Python Source Obfuscation using ASTs | Development & Security

Obfuscation techniques usually involve comments/docs stripping, name mangling, trash code insertion, and so on, so even if you decompile bytecode, you get not very readable sources. But they will be Python sources nevertheless and Python is not good at becoming unreadable mess. Python 3.3 - 3.7 are supported. Unsupported python language features. Functions that access runtime namespace ( exec, dir, locals, globals) may go wrong because of accessing objects that has been renamed. Recommendations to achieve best results. Define export list (a variable named __all__) for each module. Jul 03, 2015 · While Python is not particularly suited to code obfuscation, there are a number of possible solutions. Note that shipping only the [code]pyc[/code] (or a packaged [code]exe[/code]) is not a solution as these can be easily decompiled. One is obfuscation. I like a package called pyobfuscate. It transforms your normal and clearly written (right?) Python source code into new source code that is hard to read, by making changes to whitespace and names, stripping comments, removing functions, etc. The package doesn’t seem to be on PyPI, but you can install it from the Github repo: Jul 23, 2020 · PyArmor is a command line tool used to obfuscate python scripts, bind obfuscated scripts to fixed machine or expire obfuscated scripts. It protects Python scripts by the following ways: Obfuscate code object to protect constants and literal strings. Obfuscate co_code of each function (code object) in runtime. - The main module for minifying, obfuscating, and compressing Python code; - For analyzing Python code; - For compressing Python code; - For minifying Python code; - For obfuscating Python code; - A collection of token-related functions Jan 04, 2018 · Opy will obfuscate your extensive, real world, multi module Python source code for free! And YOU choose per project what to obfuscate and what not, by editing the config file: You can recursively exclude all identifiers of certain modules from obfuscation. You can exclude human readable configuration files containing Python code.

Takes a python source code and transform it into an obfuscated python code, replace name of variables - classes - functions to random chars and defined length, removes comments, line breaks and add to each line a random script with an always differents values.
