Create a Certificate Signing Request for NetScreen ScreenOS

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. You will have to request a new SSL Certificate and may be charged.

The CSR needs to contain the following attributes:

Common Name – Must match the URL you plan to secure exactly – is usually your fully-qualified domain name (e.g. devel.ssl247.ie or mail.devel.ssl247.ie). Remember the www. is important – include it if you want to secure https://www.yoursite.com & exclude it if you want to secure https://yoursite.com.
Organisation - The legal (officially registered) name of your organization/company include Inc., LLP., Pvt, Plc. Ltd. SARL., etc.
Organisational unit - The name of your department within the organization (this is often "IT," "Web," or is just left blank).
City/locality - The city or town in which your organization is located.
State/province - The state in which your organization is located.
Country - Click here for the official list of ISO country codes for this field.

Note: Certificates can only be used on Web servers using the Common Name specified during enrollment. For example, a certificate for the domain "domain.com" will receive a warning if accessing a site named "www.domain.com" or "secure.domain.com", because "www.domain.com" and "secure.domain.com" are different from "domain.com".

We recommend that you contact the ScreenOS vendor for additional information.
