Enrollment via an RA If you select Create a certification request and enroll for a certificate
immediately online , you can select this option to apply for a certificate
through a RA (Registration Authority). The RA is an intermediary authorized by
a CA to verify each subscriber’s identity and forward the requests to the CA.
After the CA signs and issues the certificates, the RA distributes the
certificates to the subscribers.
