Availability of certificates in the browser

There is a huge lack of support for client-side certificates in browsers. It seems [this will not change](https://lists.w3.org/Archives/Public/public-webappsec/2016Feb/0076.html). Some European countries on the other hand are strong in e-government, you can fill taxes online, you get state issues digital certificates which you can use to sign documents and signatures are equivalent to normal signatures. But the issue is that it is hard to really build around those digital certificates. You cannot make web applications which would use them.

So it would be great if keybase keychain would be available in the browser. So that apps could request it to sign documents.

I wanted to make a simple web applications where people could sign petitions using state-issues certificates, but it is not possible. Even if users have key pair imported into the browser.

Maybe keybase could address this ecosystem issue.

No files, tests, or entry points are identified. Start by reviewing the browser client-side certificate limitation and the proposed Keybase keychain integration described in the issue. Define a concrete integration path and acceptance criteria before implementation.
