I've been a linux admin for 13 years so I know my way around a linux server. But I'm a noob when it comes to cpanel API. So I apologize in advance for my ignorance. I have created a global header template. /var/cpanel/customizations/includes/global_header.html.tt It works great. However, the part where I'm stuck, I have a string inside this template that I need to convert using MD5 or SHA1. I've been unable to access the perl module MD5 or SHA inside the template. Anyone have any ideas on maybe how to access an MD5 function inside the template? Or maybe I need to write a perl plugin that returns the md5 string to the template.
