Python文件反编译，还原代码（xxd、uncompyle6）

这里有难度的就是如何复制文件的完整内容，如果能直接下载既下载，否则就要用方法完整拷贝内容

首先复制文件的十六进制的内容

xxd命令转换二进制文件为十六进制文件

xxd .configuration.cpython-38.pyc

然后把显示出的东西都复制放在kali文件里，再就是十六进制转换成二进制

xxd -r configure.pyc >> configure1.pyc

再进行还原文件

这里要提前在下一个python还原文件的工具uncompyle6

uncompyle6可将python字节码转换回等效的python源代码，它接受python 1.3版到3.8版的字节码，这其中跨越了24年的python版本，此外还包括Dropbox的Python 2.5字节码和一些PyPy字节码。

github项目：GitHub - rocky/python-uncompyle6: A cross-version Python bytecode decompiler

pip install uncompyle6

（事实上，pip install uncompyle2 也会跳到安装uncompyle6） 

uncompyle6 configuration1.pyc > configuration.py

configuration.cpython-38.pyc
