Request and import a CA-signed certificate

Description of the overall procedure to request and import a CA-signed
certificate
Introduction
By default the first certificate delivered for the use of HTTPS is an Océ self-signed certificate.
To ensure a fully trustful authentication, you can request and import a certificate delivered by a
Certification Authority (CA-signed certificate).
Information about certificates
When you generate a CA-signed certificate request on a controller:
• A new private key is created: this key stays in the controller
• The certificate request containing the public key is created. Send it to the Certification
Authority.
The CA-signed certificate you will receive also contains the public key. This public key is linked
to the private key already stored in the controller.
In the controller, the private key and the public key must match to enable a secure HTTPS
protocol.
To request and then import a CA-signed certificate while you are still using HTTPS, follow these 2
procedures, step by step:
