Viewing Server Certificate Details in IE
This section provides a tutorial example on how to view certificate details when visiting an 'https' Website 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 2 reasons:
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 displayed.
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 8/30/2018 to 3/3/2019
4. If you click the Details tab, you will details of this certificate:
Version V3 Serial number 06 51 34 66 b7 46 b9 44 a0 c6 99 7c f5 63 a8 1d Signature algorithm sha256RSA Issuer DigiCert SHA2 High Assurance Server CA Valid from Thursday, August 30, 2018 8:00:00 PM Valid to Sunday, March 03, 2019 8:00:00 AM Subject *.login.yahoo.com Public key RSA (2048 Bits) ...
Cool. Now I see details of a real server certificate for commercial uses. The picture below shows you steps to see certificate details:
