How to verify TLS certificate in browser?

To verify a TLS (Transport Layer Security) certificate in a browser, you can follow these steps:

1. Open the Website: Navigate to the website whose TLS certificate you want to verify.

2. Check the URL: Ensure that the URL starts with "https://" instead of "http://". The "s" indicates that the site is using SSL/TLS encryption.

3. View Certificate:

   • Chrome: Click on the padlock icon in the address bar, then click on "Certificate". This will open a window showing the details of the certificate.
   • Firefox: Click on the padlock icon in the address bar, then click on the right arrow and select "View Certificate".
   • Safari: Click on the padlock icon in the address bar, then click on "Show Certificate".

4. Inspect Certificate Details:

   • Look for the "Issuer" field to see which Certificate Authority (CA) issued the certificate.
   • Check the "Valid From" and "Valid To" dates to ensure the certificate is current.
   • Verify the "Subject" field to confirm that it matches the domain name of the website.

5. Trust Indicators: Most browsers will display a green padlock icon in the address bar if the certificate is trusted and valid. If there are issues, you might see a warning message.

Example:
If you visit https://www.example.com, you should see a padlock icon next to the URL. Clicking on this icon will allow you to view the certificate details, confirming that it is issued by a trusted CA and that it is valid.

For enhanced security and reliability, consider using cloud services that offer robust TLS certificate management. For instance, Tencent Cloud provides services like SSL Certificate Service, which simplifies the process of purchasing, deploying, and managing SSL/TLS certificates.
