Extracting encrypted pyinstaller executables

It has been more than a quarter since the last post, and in the meantime, I was very busy and did not have the time to write a proper post. The good news is at the moment, I am comparatively free and can put in a quick post. 

As said earlier, PyInstaller provides an option to encrypt the embedded files within the executable. This feature can be used by supplying an argument --key=key-string while generating the executable. 

Detecting encrypted pyinstaller executables is simple. If  pyinstxtractor is used, it would indicate this as shown in Figure 1.
