Certificate Signing Request (CSR) Generation Instructions for Netscreen ScreenOS


This document provides installation instructions for Netscreen. If you are unable to use these instructions for your server, Symantec recommends that you contact the server vendor or the organization, which supports ScreenOS.

NOTE: To generate a CSR, you will need to create a key pair for your server. These two items are a digital certificate key pair and cannot be separated. If you lose your public/private key file or your password and generate a new one, your SSL Certificate will no longer match.

To generate a Key Pair and CSR, perform the steps bellow:

NOTE: All certificates that will expire after October, 2013 must have a 2048 bit key size.

  1. Open the WebUI
  2. From the Options menu, click Configuration, and then Date/Time.
    NOTE: If the Options menu is not available, look for the Configuration option
  3. From the Date/Time page, click Sync Click with Client. Ensure that Automatically adjust clock for daylight savings changes is selected.
  4. From the options menu, click Network and then click DNS.
  5. Enter the Hostname of the device is the Hostname textbox, and then enter the Domain name of the device is the Domain name textbox. This two together will become the Common Name.
  6. From the options menu, click Objects, click Certificates, and then click New.
  7. Fill out all of the necessary fields:
    • Country Name (C): Use the two-letter code without punctuation for country, for example: US or CA.
    • State or Province (S): Spell out the state completely; do not abbreviate the state or province name, for example: California.
    • Locality or City (L): The Locality field is the city or town name, for example: Berkeley.
    • Organization (O): If your company or department has an &, @, or any other symbol using the shift key in its name, you must spell out the symbol or omit it to enroll. 
    • Organizational Unit (OU): This field is the name of the department or organization unit making the request.
    • Common Name (CN): The Common Name is the Host + Domain Name. It looks like "" or "".
      NOTE: Symantec certificates can only be used on Web servers using the Common Name specified during enrollment. For example, a certificate for the domain "" will receive a warning if accessing a site named "" or "", because "" and "" are different from "".
  8. Click Generate.
  9. You have just created a key pair and a CSR.
  10. Verify your CSR
  11. Copy and paste the CSR into the enrollment form when required

Once the SSL certificate has been issued, follow the steps from this link to install it on the server: INFO125
