我很惊讶，在任何回答中都没有看到“具体”。也许是因为它比问题更新?

它可能正是你所需要的。

它不会混淆代码，而是在加载时对代码进行加密和解密。

来自pypi页面:

保护python脚本工作流程 Your_script.py导入pyconcrete Pyconcrete将钩子导入模块 当你的脚本导入MODULE， pyconcrete导入钩子将尝试查找MODULE。先撒，再撒 解密模块。Pye via _pyconcrete。Pyd并执行解密的数据(如 .pyc内容) 加密和解密_pyconcrete.pyd中的密钥记录 (如DLL或SO)的秘密密钥将隐藏在二进制代码，不能 直接在HEX视图中看到它

另一种让代码更难被窃取的方法是使用jython，然后使用java混淆器。

这应该工作得很好，因为jythonc将python代码转换为java，然后将java编译为字节码。因此，如果混淆了类，就很难理解反编译后会发生什么，更不用说恢复实际的代码了。

jython的唯一问题是你不能使用用c编写的python模块。

使用cxfreeze (Linux的py2exe)可以完成这项工作。

它可以在ubuntu存储库中找到

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.

我理解您希望客户使用python的强大功能，但又不想公开源代码。

以下是我的建议:

(a)以C或c++库的形式编写代码的关键部分，然后使用SIP或swig将C/ c++ api公开给Python名称空间。

(b)使用cython而不是Python

(c)在(a)和(b)中，应该可以将库作为带有Python接口的许可二进制文件分发。
