Viewing Certificate Details

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

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 IE to see details of the server certificate.

1. Run IE 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. The General tab tells me this information:

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

Issued to: *.login.yahoo.com
Issued by: DigiCert SHA2 High Assurance Server CA
Valid from 8/18/2019 to 2/15/2020

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

This certificate has been verified for the following uses:
 SSL Client Certificate
 SSL Server Certificate

Issued to
Common Name (CN)   *.login.yahoo.com
Organization (O)   Oath Inc.

Validity

Cool. Now I see details of a real certificate for commercial uses.
