🧰 KryptDis

KryptDis is a tool that can be used to find the source code of any Python File! <br> This includes...

• Obfuscated .py files
• PyInstaller/Nuitka Packed .exe files

---

🤔 How does it work?

KryptDis is a .dll file, which can be injected into Python processes. <br> When injected, it executes a code which will get the source code of your script. <br> You can see the code of the disassembler by opening "Disassembler.py"

Once injected, the program will close and a text file will open. <br> This text file contains a report of what it found. <br> This includes the assembly of all functions, content of all variables, imported modules, and URLs!
