问题描述

基本上，输入是：

公司名称_
主要版本号_

日期已创建_
到期日期_ $ b has feature1：

has feature2：

has3：

例如Acme Inc 5.0 20081102 20081102 0 1 0

我建议：不要花太多时间保护你的钥匙。
使用字节编译语言，它很容易反编译，只是使应用程序跳过验证步骤。无论你的密钥是多么安全，当你的验证函数总是返回true时，它们没有关系。串口钥匙是诚实的人。

I want to create a license key, which cryptography algorithm would you recommend?

Basically the inputs would be:

date created
expirey date
has feature1:
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.
