Using Microsoft CA to Create a Certificate
4
When you are prompted for the x509 Common Name attribute information, type your fully-
qualified domain name (FQDN). Use other information as appropriate.
5
Follow the instructions from your certificate authority to send the CSR.
To create a temporary, self-signed certificate until the CA returns your signed certificate, type a the
command line:
openssl x509 -req -days 30 -in request.csr -key privkey.pem -out sscert.cert
This command creates a certificate inside your current directory that expires in 30 days.
You cannot use a self-signed certificate for VPN remote gateway authentication. We recommend that you
use certificates signed by a trusted third-party Certificate Authority.
Using Microsoft CA to Create a Certificate
Certification Authority is distributed with Windows Server 2003 as a component. If the Certification
Authority is not installed in the Administrative Tools folder of the Control Panel, follow the manufac-
turer’s instructions for installation.
When you use this procedure, you act as the certificate authority (CA) and digitally sign your own
request. For the final certificate to be useful, we recommend that you acquire other certificates that
connect your private CA to a widely trusted, third-party certificate authority. You can import these
additional certificates on the Firebox X Edge Certificates page.
