Obfuscating it is not a problem for me, but I explained it if you just sell it 1 time, he can use the same key you gave it, and the app to resell it.
Here is a little Security that:
Update by network the data, and save it to a file(encrypt the network data and the file data to a triple DES, you could just make it check just one time and done, and then checking with the file).
If you want to make it 1 tool per system you can simply query the win32_BaseBoard, for the motherboard serial number and model, and part number, etc. then save it to the encrypted file(if he wants to use the tool on another system he could just needs to register on that system).
yes its great idea but i'm not pro in vb.net i can use a free hosting for check some text file...the programm will check the key...and if i change some chars in text file the programm will be "offline" and not wokring...i will work on it with this way....your way is a bit difficult
