Updating a Self-signed Certificate

If your product supports the HTTPS server feature, you can update a self-signed certificate using Web Config.
  1. Access Web Config and select the Network Security tab.
  2. Under one of the following network security options, select the corresponding certificate:
    • SSL/TLS and Certificate
    • S/MIME and Client Certificate (WF-C879R)
      Note: When you update a self-signed certificate for S/MIME, you cannot change the sender's email address on the Network > Email Server > Basic tab. You must change all signature settings to Do not add signature on the Network Security > S/MIME > Basic tab, and then delete the self-signed certificate for S/MIME.
  3. Under Self-signed Certificate, click Update. You see a window like this:


  4. Enter an identifier for your product from 1 to 128 characters long in the Common Name field.
    Note: You can add up to 5 IPv4 addresses, IPv6 addresses, host names, or FQDNs; separated by commas. The first value is assigned to the Common Name field, and the rest are added to the Alias field of the certificate subject. You cannot enter a space before or after a comma.
  5. Select a validity period for the certificate as the Certificate Validity (year) setting.
  6. Click Next. You see a completion message.
  7. Click OK.
  8. Click Confirm to verify the certificate information.
