totally silly. they also implemented the test of user presence (TUP). there's little point to a software version of a U2F token if user-interaction is still required.

I think this is what krypt.co does, and they have an extension for Firefox (I use it daily). It's pretty neat.

The crux of this post looks to be "this is how I built a thing," which is also pretty neat.

I'd love there to be some sort of "adapter" extension for smartcards so they can be used with webauth. Would let us reuse our already existing smartcard infrastructure.

I'm sure I could build one if you want. I maintain some smartcard middleware that works in Chrome (as a certificate provider, and on Windows, macOS, Linux, Solaris, HP-UX, etc) called CACKey: https://chrome.google.com/webstore/detail/cackey/lpimdiknnpi... (or https://CACKey.rkeene.org/ )

I recently added SSH agent support to this as well.

Email me I'm interested in your situation, cackey@rkeene.org

But using more than 100% of his memory kind of takes away from it. I guess those defunct processes could be swapped to disk, but who keeps more than twice their RAM in swap space...

Thanks! I'm not very good at designing so kept it "simple".
