Generate a CSR code on FortiGate

CSR stands for Certificate Signing Request, a block of encoded text with your contact details inside. The Certificate Authorities use the CSR code to verify your credentials before they can approve your SSL request.

Along with the CSR code, you will also create your Private Key. The CSR and Private Key form the SSL certificate key pair. To generate the CSR code on FortiGate, you have two options:

  1. Generate the CSR automatically using our CSR Generator.
  2. Follow our step-by-step tutorial on how to create the CSR on FortiGate.

Install an SSL Certificate on FortiGate

After your CA sends your signed SSL Certificate, download the ZIP folder and extract the contents on your device. If you’ve generated the CSR code on FortiGate, your Private Key is already on the FortiGate server.

Please, follow the steps below to install your SSL certificate:

  1. Open your primary and intermediate certificates
  2. Copy and paste their contents into separate Notepad files and save them with .crt extension. Copy the encrypted certificate text, with the —–BEGIN CERTIFICATE—– and —–END CERTIFICATE—– tags.
  3. Log into your FortiGate control panel
  4. Navigate to System > Certificates and select Import > Local Certificate
  5. Browse your primary certificate and click OK. The status of your certificate should change from PENDING to OK
  6. Next, import your intermediate certificate. Go to System > Certificates and select Import > CA Certificate
  7. Browse your intermediate certificate and click OK. You should see your intermediate CA in the CA Certificates list
  8. Now, click on VPN > SSL > Settings
  9. In the Connection Settings pane, under the Server Certificate drop-down menu, select the SSL certificate you’ve just installed and click Apply.

Congratulations, you’ve successfully installed an SSL certificate on the FortiGate VPN system.
