- Python解包及反编译: PyInstaller Extractor+uncompyle6
- 一、前言
- 二、PyInstaller Extractor解包
- 三、反编译uncompyle6工具使用
- 四、一键解包并编译
一、前言
有时候会遇到一些人制作一键安装包的时候会把一些程序封装进exe里面，但我们又想拿到里面源码的情况。在这里就涉及到了解包与反编译的。
二、PyInstaller Extractor解包
目前的python主流的打包方式是使用pyinstaller，针对这种情况可以使用pyinstaller Extractor进行解包。
- 前提
- 使用pyinstaller进行打包
- 未加密
1、安装pyinstxtractor
新建一个py文件pyinstxtractor.py,然后将下面的内容拷贝进去
然后就安装好了，要使用的时候与待解包的exe文件放在同一文件夹即可
""" PyInstaller Extractor v2.0 (Supports pyinstaller 6.6.0, 6.5.0, 6.4.0, 6.3.0, 6.2.0, 6.1.0, 6.0.0, 5.13.2, 5.13.1, 5.13.0, 5.12.0, 5.11.0, 5.10.1, 5.10.0, 5.9.0, 5.8.0, 5.7.0, 5.6.2, 5.6.1, 5.6, 5.5, 5.4.1, 5.4, 5.3, 5.2, 5.1, 5.0.1, 5.0, 4.10, 4.9, 4.8, 4.7, 4.6, 4.5.1, 4.5, 4.4, 4.3, 4.2, 4.1, 4.0, 3.6, 3.5, 3.4, 3.3, 3.2, 3.1, 3.0, 2.1, 2.0) Author : Extreme Coders E-mail : extremecoders(at)hotmail(dot)com Web : https://0xec.blogspot.com Date : 26-March-2020 Url : https://github.com/extremecoders-re/pyinstxtractor For any suggestions, leave a comment on 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> Licensed under GNU General Public License (GPL) v3. You are free to modify this source. 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.

在使用前：
将需解包的exe与下载的pyinstxtractor.py存入同级文件夹
使用命令行输入如下指令, 得到exe的解包文件夹.
python pyinstxtractor.py {exe路径} 示例: python pyinstxtractor.py CreatFoder.exe 运行结果：
解包后文件放在以exe名字+_extracted的文件夹中
三、反编译uncompyle6工具使用
目前代码还不能用，打开会看到基本全是乱码。
在这里需要对在线pyc,pyo,pyd文件等进行反编译成py文件
1、pip安装uncompyle6
pip install uncompyle6 2、找到主文件并编译
主文件的命名一般与其他库不同，有比较明显的开发者个人特征，且后缀通常是pyc。
找到之后再同级目录下输入命令行执行
uncompyle6.exe {pyc文件} >{py文件输出路径}
示例
3、解压完成查看源码
无乱码，一切正常
四、一键解包并编译
很多时候我们对于解包和编译是同一流程的。为了加快获取目标源码这一步骤，我将解包和编译的流程集中了起来，源码如下：
新建一个py文件：pyinstxtractorV2.py
