I just tried out some of the live web crypto demos that I’ve blogged about on my Moto 360 AndroidWear watch. Most of them read files which doesn’t seem to work on a watch (go figure). But the one that creates and stores key pairs works fine! It’s a pretty terrible user experience given that the page isn’t even well designed for a phone, much less a watch, but it works.
Wow. Public key cryptography in a web browser on a wristwatch. This API is a game changer.
