If you are a reseller you can generate an SSL signing request via WHM --> Generate a SSL Certificate and Signing Request  If you have a shared account you can generate a CSR (SSL signing request) by logging into Cpanel --> SSL/TLS Manager --> Generate, view, or delete SSL certificate signing requests. --> Fill in the fields below "Generate a New Certificate Signing Request" and click "Generate". Note: Make sure you use your domain as either www.domain or domain.com as the host. However it is set in the CSR is how it will load when the SSL certificate is installed. Either as https://domain or https://www.domain
