Librem 5 PGP verification through cryptsetup

[FranklyFlawless]

I recall @Kyle_Rankin discussing about this concept years ago, although I believe it was only successfully implemented for PureOS on the desktop.

Librem Key with QubesOS

Qubes doesn’t support OpenPGP smart card unlocking in LUKS. Debian and PureOS do, because of plugins the Debian team has made for their cryptsetup packages. Someone would have to port Debian’s cryptsetup approach to supporting OpenPGP smart cards for unlocking, to how Fedora (which Qubes uses for dom0) handles LUKS.
