9.4 How to Use a Shared SSL Certificate
Websites that contain sensitive information or ask for credit card information should do so using SSL (secure socket layer). This ensures that data transmitted between the web server (Netfirms) and the web browser is encrypted and secure. Typically a secure connection is confirmed by a padlock icon tha appears in the web browser window.
  1. In place of your regular web address ( use the SSL address: or
  2. Verify that this is working by ensuring the padlock icon is displayed in the web browser when accessing your website through the address above.
Notes: A shared SSL certificate provides only basic encryption and does not contain your domain name. If you wish to secure your domain name, e.g. you can do so using a dedicated SSL certificate (see section 9.4).

9.5 How to Use a Dedicated (Third Party) SSL Certificate

  7. Upon purchasing an SSL certificate from a third party vendor you will be provided with a .CRT (Certificate) text file which looks similar to the CSR text you created earlier.

    Copy the CRT text exactly as it appears into the blank CRT text field in the Netfirms SSL Certificate manager. The CST and the CRT create a matching pair.

  8. Click the Submit button to complete the process.
Caution: Do no delete your CSR text once you have submitted it to the certificate provider. The CSR text is a unique dataset that is matched against the certificate.
