Is there any way to access certificate information from a Chrome Extension

I'd like to access SSL certificate information from a Google Chrome extension.

I took a look at the APIs here: http://code.google.com/chrome/extensions/api_index.html, but didn't see anything that would get the job done.

Ideally I'd like to get access to Issuer, Validity Period, Subject, Serial Number, etc...

This seems to be possible in Mozilla/Firefox:
