### 1 ### This script enables you to create thousands of SSL vhost files very quickly & easily
###       Just put the subdomain names into a file called vhost-list.txt

### 2 ### This is the script that you will need to run if you enable SSL here : by https://pastebin.com/gkTeHPDN 

### 3 #### This script need file /etc/letsencrypt/options-ssl-apache.conf to work 
###        Copy-paste this pastebin to that file : https://pastebin.com/3qrGfSft
