Installing an SSL certificate directly in the browser?

Question

Nginx

I can't find a way to install an X.509 certificate with a private key in the form of a P12/PFX container (or other form) from the server (nginx/php) directly to the browser (at least under Windows IE/Chrome). Those. I didn’t download the file - I clicked it, installed it, but as in Webmoney Light or Startssl - I clicked on the button on the site - voila - the certificate in the browser.
Can anyone met with a similar one or have ideas in which direction to dig?

Answer 1

Heh, it's getting smarter. A public-private key pair is generated by the html5 keygen tag, after which, based on the public key sent to the server in SPKAC format and the certificate request, a CA-signed certificate is generated and transferred to the browser.

Just look through firebug or the developer tools to see what headers are sent when the certificate is returned (and do the same). I think this will solve the problem.
