By default the first certificate delivered for the use of HTTPS is a self-signed certificate.
To ensure a fully trusted authentication, you can request and import a certificate delivered by a Certification Authority (CA-signed certificate). In WebTools Express you can generate a certificate request and later import the CA-signed certificate that you have received from the Certification Authority.
When you use a certificate, the client station that submits the print can check the identity of the controller.
By default, Canon delivers a Canon self-signed certificate. This certificate provides encryption of the print data between the client and the controller. It can be easily used.
This self-signed certificate has not been signed by a Certification Authority, consequently the web browser will display a 'Certificate Error' message the first time you use the HTTPS protocol.
When your security policy recommends it, the administrator can request and import a certificate delivered by a Certification Authority (CA-signed certificate).
For more information on how to do this, see Generate a certificate request, and Import a CA-signed certificate: Check and import the root certificate.
