推荐答案

我会建议：不要花太多时间在保护你的钥匙。 编译字节语言是很容易反编译，只是使应用程序跳过验证步骤。不管如何保护你的密钥，它们都不重要，当你的验证函数总是返回true。串行键也保持诚实的人诚实。

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.
