Return pack(cpuId()+ biosId()+ diskId()+ baseId()+ videoId()+ macId()) In this post, I will get into the details of generating the unique fingerprint for the user's system.įirst of all, you need to add the following references to your project.įor doing this, navigate to Project in the Menu Bar-> Add References->.Net When you get these IDs, you can generate any key of your preferable format.

The key can be generated using the unique id of the client's computer motherboard, BIOS and processor. However, the important thing to decide is, which devices to consider while generating the fingerprint.įor licensing purposes, the best and secure way is to generate a unique key for the client's machine and provide a corresponding license key for that key. There can be various methods of generating the hardware fingerprint, using different languages. Generating a hardware fingerprint is the most commonly sought technique to ensure security in case of softwares.
