WebApp Sec: RE: Client script access to server cert info

RE: Client script access to server cert info

To clarify, what I'm looking for is a way for script on a page to access
the server certificate information used during the SSL connection over
which the page was provided. I.e. if Alice requests a page from
bob.com, but the bob.com server returns a certificate that actually says
mallory.com, and Alice presses "OK" when prompted about the discrepancy,
it would be nice if there was a way to detect this using script that ran
in the browser. I'm trying to find out if anybody knows of any
browser/DOM/DHTML objects that contain a description (signing chain, CN,
fingerprint, whatever) of the actual server certificate information
presented during the SSL handshake.

Phil
