How to View Subject Alternate Names in Google Chrome

Google Chrome is one of the most popular web browsers, known for its speed, security, and user-friendly interface. It offers various features and settings that can enhance your browsing experience. One of these features is the ability to view Subject Alternate Names (SANs) in the browser. SANs are used in SSL certificates to secure websites and ensure their authenticity.

If you want to check the SANs of a website in Google Chrome, follow the step-by-step guide below:

Step 1: Open Google Chrome

Launch Google Chrome by double-clicking on its icon on your desktop or by searching for it in the Start menu.

Step 2: Visit the Website

Enter the URL of the website whose SANs you want to view in the address bar at the top of the Chrome window. Press Enter or click the arrow button to load the website.

Step 3: Open Developer Tools

To access the Developer Tools in Google Chrome, you have two options:

• Right-click on any part of the webpage and select "Inspect" from the context menu.
• Press the Ctrl + Shift + I keys simultaneously on your keyboard.

Step 4: Switch to the Security Tab

Once the Developer Tools panel opens, you'll see multiple tabs at the top. Click on the "Security" tab to switch to it.

Step 5: View the Subject Alternate Names

In the Security tab, you'll find detailed information about the website's SSL certificate. Look for the "Subject Alternative Name" field, which lists all the SANs associated with the website. The SANs can be domain names, IP addresses, or even email addresses.

If you don't see the "Subject Alternative Name" field, it means the website's SSL certificate doesn't have any SANs.

That's it! You have successfully viewed the Subject Alternate Names in Google Chrome.

It's important to note that viewing the SANs of a website can be useful in various situations. For example, it can help you verify if a website is using a valid SSL certificate or if it's a phishing attempt. Additionally, if you're a website owner, checking the SANs can ensure that all the necessary domains and subdomains are included in the SSL certificate.

Remember to always be cautious when entering personal information or conducting financial transactions on websites. Checking the SANs is just one step in ensuring the security of your online activities.
