通过散列和签署重要文件并使用公钥方法检查，用标准加密方案为代码签名如何?

通过这种方式，您可以为每个客户颁发带有公钥的license文件。

另外，你可以使用python混淆器，就像这个(谷歌一下)。

“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.

你的雇主是否意识到他可以“偷”回其他人从你的代码中得到的任何想法?如果他们能读懂你的作品，你也能读懂他们的。也许看看你如何能从这种情况中受益，会比担心你可能会失去多少，获得更好的投资回报。

[编辑]回答尼克的评论:

没有得到也没有失去。客户得到了他想要的东西(因为他自己进行了更改，所以已经为此付费了)。因为他没有发布变更，就好像它没有发生在其他人身上一样。

现在如果客户出售软件，他们必须更改版权声明(这是非法的，所以你可以起诉并且会赢->简单的案件)。

如果他们不更改版权声明，第二级客户就会注意到软件来自您的原创，并想知道发生了什么。很有可能他们会联系你，这样你就会了解到你的作品被转售的情况。

同样，我们有两种情况:原来的客户只卖了几份。这意味着他们并没有赚到多少钱，所以为什么要麻烦呢。或者是销量。这意味着你有更好的机会了解他们的工作，并为此做些什么。

But in the end, most companies try to comply to the law (once their reputation is ruined, it's much harder to do business). So they will not steal your work but work with you to improve it. So if you include the source (with a license that protects you from simple reselling), chances are that they will simply push back changes they made since that will make sure the change is in the next version and they don't have to maintain it. That's win-win: You get changes and they can make the change themselves if they really, desperately need it even if you're unwilling to include it in the official release.

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

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。

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。
