CertViewer

Click the padlock icon to display SSL Certificate information of the current tab.Chrome doesn't have the ability to (easily) view the SSL Certificate and SSL information. It will either take 5 mouse clicks or 2 if you use Ctrl+Shift+i.

When you click the CertViewer Icon (padlock), it will display a popup that contains information about the site in your current tab.

How it works:
1) Go to an HTTPS website (https://<hostname.domain>)
2) Click the padlock icon in top right
3) Popup will show up and display the SSL connection and PKI certificate information of that site.

Caveats:
1) This makes an external connection to the site, so the site needs to be externally accessible and not have any access control policies.
2) You do send your active tab URL to my server when you click the padlock. I don't do anything with the URL except make connections using tools such as openssl and curl.
3) The site needs to have SSL enabled for this to work.
