I'm attempting to write an extension which verifies the SHA1 fingerprint of a site's SSL certificate with a third party. However it doesn't seem to be possible to do this either through native JavaScript or Chrome's extension APIs.
I found this question which would seem to do what I want: How can I get the SSL Certificate info for the *current* page in a Firefox Extension
But unfortunately it is only applicable to Firefox. Is there any way to do this in a cross browser compatible way, or even just in Chrome?
