# Code Flow Protection

The goal of this protection is to " spaghettify " the code execution flow while keeping its original functionality. That means the code should execute the same original tasks and instructions while providing a numbers of new proxy flow within the method. 

The new method flow is meant to prevent hackers from understanding the method flow with ease.
