取决于客户是谁，一个简单的保护机制，结合合理的许可协议将比任何复杂的许可/加密/混淆系统更有效。

最好的解决方案是将代码作为服务出售，比如托管服务，或者提供支持——尽管这并不总是可行的。

以.pyc文件的形式发布代码可以防止你的保护被一些#所破坏，但这几乎不是有效的反盗版保护(就像有这样的技术一样)，而且归根结底，它不应该达到任何与公司签订像样的许可协议所能达到的效果。

专注于让你的代码尽可能好用——拥有满意的客户会让你的公司赚更多的钱，而不是防止一些理论上的盗版。

在某些情况下，可以将软件(全部或至少关键部分)移动到组织托管的web服务中。

这样，许可证检查就可以在您自己的服务器机房的安全环境中执行。

我记录了如何通过将其转换为.so文件和将其转换为python轮文件来混淆python: https://github.com/UM-NLP/python-obfuscation

如果我们关注软件许可，我建议看看我在这里写的另一个Stack Overflow答案，以获得如何构建许可密钥验证系统的灵感。

GitHub上有一个开源库，可以帮助您进行许可证验证。

你可以通过pip安装许可来安装它，然后添加以下代码:

pubKey = "<RSAKeyValue><Modulus>sGbvxwdlDbqFXOMlVUnAF5ew0t0WpPW7rFpI5jHQOFkht/326dvh7t74RYeMpjy357NljouhpTLA3a6idnn4j6c3jmPWBkjZndGsPL4Bqm+fwE48nKpGPjkj4q/yzT4tHXBTyvaBjA8bVoCTnu+LiC4XEaLZRThGzIn5KQXKCigg6tQRy0GXE13XYFVz/x1mjFbT9/7dS8p85n8BuwlY5JvuBIQkKhuCNFfrUxBWyu87CFnXWjIupCD2VO/GbxaCvzrRjLZjAngLCMtZbYBALksqGPgTUN7ZM24XbPWyLtKPaXF2i4XRR9u6eTj5BfnLbKAU5PIVfjIS+vNYYogteQ==</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>"

res = Key.activate(token="WyIyNTU1IiwiRjdZZTB4RmtuTVcrQlNqcSszbmFMMHB3aWFJTlBsWW1Mbm9raVFyRyJd",\
                   rsa_pub_key=pubKey,\
                   product_id=3349, key="ICVLD-VVSZR-ZTICT-YKGXL", machine_code=Helpers.GetMachineCode())

if res[0] == None not Helpers.IsOnRightMachine(res[0]):
    print("An error occured: {0}".format(res[1]))
else:
    print("Success")

“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.

使用cxfreeze (Linux的py2exe)可以完成这项工作。
