Generating a Key and Certificate

Generate the key and certificate required for TLS-encrypted communication on the machine. A self-signed certificate is used for the self-generated key.
For the algorithm of the keys and certificates that can be generated with this machine, see the specifications of the self-generated key and self-signed certificate. Keys and Certificates
Generate a key and certificate using Remote UI from a computer. You cannot use the control panel to generate a key and certificate.
Administrator privileges are required.
Log in to Remote UI in System Manager Mode. Starting Remote UI
On the Portal page of Remote UI, click [Settings/Registration]. Portal Page of Remote UI
Click [Device Management] [Key and Certificate Settings] [Generate Key].
The [Generate Key] screen is displayed.
Select [Network Communication], and click [OK].
The [Generate Network Communication Key] screen is displayed.
In [Key Settings], enter the name of the key, and select the signature and key algorithm.
Enter the key name using single-byte alphanumeric characters.
For the key algorithm, select [RSA] or [ECDSA], and select the key length from the pulldown menu. The longer the key length, the better the security, but this slows down communication processing.

Enter the start and end dates of the certificate validity period.
Select [Select Country/Region], and then select the country or region from the pulldown menu, or select [Enter Internet Country Code], and enter the country code.

Enter the items as needed using single-byte alphanumeric characters.
[Common Name]
Enter the name of the certificate subject as needed using single-byte alphanumeric characters. This corresponds to the Common Name (CN).
Click [OK].
The generated key and certificate are added to [Registered Key and Certificate] on the [Key and Certificate Settings] screen.
