Outdated: Visiting "https" Web Site with Chrome 24
This section describes how Google Chrome 24 shows a lock icon when you visit an 'https' Web site to provide you more security related information.
Google Chrome is becoming a 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 24, 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 use Chrome 24 to visit the Facebook log in page: "https://www.facebook.com":
If you click the lock icon, then the "Connection" tab, Chrome will provide you a summary of security related information about this Web site. For https://www.facebook.com Web site, you will get something like:
www.facebook.com Identity verified The identify of this website has been verified by VeriSign Trust Network. "Certificate information" link Your connection to www.facebook.com is encrypted with 128-bit encryption. The connection is encrypted using RC4_128 with SHA1 for message authentication and RSA as the key exchange mechanism. The connection does now use SSL compression
More security related information will be provided if you click the "Certificate information" link. See next sections.
