No method to check thumbprint of certificate received from website

Reported by, Dec 6 2010

Issue description

Chrome Version       : <Copy from: 'about:version'>
URLs (if applicable) : 9.0.587.0 (Official Build 66374) dev
Other browsers tested: Firefox
Add OK or FAIL after other browsers where you have tested this issue:
  Firefox 3.x: OK

There is no way to access the SSL certificate information received from a website. This makes it impossible to create a simple extension that stores certificate thumbprints to notify on changes. 

Firefox allows extensions to call it with code similar to the following.
var ui = gBrowser.securityUI;
sp = ui.QueryInterface(Components.interfaces.nsISSLStatusProvider);
status = sp.SSLStatus;
status = status.QueryInterface(Components.interfaces.nsISSLStatus);
var cert = status.serverCert;

There is no security reason to not have access to the public certificate that can easily be caught in a packet capture.

Is this something that makes sense to expose through the web request API?

Comment 4 by, Dec 10 2010

Yes, security state information like this should be public because its stuff that is already available in plaintext to any observer of the TLS handshake. 
Of course the private key shouldn't be exposed, but the public key is available to anyone that connects to the server. There isn't any reason to keep it from the end user.

This will allow extensions to monitor signing authorities for users in countries that pressure CA's into creating signing certificates for eavesdropping purposes.

Is there any change on this issue? I really need the server certificate in my extension.
