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:
Overall procedure to prepare and generate the CA-signed certificate request
Step Description

The current certificate can be:
• the original Océ self-signed certificate embedded
• a CA-signed certificate (delivered by a Certification
Authority) you previously installed
See
Back up a certificate and a private key
on page 140.
A2- Generate the certificate request Make this step when you want to request and install a

cate request

quest a (CA-signed) certificate

cording to the remarks/corrections suggested by the CA
request feedback

icate you will receive.
