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.

Generate a key and certificate using Remote UI from a computer. You cannot use the operation panel to generate a key and certificate. Administrator privileges are required.

  1. Log in to the Remote UI in Administrator Mode.

  2. On the Portal page of Remote UI, click Settings/Registration.

  3. Click Device Management > Key and Certificate Settings > Generate Key.

    The Generate Key screen is displayed.

  4. Select Network Communication, and click OK.

    The Generate Network Communication Key screen is displayed.

  5. 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.

  6. In Certificate Settings, set the certificate information.

    Validity Start Date (YYYY/MM/DD) / Validity End Date (YYYY/MM/DD)
    Enter the start and end dates of the certificate validity period.
    Country/Region
    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.
    State / City / Organization / Organization Unit
    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).

  7. Click OK.

  8. Logout from Remote UI.
