SSL certificate installer for Cpanel

SSL certificate installer for Cpanel

The PHP script takes required parameters and installs a SSL/TLS certificate using Cpanel UAPI's install_ssl function. It uses cURL to send payload to the UAPI. It uses Cpanel username and password to authenticate with the API. Connections to the API are made through HTTPS.

An working example can be found here.


The script can be used in CLI environment or by HTTP request. For HTTP request, do not use GET method (It's insecure), use POST method instead.
