Please read https://news.ycombinator.com/item?id=30761693 and the other comments again. Librem 5 has incredibly poor hardware/firmware security and it isn't possible for us to work around that at a software level. It's missing the basic hardware and firmware security features that are required. It's also missing functionality beyond that required to run the full OS.

It has no such thing (there is no open source secure element available aside from OpenTitan, although Trezor is working on one too) and it isn't an alternative to a proper secure element used by apps via the standard AOSP hardware keystore API (StrongBox keystore) and integrated into the rest of the hardware/firmware/OS for verified boot, attestation, throttling disk encryption key derivation attempts, insider attack resistance (only allowing signed firmware updates after owner account authentication) and the other features that are provided.

And what little "security" features the Librem 5 has, they aren't even using. One of their engineers came at me with "we have RPMB!" (a poor excuse for anti-replay memory that is semi-standard these days, and vastly inferior to dedicated chips like Pixels and iPhones have). I asked what they use it for, and got crickets.
