Viewing Certificate Details
This section provides a tutorial example on how to view certificate details when visiting an 'https' Web site in Firefox 18.
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:
- Your browser must validate the certificate to determine that the Web site can be trusted or not before doing any further communications.
- Your browser must use the public key in the certificate to help secure the communication messages sent and received.
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 Firefox 18 to see details of the server certificate.
1. Run Firefox 18 and go to https://login.yahoo.com and wait for the log in page to be loaded.
2. Click the lock icon in front of the Web address.
The Page Info dialog box shows up with the Security tab selected.
3. Click the "View Certificate" button. The Certificate Viewer dialog box shows up.
The General tab tells me this information:
This certificate has been verified for the following uses:
SSL Server Certificate
Common Name (CN) login.yahoo.com
Organization (O) Yahoo! Inc.
Common Name (CN) DigiCert Assurance CA-3
Organization (O) DigiCert Inc
Issued On 1/9/2012
Expires On 3/14/2014
SHA1 Fingerprint 68:22:...
MD5 Fingerprint 94:28:...
4. If you click the Details tab, you will see more information about this certificate.
See the picture below:
Cool. Now I see details of a real certificate for commercial uses.
While on the Details tab of the Certificate Viewer, you can also:
- Look at each certificate of the Certificate Hierarchy.
- Export any certificate in the Certificate Hierarchy to a certificate file.
- Installing certificates into the browser is not supported.
