Viewing Certificate Path
This section provides a tutorial example on how to view certificate path when visiting an 'https' Web site in IE 9. The top certificate in a certificate path is the CA certificate, which is trusted automatically.
As we learned from previous chapters, in order to validate a certificate, a certificate path
must be established to link the certificate to a CA (Certificate Authority) certificate.
Here is what I did to find the certificate path for https://login.yahoo.com Web site.
1. Run IE 9 and go to https://login.yahoo.com 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 "View certificates" link on the pop up window. The Certificate dialog box shows up.
4. Click the "Certificate Path" tab. A certificate path with 4 certificates shows up:
GTE CyberTrust Global Root
|- DigiCert High Assurance EV Root CA
|- DigiCert High Assurance CA-3
5. Double click on "GTE CyberTrust Global Root". Another Certificate dialog box shows up providing
information on the GTE CyberTrust certificate, which is also the CA certificate,
because it is the top certificate in the certificate path.
This certificate is intended for the following purpose(s):
- Ensures the identify of a remote computer
Issued to: GTE CyberTrust Global Root
Issued by: GTE CyberTrust Global Root
Valid from 8/ 12/ 1998 to 8/ 13/ 2018
It is interesting to see that:
- This certificate is valid for 20 years! Can we trust this CA for that long time?
- The CA certificate is a self-signed certificate.
The picture below shows you the certificate path of login.yahoo.com:
