∟Viewing Server Certificate with Chrome on Android Phone

This section provides a tutorial example on how to view server certificate details when visiting an 'https' Website in Chrome on Android Phone.

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

Your browser must validate the certificate to determine that the Website 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 Chrome to see details of the server certificate.

1. Run Chrome on your Android phone and go to https://m.facebook.com and wait for the log in page to be displayed.

2. Tap the lock icon at the left side of the URL address area. The connection information is displayed.

3. Tap on "Details" link. Connection details are displayed.

4. Tap on "Certificate information" link. The Website server certificate is displayed.
