If you already have your SSL Certificate and just need to install it, see SSL Certificate Installation | Ensim for Apache.
How to generate a CSR in Apache Ensim Web Server
Ensim makes the request process easy for the Apache user. First, log in to the Site Administrator and select which site you want to manage, then click on Services.
Click on the Actions box next to Apache Web Server (at or near the top of the services list).
Then choose SSL Settings from the Apache Web Server Manager.
Click on Generate. You will be prompted for information about your business and your server -- your Common Name will be entered automatically. Then click on Save.
This will generate the CSR and the RSA Key, both of which are necessary for the installation of your certificate.
Copy and paste the CSR (including the BEGIN and END tags) into the DigiCert order form.
After you receive your SSL Certificate from DigiCert, you can install it.
