Create a Certificate Signing Request (CSR)
A Certificate Signing Request (CSR) is a request sent to a Certificate Authority (CA) to authenticate the
credentials contained within the certificate.
We recommend installing a Root Certificate from the CA on your computer before creating the CSR.
1. Start your web browser.
2. Type "https://machine's IP address" in your browser's address bar (where "machine's IP address" is the
machine's IP address).
For example:
https://192.168.1.2
• If you are using a Domain Name System or enable a NetBIOS name, you can type another name, such
as "SharedPrinter" instead of the IP address.
- For example:
https://SharedPrinter
If you enable a NetBIOS name, you can also use the node name.
- For example:
https://brnxxxxxxxxxxxx
The NetBIOS name can be found in the Network Configuration Report.
3. If required, type the password in the Login field, and then click Login.
The default password to manage this machine's settings is located on the back of the machine and marked
"Pwd".
4. Go to the navigation menu, and then click Network > Security > Certificate.
Start from , if the navigation menu is not shown on the left side of the screen.
5. Click Create CSR.
6. Type a Common Name (required) and add other information about your Organization (optional).
• Your company details are required so that a CA can confirm your identity and verify it to the outside
world.
• The length of the Common Name must be less than 64 bytes. Enter an identifier, such as an IP
address, node name, or domain name to use when accessing this printer through SSL/TLS
communication. The node name is displayed by default. The Common Name is required.
• A warning will appear if you type a different name in the URL than the Common Name that was used for
the certificate.
• The length of the Organization, the Organization Unit, the City/Locality and the State/Province must
be less than 64 bytes.
• The Country/Region should be a two character ISO 3166 country code.
• If you are configuring an X.509v3 certificate extension, select the Configure extended partition check
box, and then select Auto (Register IPv4) or Manual.
7. Select your setting from the Public Key Algorithm drop-down list. The default setting is RSA(2048bit).
8. Select your setting from the Digest Algorithm drop-down list. The default setting is SHA256.
9. Click Submit.
The CSR appears on your screen. Save the CSR as a file or copy and paste it into an online CSR form
offered by a Certificate Authority.
