Feature Request: Diffie-Hellman Key Exchange about flutter_string_encryption HOT 2 OPEN

Diffie-Hellman is a start, but built on it is Station-to-Station protcol which uses digital signatures in order to prevent man-in-the-middle attacks. Just a suggestion ;)

@RobbertH That's a cool protocol! There are a few times I've used DH that I probably could/should have used that instead.

In my case (IoT device) that would be a place where I would have to personalize the firmware for each device, whereas with pure DH I can re-use the same binary image. (I'm trying to avoid that personalization step, I'd probably use full-on PKI if I did). In my setup, physical security is required to push a reset button, which activates time-limited Bluetooth hardware only for the DH exchange, but in my nightmares I think about all the ways that MITM could still happen.
