What is python obfuscation?
In software development, Obfuscation is the deliberate act of creating Source Code that is difficult for humans to understand. The Code is often obfuscated to protect intellectual property or trade secrets, and to prevent an attacker from reverse engineering a proprietary software program.
Can python be obfuscated?
There is no effective way to obfuscate python such that it can not be trivially converted back to human readable. If you have code that valuable, convert it to C, or keep it on a server.

How do I run obfuscated python?
- Use command obfuscate to obfuscate python scripts. …
- PyArmor obfuscates myscript.py and all the *. …

How can I protect my python code but still make it available to run?
Use Cython, Nuitka, Shed Skin or something similar to compile python to C code, then distribute your app as python binary libraries (pyd) instead. That way, no Python (byte) code is left and you’ve done any reasonable amount of obscurification anyone (i.e. your employer) could expect from regular Code, I think.
How do I protect a python script?
The best solution to this vulnerability is to encrypt Python source code. Encrypting Python source code is a method of “Python obfuscation,” which has the purpose of storing the original source code in a form that is unreadable to humans.
Can python be Minified?
Sure, you could uglify it, but given the fact that python relies on indentation for syntax, you couldn’t do the equivalent minification (which in JS relies largely upon removing all whitespace). Beside the point, but JS is minified to make it download faster, not obfuscate it.

How do you obfuscate code?
Encrypting some or all of a program’s code is one obfuscation method. Other approaches include stripping out potentially revealing metadata, replacing class and variable names with meaningless labels and adding unused or meaningless code to an application script.
Does PyInstaller obfuscate?
Using Cython you can convert Python modules into C and compile the C to machine language. PyInstaller can follow import statements that refer to Cython C object modules and bundle them. Additionally, Python bytecode can be obfuscated with AES256 by specifying an encryption key on PyInstaller’s command line.
Is Pyarmor secure?

How do you use Pyconcrete?
- need to input your passphrase create secret key for encrypt python script.
- same passphrase will generate the same secret key.
- installation will add pyconcrete.pth into your site-packages for execute sitecustomize.py under pyconcrete which will automatic import pyconcrete.
What is Cython good for?
Cython is a popular superset of Python. As a compiled programming language, Cython helps programmers to boost performance of code with C-like performance. The developers can load and use the extension modules directly in the Python code through the import statement. Python is an interpreted programming language.

How does Cython protect Python code?
Cython generated C code can be modified to introduce changes, improve protection, etc. Tracebacks won’t reveal code, but just line numbers (unless disabled ). Cython takes Python code and translates it to C, which is then compiled by GCC (or similar), the compiled code will run faster than the pure Python version.
How can you secure Python modules?

Can Python scripts be compiled?
Python, as a dynamic language, cannot be “compiled” into machine code statically, like C or COBOL can. You’ll always need an interpreter to execute the code, which, by definition in the language, is a dynamic operation.
What is py_compile?
The py_compile module provides a function to generate a byte-code file from a source file, and another function used when the module source file is invoked as a script.
How does code obfuscation work?
Obfuscation in computer code uses complex roundabout phrases and redundant logic to make the code difficult for the reader to understand. The goal is to distract the reader with the complicated syntax of what they are reading and make it difficult for them to determine the true content of the message.
