OK, I think I should have time tomorrow to attempt to start writing a little demo web app that will use a nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl to log in.

Technically, it will support any software that can export an xpub and then sign an arbitrary message with an associated key, but my test case is the #SeedSigner.

The idea is not limited to just logging into a website, of course. However, for simplicity, my demo will be limited to just that.

My hope is that I'll be feeling well enough to grind through to the point where if you scan the QR code with a phone and then enter the string (for xpub and signature), you'll be able to demonstrate the capability. Adding in JS code to scan a QR code will probably be saved for another day's work.
