pyprotect's Introduction

pyprotect

pyprotect is a lightweight python code protector, makes your python project harder to reverse engineer.

Features

Cross platform
No need to install any extra dependents
Very easy to use

Only python3.x is supported by current version

How it works?

Build pyprotect

Download pybind11 library:

Create a directory "deps" in pyprotect root directory.
Download pybind11 project into the newly created deps directory.
Unzip pybind11 zip file, and change the extracted directory's name from something like "pybind11-x.x.x" to "pybind11"

Run these commands in pyprotect root directory:

mkdir build
cd build && cmake .. && make

And you can find libpyprotect.cpython-PYVERSION-PLATFORM.so in the objs directory.

Encrypt your python project

Command:

python encrypt.py -s SCRIPTS_DIR -e ENTRY_POINT_LIST -o OUTPUT_DIR [--exclude EXCLUDED_SCRIPT_LIST]

SCRIPTS_DIR is your python project root directory.
ENTRY_POINT_LIST is a comma separated list of file function pair which is directly ran as the entry point of your programme. For example "app.py:main,test_app.py:run_test".
OUTPUT_DIR is the destination directory to store the encrypted python scripts.
EXCLUDED_SCRIPT_LIST is a comma separated list of python scripts which you don't wan to encrypt.

You need to put libpyprotect.cpython-PYVERSION-PLATFORM.so into the OUTPUT_DIR as part of your programme.

Configuration [IMPORTANT]

For security reason you should change the AES key and IV, which is used to encrypt/decrypt the python scripts, to a stronger value. And you may want to change the file extension of encrypted python scripts (which is ".pye" by default).

You can find these macros or variables in config.h and encrypt.py:

PYPROTECT_KEY
PYPROTECT_IV
PYPROTECT_EXT_NAME

You need to change the two files both. Please change the PYPROTECT_KEY and PYPROTECT_IV to a safer value.

Roadmap

Support python3 scripts
Support python2.7 scripts
Anti debugging
Software license control

加密后如何运行python文件

Error al compilar en Windows x64 - Error hypot

Esta seria la solución:
1.- Instalar Mingw
2.- Instalar cmake
3.- Tener Pybind dentro de carpeta deps
4.- Tener listo el programa Codelite, con el compilador c++ configurado (mingw).
5.- Editar archivo cmath, dentro de Mingw; cambiar linea "::hypot" a "::_hypot"
6.- Abrir cmake, ingresar source, y directorio build
7.- en Cmake, configurar con los pasos hechos, y dar click en generar; Escoger compilador que se encuentra dentro de Bin en Mingw.
8.- Compilar archivo wordspace de codelite, generado en cmake, dentro de codelite.

Resultado final:
libpyprotect.cp36-win_amd64.pyd (windows)

请问这是啥错误，.net版本问题？

Python 2

When this project will support python 2? If it will be. :)

依赖包是zip文件

如果依赖包是zip文件，怎么处理呢

Windows - error padding

I run in windows, and have error with padding.

[error] padding=210

struct ModLoader {

    #ifdef DEBUG
            printf("[error] padding=%d\n", padding);
    #endif
}

how to encryp a project used celery

libpyprotect.so: undefined symbol: PyThread_tss_get

After make, i get the file "libpyprotect.cpython-37m-x86_64-linux-gnu.so", then from the same directory i do "import libpyprotect" i get ModuleNotFound error,
Then I rename it to "libpyprotect.so". Now when in python I do "import libpyprotect" from the same directory where the ".so" file is kept, i get this error:
ImportError: /home/Rishi/pyprotect/libpyprotect.so: undefined symbol: PyThread_tss_get

加密的程序启动后停止

起tornado这样的服务时候如果用加密的程序就会停止，不知道有没什么解决方法

A fork with windows support

The way pyprotect.cpp would read the file was causing errors in windows, so i did fix that.

Exclude virtual environment

Nearly everyone nowadays use virtual environment for project development. How to exclude the whole venv directory from encryption?

libpyprotect.cpython-PYVERSION-PLATFORM.so not found

I have followed the steps you given I am not able to find libpyprotect.cpython-PYVERSION-PLATFORM.so in root pyprotect directory

Windows support

Dear ga0

Could you make a new make file which can build the libpyprotect.cpython-37m-x86_64-windows-gnu.dll for windows 10?

还有计划继续支持开发吗?

python2.7的支持迫切需要阿

AttributeError: ModLoader.is_package() method is missing but is required by Flask of PEP 302 import hooks. If you do not use import hooks and you encounter this error please file a bug against Flask.

您好，感谢您提供了这个好用的工具，我用它加密了一些软件，确实没问题，但是当我在代码中使用了flask模块后，报错如下：
AttributeError: ModLoader.is_package() method is missing but is required by Flask of PEP 302 import hooks. If you do not use import hooks and you encounter this error please file a bug against Flask.
