Info:  This tool helps you to automate the obfuscation process of
       any script written in PowerShell with different techniques

Usage: .\Invoke-Stealth.ps1 script.ps1 -technique Chimera
         - You can use as single or separated by commas -

Techniques:
       · Chameleon: Substitute strings and concatenate variables
       · BetterXencrypt: Compresses and encrypts with random iterations
       · PyFuscation: Obfuscate functions, variables and parameters
       · ReverseB64: Encode with base64 and reverse it to avoid detections
       · PSObfuscation: Convert content to bytes and encode with Gzip
       · All: Sequentially executes all techniques described above

Warning: The output script will exponentially multiply the original size
         Chameleon & PyFuscation need Python3 to work properly
