What about implementing aes or similar in something like a stm32 arm? The micro is interfaced to a keyboard and a lcd text display. Then you can type your emails or chat messages, have them encrypted in the arm micro, and sent through usb to a non-trusted host pc(or whatever) for delivery.

I have sometimes fed by paranoia cells by imagining such a separate secure machine interconnected via a rather hard-to-hack link: Taylor UUCP. I guess that reveals my age, and the fact most of my ideas are, well... not always practical.
