I believe the SSL Certificate Checker tool is available for usage. See https://www.ssl2buy.com/wiki/ssl-installation-checker for more information. By using this link, you can find out the name of the SSL certificate authority that is currently installed on your client's computer.

If not, you can verify the certificate details using the OpenSSL command-line tool's alternative option. Here is an example command to view a certificate's details:

-in certificate.crt -text -noout openssl x509

The certificate's details, including the signing authority, expiration date, and more, will be shown by using this command.

I hope that this aids in your search for the data you need.

To determine the name of the Certificate Authority (CA) of an existing SSL certificate from a client machine, you can inspect the certificate details using several methods. One of the easiest ways is through a web browser such as Chrome or Firefox. When you visit the secured website, click on the padlock icon in the address bar, then view the certificate details. The "Issued by" section in the certificate window will show the name of the CA, such as Trustwave, Comodo, Symantec, or GeoTrust.

Alternatively, from the command line, you can use openssl to retrieve certificate information. Run the command openssl s_client -connect example.com:443 -showcerts, and examine the output for the "issuer" field, which indicates the issuing authority. On Windows, PowerShell can also be used with a command like openssl s_client -connect example.com:443 | openssl x509 -noout -issuer to display the issuer directly. These methods will help you identify the certificate authority regardless of whether the certificate was issued by Trustwave, Comodo, Symantec, GeoTrust, or another provider.
