Visiting an "https" Web Site with Chrome
This section describes how Google Chrome shows a lock icon when you visit an 'https' Web site to provide you more security related information.
Google Chrome is becoming the most popular Web browser now. Let's take a quick look at how Chrome uses public key certificates.
If you go to a Web site that provides online services, I am sure that you will see "https" in the Web address field starting on the log in page. This indicates that Web site uses SSL protocol to encrypt all information you send and receive on this server.
If you are using Google Chrome version 75, it will display an extra lock icon in front of the Web address field when you are connecting to an "https" Web site. The picture below shows the "https" Web address and the lock icon when you visit the Facebook log in page at https://www.facebook.com.
If you click the lock icon, Chrome will provide you a summary of security related information about this Web site:
Connection is secure Your connection (for example, passwords or credit card numbers) is private when it is sent to this site. Certificate (Valid)
More security related information will be provided if you click the "Certificate" link. See next sections.
