Viewing Certificate Details

This section provides a tutorial example on how to view certificate details when visiting an 'https' Web site in Chrome 24.

When you visit a "https" Web server, it will send its certificate to your browser. Server's certificate is needed by the browser for these 2 tasks:

Normally, your browser will do these 2 tasks automatically without your interaction. You don't need to know where is the server certificate and what's in the certificate.

But since I am interested to learn more about "https" communication, I want to see the server certificate. Here is what did on Chrome 24 to see details of the server certificate.

1. Run Chrome 24 and go to and wait for the log in page to be loaded.

2. Click the lock icon at the end of the Web address field. A small pop up windows shows up.

3. Click the "Connection" tab and then the "Certificate information" link on the pop up window. The Certificate dialog box shows up. The General tab tells me this information:

This certificate is intended for the following purpose(s):
- Proves your identity to a remote computer
- Ensures the identify of a remote computer

Issued to:
Issued by: DigiCert High Assurance CA-3
Valid from 3/ 9/ 2012 to 3/ 14/ 2014

4. If you click the Details tab, you will details of this certificate:

Version               V3
Serial number         0c 07 04 ...
Signature algorithm   sha1RSA
Signature has algorithm sha1

                      Client Authentication (
Key Usage             Digital Signature, Key Encipherment (a0)
Thumbprint algorithm  sha1

Cool. Now I see details of a real certificate for commercial uses. The picture below shows you steps to reach certificate details:

Notice that the "Certificate" dialog box used in Chrome is identical to "Certificate" dialog gox used in IE (Internet Explorer) 9. See IE 9 tutorials for information provided on the "Certificate Path" tab.
