    Hello,
    Thank you for posting in our TechNet forum.

    After my research, the TRUSTED CERTIFICATE variant is an OpenSSL-specific format which includes "trust rules" appended to the certificate. This is used by the OpenSSL trust engine to determine if the presented end-entity certificate is valid for its current usage.

    For more information, we can refer to the following link.
    https://www.openssl.org/docs/man1.0.2/man1/x509.html

    And in my lab (Windows), after I generate a csr file, I can see it begins with "-----BEGIN NEW CERTIFICATE REQUEST-----".
