我建议：不要花太多时间来保护钥匙。
使用字节编译语言，很容易进行反编译，只需使应用程序跳过验证步骤。无论钥匙多么安全，当您的验证功能始终返回true时，它们无关紧要。系列键可以保持诚实的人诚实。

has feature2:
has feature3:

e.g. Acme Inc 5.0 20081102 20081102 0 1 0

解决方案

I would recommend: Don't spend too much time on securing your keys. With byte compiled languages it is very easy to decompile and just make the application skip the validation step. No matter how secure your keys are, they don't matter when your validation function always return true. Serial keys are there to keep honest people honest.
