用同样的方法保护c/c++的二进制文件，即对可执行文件或库二进制文件中的每个函数体进行混淆，在每个函数项的开头插入指令“跳转”，跳转到特定的函数来恢复混淆的代码。字节码是Python脚本的二进制代码，所以

首先编译python脚本代码对象 然后迭代每个代码对象，将每个代码对象的co_code混淆如下所示

    0   JUMP_ABSOLUTE            n = 3 + len(bytecode)

    3
    ...
    ... Here it's obfuscated bytecode
    ...

    n   LOAD_GLOBAL              ? (__pyarmor__)
    n+3 CALL_FUNCTION            0
    n+6 POP_TOP
    n+7 JUMP_ABSOLUTE            0

将混淆的代码对象保存为.pyc或.pyo文件

那些模糊的文件(。Pyc或.pyo)可以被普通的python解释器使用，当这些代码对象第一次被调用时

First op is JUMP_ABSOLUTE, it will jump to offset n At offset n, the instruction is to call a PyCFunction. This function will restore those obfuscated bytecode between offset 3 and n, and put the original byte-code at offset 0. The obfuscated code can be got by the following code char *obfucated_bytecode; Py_ssize_t len; PyFrameObject* frame = PyEval_GetFrame(); PyCodeObject *f_code = frame->f_code; PyObject *co_code = f_code->co_code; PyBytes_AsStringAndSize(co_code, &obfucated_bytecode, &len) After this function returns, the last instruction is to jump to offset 0. The really byte-code now is executed.

有一个工具Pyarmor可以通过这种方式混淆python脚本。

有一个关于隐藏python源代码的全面答案，可以在这里找到。

讨论的可能技术有: -使用编译字节码(python -m compileall) -可执行文件创建者(或安装程序，如PyInstaller) 软件即服务(在我看来，这是隐藏代码的最佳解决方案) - python源代码混淆器

使用Cython。它将您的模块编译为高性能的C文件，然后这些C文件可以编译为本机二进制库。与.pyc字节码相比，这基本上是不可逆转的!

我已经写了一篇关于如何为Python项目设置Cython的详细文章，请查看:

使用Cython保护Python源代码

“有没有解决这个问题的好办法?”不。没有什么可以防止逆向工程。甚至DVD机器上的固件也被逆向工程，AACS加密密钥被暴露。这还是不顾DMCA规定的刑事犯罪。

由于没有任何技术方法可以阻止客户阅读您的代码，所以您必须应用普通的商业方法。

Licenses. Contracts. Terms and Conditions. This still works even when people can read the code. Note that some of your Python-based components may require that you pay fees before you sell software using those components. Also, some open-source licenses prohibit you from concealing the source or origins of that component. Offer significant value. If your stuff is so good -- at a price that is hard to refuse -- there's no incentive to waste time and money reverse engineering anything. Reverse engineering is expensive. Make your product slightly less expensive. Offer upgrades and enhancements that make any reverse engineering a bad idea. When the next release breaks their reverse engineering, there's no point. This can be carried to absurd extremes, but you should offer new features that make the next release more valuable than reverse engineering. Offer customization at rates so attractive that they'd rather pay you to build and support the enhancements. Use a license key which expires. This is cruel, and will give you a bad reputation, but it certainly makes your software stop working. Offer it as a web service. SaaS involves no downloads to customers.

不要依赖混淆。正如你的正确结论，它提供的保护非常有限。 更新:这里有一个论文的链接，它在Dropbox中逆向工程混淆的python代码。操作码重映射方法是一个很好的障碍，但显然它是可以被击败的。

相反，正如许多海报所提到的那样:

不值得花时间进行逆向工程(你的软件这么好，花钱是有意义的) 如果可行的话，让他们签订合同并进行许可证审核。

或者，就像强大的Python IDE WingIDE所做的那样:放弃代码。没错，把代码送出去，让人们回来进行升级和支持。

发布.pyc文件有它的问题-它们与创建它们时使用的python版本以外的任何其他python版本都不兼容，这意味着您必须知道产品将运行的系统上运行的python版本。这是一个非常有限的因素。
