You can gather computer and/or user specific data (bios serial, hard drive label, MAC address on eth and wifi, User IDs etc...) with a specific program and crypt with an algorithm that your application knows. Then provide this license file with your app. Your app shall decrypt and compare information with that specific computer info several times in your app runs.

Start with Google: Protect my application with key[^] and refine your search based on your language and target environment.

But...unless you are going to charge a heck of a lot for it, or you are going to sell huge numbers I wouldn't spend too long on the process. It's very easy to end up spending more in terms of your time on implementing protection that you would save in reduced piracy - and protection is a "red flag" for some people for whom hacking past it is a hobby. Look at Adobe: they spend a lot of money on protecting Photoshop, only for a cracked version to appear on torrent sites on the same day as it it released.
And beware over-protecting: it's easy to make life difficult for genuine users, and that can have a huge adverse effect on sales.
