and maybe some sort of physical way to share keys via qr or something with clear transparent state visualization. the more you abstract away the cryptography math the less safe it feels with more vectors of attack so it has to be also educational like "this is how proper cryptography works and here is proof we are doing everything by the books" but in friendly ux manner thats easy for children to grasp intuitively
