推荐答案

我建议:不要花太多时间来保护您的密钥.使用字节编译语言很容易反编译，只需让应用程序跳过验证步骤.无论您的密钥有多安全，当您的验证函数始终返回 true 时，它​​们都无关紧要.序列号可以让诚实的人保持诚实.

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.
