About the BitBoost Python Code Obfuscator

The most mature, well-debugged, and featureful
Python obfuscator and code size reducer available

Obfuscator Overview

Fight reverse engineering.

Your Python code contains
- lots of information that you use to understand and improve your code,
- but that information also helps reverse engineers.
Unless you use a high-quality obfuscator, much of this information is preserved even by normal conversions such as compilation to bytecode.
Remove that information automatically by using BitBoost obfuscation technology.

Useful against even bytecode disassemblers and decompilers.

Obfuscate even the interfaces between these components, to create a single unit of greater confusion.

Code shrinking options can reduce code size.

Automated analysis and obfuscation of the names defined by your code.

Renames variables, functions, function attributes, function and method arguments, classes, class and object methods, class and object variables, objects, modules...
Namespace analyzer optionally avoids a 1:1 mapping of cleartext names to obfuscated names.
- The same variable name or function parameter name may be converted to several different names within a piece of obfuscated code, without changing code functionality nor increasing the number of code instructions.
You can choose the format of replacement names.
- Choose to shrink code more with smaller names.
- Choose extra-confusing formats (e.g. containing fake 'red herring' information.)
- Choose to have different names for each customer's build (a code watermarking feature.)
You may mark some names and docstrings for retention (mostly so you can produce libraries for other programmers to use.)

Removes/replaces documentation strings (docstrings).

Removes comments.

'Industrial-strength' automation can obfuscate even large-scale programs and libraries consisting of many modules, packages, subpackages.

No limitations on import syntax.
A body of code containing multiple packages and subpackages can even be obfuscated as a coordinated unit, within which even the interfaces between the packages and subpackages are obfuscated.
Handles even non-default and complicated call parameter arrangements such as keyword arguments, variable argument lists, etc.
Special support for metaprogramming and advanced monkeypatching.

Outputs Python source code for maximum flexibility.

Python source code can easily be byte-compiled or converted to other formats, using any tool that accepts/supports Python code.

Cross-platform portability:

Runs on OS X, Windows, Linux/UNIX, and other platforms that support standard Python.
Runs under Python versions 2.5, 2.6, and 2.7.
Code to be obfuscated may include
- all Python 2.3, 2.4, and 2.5 language & library features.
- almost all language & library features added in Python 2.6 and/or 2.7.
Obfuscated output code can be run in Python 2.3, 2.4, 2.5, 2.6, and 2.7 (if the code you fed into the obfuscator could run in those versions of Python.)
Python 3 compatibility options: you can use from __future__ import ... in supported ways to make your code compatible with both Python 2.7 and Python 3, so the obfuscator will output similarly compatible code.

Interoperability facilitates integration into your build process.

Psychologically inspired techniques produce extra confusion in human readers.
