You cannot directly obtain a root certificate from a website using Chrome. Root certificates are trusted authorities that verify the authenticity of websites. They are not issued by individual websites but by organizations like Let's Encrypt, DigiCert, or Sectigo.
However, you can view the root certificate used to verify the website's security certificate in Chrome:
- Open the website: Navigate to the website you want to inspect.
- Click the lock icon: In the address bar, click the lock icon to the left of the website's URL.
- Click "Certificate": In the pop-up window, click the "Certificate" button.
- View the certificate chain: Navigate through the "Certification Path" tab to see the chain of certificates, including the root certificate at the top.
Note: You cannot download the root certificate directly from this window.
If you need a specific root certificate, you can find them on the websites of Certificate Authorities (CAs) like Let's Encrypt or DigiCert. You can also download root certificates from the Mozilla Firefox website.
Example:
To view the root certificate used to verify the security of Google.com, follow these steps:
- Visit Google.com.
- Click the lock icon in the address bar.
- Click "Certificate."
- Navigate to the "Certification Path" tab.
- The topmost certificate in the list is the root certificate.
Remember: Root certificates are essential for secure browsing, and you should keep them updated on your device.
