What's the best way to protect your software from being pirated?
Suppose you have a software product being sold online. Usually, a serial number or something similar is given to the buyer after he/she downloaded and paid the software. But this is probably a very ineffective way to protect the software because the buyer can send the downloaded file together with the serial number to anyone.
A good way of protection is to setup a license server, but this would be quite inconvenient for the users because you will have to be connected to the internet to activate or use the software.
