    .SYNOPSIS
        This script will use the free service Let's Encrypt in order to generate a certificate using a DNS challenge. Followed by activating it for the SoftEther VPN service.
    
    .DESCRIPTION 
        For a client who needed a SoftEther VPN Service I created this script in order to automate the requesting of the certificate 
        and to autmatically configuring the SoftEther VPN Server with the new certificate. 
        
        The Script uses DNS challange so it won't be neccessary to enable port 80 on the VPN Server.
