.SYNOPSIS
Checks hash against filehash of a file
.DESCRIPTION
Invoke-IcingaCheckCheckSum returns either 'OK' or 'CRITICAL', whether the check matches or not.
More Information on https://github.com/LordHepipud/icinga-module-windows
.FUNCTIONALITY
This module is intended to be used to check a hash against a filehash of a file, to determine whether changes have occured.
Based on the match result the status will change between 'OK' or 'CRITICAL'. The function will return one of these given codes.
.EXAMPLE
PS> Invoke-IcingaCheckCheckSum -Path "C:\Users\Icinga\Downloads\test.txt"
[OK] CheckSum C:\Users\Icinga\Downloads\test.txt is 008FB84A017F5DFDAF038DB2FDD6934E6E5D9CD3C7AACE2F2168D7D93AF51E4B
