Verification Service by RA

A Registration Authority (RA) is an authority in a Public Key Infrastructure (PKI) network that verifies user requests for a digital certificate and tells the Certification Authority (CA) to issue it.

While the RA cannot create or issue a certificate (this is the sole responsibility of the CA), RA works as an intermediary for the CA to collect necessary information and to process the following tasks

• receive user or device certificate requests;
• validate users or devices;
• authenticate users or devices; and
• revoke credentials if the certificate is no longer valid.
The main purpose of an RA is to ensure that a user or device is allowed to request a digital certificate from a specific website or application. If the request is allowed, the RA forwards the certificate request to the CA, which completes the digital certificate request process.
