pyinstaller 打包exe 防反编译(加密)

如果对安全性要求不高，可以选择直接将py文件，打包成exe即可，解压出来的是pyc文件，pyc文件还原成源码，也是有一定复杂度的，相对而言也是有一定的安全性的

在源文件同级目录下创建build文件

buidl_pyd.py

# -*- ecoding: utf-8 -*-
# @ModuleName: build_pyd
# @Function: 
# @Author: darling
# @Time: 2022-11-12 14:58

# -*- coding: utf-8 -*-

from distutils.core import setup
from Cython.Build import cythonize

setup(
    name='any words.....',
    ext_modules=cythonize(["you_source_file.py", ]
                          ),
)

打开cmd执行 python .\build_pyd.py build_ext --inplace
同级目录下会生成一个.pyd的文件you_source_file.cp39-win_amd64.pyd
修改成和源文件名一致

同级目录下创建一个main.py的入口文件

注意：

1、程序的__main__入口只能有一个，如果源py文件中有定义main入口，需要注释掉并调整代码缩进，否则通过main.py调用pyd文件遇到if name == ‘main’:之后的代码都不会运行。
2、源文件you_source_file.py文件头部import到的第三方库需全部复制到main.py文件头部，不然运行会闪退，相当于是，引用包没打进去

main.py

import you_source_file

if __name__ == '__main__':
    you_source_file()

pyinstaller打包时，执行main方法进行打包

扩展

包解压命令

在exe同路径文件中放入pyinstxtractor.py文件
cmd运行python pyinstxtractor.py .\main.exe
将exe解包，会得到相应的文件，如果是pyd文件，则是安全的，如果直接打包，则解压出来的是pyc文件，不安全pyinstxtractor.py

PyInstaller Extractor v1.9 (Supports pyinstaller 3.3, 3.2, 3.1, 3.0, 2.1, 2.0)

https://forum.tuts4you.com/topic/34455-pyinstaller-extractor/

This script extracts a pyinstaller generated executable file.
Pyinstaller installation is not needed. The script has it all.

For best results, it is recommended to run this script in the
same version of python as was used to create the executable.
This is just to prevent unmarshalling errors(if any) while
extracting the PYZ archive.

Usage : Just copy this script to the directory where your exe resides
        and run the script with the exe file name as a parameter

C:\path\to\exe\>python pyinstxtractor.py <filename>
$ /path/to/exe/python pyinstxtractor.py <filename>

CHANGELOG
================================================

Version 1.1 (Jan 28, 2014)
-------------------------------------------------
- First Release
- Supports only pyinstaller 2.0

Version 1.2 (Sept 12, 2015)
-------------------------------------------------
- Added support for pyinstaller 2.1 and 3.0 dev
- Cleaned up code
- Script is now more verbose
- Executable extracted within a dedicated sub-directory

(Support for pyinstaller 3.0 dev is experimental)

Version 1.3 (Dec 12, 2015)
-------------------------------------------------
- Added support for pyinstaller 3.0 final
- Script is compatible with both python 2.x & 3.x (Thanks to Moritz Kroll @ Avira Operations GmbH & Co. KG)

Version 1.4 (Jan 19, 2016)
-------------------------------------------------
- Fixed a bug when writing pyc files >= version 3.3 (Thanks to Daniello Alto: https://github.com/Djamana)

Version 1.5 (March 1, 2016)
-------------------------------------------------
- Added support for pyinstaller 3.1 (Thanks to Berwyn Hoyt for reporting)

Version 1.6 (Sept 5, 2016)
-------------------------------------------------
- Added support for pyinstaller 3.2
- Extractor will use a random name while extracting unnamed files.
- For encrypted pyz archives it will dump the contents as is. Previously, the tool would fail.

Version 1.7 (March 13, 2017)
-------------------------------------------------
- Made the script compatible with python 2.6 (Thanks to Ross for reporting)

Version 1.8 (April 28, 2017)
-------------------------------------------------
- Support for sub-directories in .pyz files (Thanks to Moritz Kroll @ Avira Operations GmbH & Co. KG)

Version 1.9 (November 29, 2017)
-------------------------------------------------
- Added support for pyinstaller 3.3
- Display the scripts which are run at entry (Thanks to Michael Gillespie @ malwarehunterteam for the feature request)
