How to view Website certificate chain with Google Chrome 103? I want to know which root certificate authority issued the Website certificate.

In most cases, root certificate authorities do not issue Website certificates directly. They usually issue certificates to intermediate authorities, who when issue certificates to Websites.

This sequence of issuing (or signing) certificates from a root certificate authority to a Website is called certificate chain.

In Google Chrome 103, the certificate chain information is displayed in the same dialog box as the Website certificate.

1. Run Google Chrome 103 and visit https://www.yahoo.com/. You see Yahoo Website displayed with a lock icon displayed next to the Website address.

2. Click the lock icon on the left of the Website address. You see the site properties dialog box displayed.

3. Click the "Connection is secure" link. You see security properties displayed.

4. Click the "Certificate is valid" link. You see the certificate chain displayed on top of the Website certificate.
