Juniper Netscreen ScreenOS

Preparing the NetScreen

Before creating the CSR and private key on Juniper NetScreen machines, you must first synchronize the clock. To do this, connect to the Netscreen's web interface. Select "Options", then "Configuration", and then "Date/Time".

Click the "Sync Clock with Client" button. Set the "Automatically adjust clock for daylight savings changes" option and click "Yes". Back in the "Options" menu, click "Network" and then "DNS". For "Host Name", enter the device's host name. For the "Domain Name" field, type the fully qualified domain name, such as or, not the internal name. Click "Apply".

Entering the CSR Data

Go back to the "Options" menu, click "Objects" and then click "Certificates". Click "New" and complete the fields about your company. While you complete these fields, we ask that you keep a few things in mind:

Certificate Information Guidelines

Location - Enter the location where your business operates, not where your server is located. If you are an international customer in a country without a State/Province or City/Locality, leave those fields blank.

  • Country Name - Enter the two letter International Organization for Standardization (ISO) abbreviation of the country where your organization is legally located.
  • State/Province - Spell out the entire name of your state or province. For example, if your business operates in Texas, enter "Texas" and not "TX".
  • City/Locality - Spell out the entire name of your city or locality.

Organization - Enter the full, unabbreviated legal name of your business. Include any applicable suffix, such as "Inc" or "LLC". If your company name is registered in an abbreviated form, then you may use that abbreviation if you want.

Organizational Unit - This field will not be included in your certificate, so you can leave it blank.

Common Name - Enter the web address of your site. It must be a fully qualified domain name. Both and are acceptable. Do not include http:// or https://. When ordering a wildcard SSL Certificate, you will use *

Email Address - Enter the address of the person responsible for SSL in your organization. This field is optional.

When you are finished entering information, click "Generate" and save the CSR as a text file.

Protect your new private key for an SSL certificate

  1. Never give this file to anyone outside your company. Also restrict the access to it to the smallest possible group of employees.
  2. When you get your certificate, you must install this private key in a secure folder that has limited access to a root user and is protected with read-only permission.
  3. Backup your private key. There is no way to recover it if it is lost. Protect that backup with additional security such as an encrypted or password-protected backup. Your private key is integral to the SSL process.
  4. If you suspect that your private key is compromised, alert Trustwave® immediately. Trustwave® will revoke your certificate so that you can generate a new private key and CSR. You can then submit the new CSR for Trustwave® to reissue your certificate.

Submit the CSR to Trustwave®

Now navigate to the location of your saved CSR and open it with a suitable text editor such as Notepad, TextEdit, or vi. Copy the entire text - including the top and bottom dashed lines. You can paste this text directly into the Trustwave® Control Center - Submit your CSR to proceed to validation.
