked shitty implementation is discarded (as it should be), every correct implementation will require magic DRM-like chip. This chip will be made by a US or Asian manufacturer, as the EU has no manufacturing.
