In order to add SSL to your site, you will require a CSR (Certificate Signing Request) file. We will need a set of questions to be answered by you and using that we will create the CSR file for you and mail it to you.
To generate your CSR, please send us a request by filling and submitting this form : CSR Request Form
To find out which SSL certificate to buy and from where, you can go through this : SSL buying guide
You will receive a signed certificate file after the CA signs the request. You can forward that file to us and then we will do the rest.
You can also install the Free LetsEncrypt SSL on your sites hosted of Personal Plans and above. To know more about the Free SSL, Click here
