RE: Client script access to server cert info

What you're looking for is called a "certificate parsing module". Do a
search on that term and/or add open source to the search depending on what
you're looking for. It will do everything you are asking and more.

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.
