serial number for my application
-
i've made an application, i want to create an algorithmic to handle a serial number inputted by the user at the first running of the application, and understand if it is one of possible (correct) or not, in this way unlock or not the appliction. Where can i start by? How can avoid hacker see my assembly algorithm?

Almost no such method is hacker-free. Only thing is how more difficult you can make it. You can use some hardware-related factors to create your serial numbers / copy-locking methods. You can also have some method to create some random number at the time of the first run of the software. But, you'll have to create your own algorithm. Search "serial number" in Code Project articles, and you'll get some useful material. Here is the first article in this search: http://www.codeproject.com/csharp/hard_disk_serialNo.asp[^] Alternatively, you can consider some third-party solution. Google with phrases such as "copy protection", "software protection", and the like, and you'll get tons of such third-party applications.
