python2.6 pyc反编译

来源：互联网发布：照片数据恢复编辑：程序博客网时间：2024/05/29 13:24

同学请我帮他反编译下几个pyc文件，生成pyc文件的python版本是2.6.6

尝试了以下几个工具：

【1】uncompyle2

github：https://github.com/wibiti/uncompyle2

之前用过，但是有个限制是必须是python2.7以上生成的pyc

怀着试试的心理，还是按照说明使用了：

E:\kkxue文档\python\反编译\uncompyle2-master\scripts>python uncompyle2 log_error.pycError:  uncompyle2 requires Python 2.7.

好了，下一个

【2】UnPyc

github：https://github.com/tswr/UnPyc

直接上执行后的结果：

C:\Users\Administrator\Desktop\zhou\UnPyc-disasm_0.18>python UnPyc -dv log_error.pyc > result.txt

打开result.txt,结果发现是汇编代码：

但是看不懂，就算看得懂，也不直观啊，这位作者还明白地说，反编译功能还未实现！

if 'D' in sys.argv[1]:print "# --== Decompile ==--"print ">>> not implemented yet"

没办法，下一个（不过UnPyc以后学习了汇编会很有用）

【3】pyc2py

github:https://github.com/eduble/pyc2py

执行时报一个错误：

[root@netbase3_7road pyc2py-master]# python main.py ./test/log_error.pyc ./test/log_error.pyTraceback (most recent call last):  File "main.py", line 39, in ?    mod = __import__(module_name)ImportError: Bad magic number in ./test/log_error.pyc

查了下资料主要是python版本不匹配导致

即生成pyc的python版本和目前反编译pyc的python版本不一致导致

如我现在的版本就是python2.4：

[root@netbase3_7road pyc2py-master]# python Python 2.4.3 (#1, Jan  9 2013, 06:47:03) [GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>>

安装了python 2.6之后（额外安装，即make altinstall），就解决了这个问题.

[root@netbase3_7road pyc2py-master]# python2.6 main.py ./test/log_error.pyc > ./test/log_error.py[root@netbase3_7road pyc2py-master]# cat ./test/log_error.py[root@netbase3_7road pyc2py-master]#

但是发现反编译没有成功！

这时候你会恼火吗？？？

为什么不再找找？

直接有个免费的反编译的网站可以使用：http://depython.com/index.php

但是注意版本只支持python 2.0到2.6.

我上传测试pyc之后ok,出来了！！！
