License Key Generation[^]

hope this helps :)

当您的应用程序第一次启动时，此时创建一​​个原始密钥，其中包含

系统的MAC地址，

当前日期时间，和

其他详细信息。



然后用任何算法加密原始密钥。



创建另一个应用程序（许可证生成器），它将解密原始密钥并为您生成许可证密钥。



许可证密钥将包含详细信息of：

MAC地址（来自原始密钥）

当前日期时间（来自原始密钥）

应用程序类型（演示或许可证）（来自许可证生成器）

如果演示到期日（来自许可证生成器）



然后加密许可证详细信息



然后取得该许可证关键并将其投入实际应用。



每次开始你都可以查看到期日。



您可以将原始密钥和许可证密钥存储在数据库，应用程序属性或配置文件中。

When your application start at first time, at that time create a raw key which will contain
MAC address of system,
Current DateTime, and
additional details.

Then encrypt the Raw key with any algo.

Create another application (License Generator) which will decrypt the raw key and generate a license key for you.

License key will contain the details of :
MAC address(from raw key)
Current DateTime(from raw key)
Application Type (Demo or License) (from License Generator)
If demo that Expiry days (from License Generator)

Then encrypt the license details

Then take that license key and put it into actual application.

On every start you can check the expiry days.

You can store the Raw Key and License Key in Database, application Properties or in config file.

至于跟踪试用版安装日期的问题，您可以参考在哪里 [ ^ ]因为这也是之前提出的一个问题。



一个朋友提醒，永远不要将您的问题作为解决方案发布。相反，将其作为对解决方案的评论发布，或者如果它是一个不同的问题，您可以创建一个新问题。

As for your problem regarding tracking the date installed for trial versions, you may refer here[^] as this was also a question asked before.

A friendly reminder, never post your questions as a solution. Rather, post it as a comment to the solutions, or you can create a new question if its a different issue.
