How do you protect your software from illegal distribution? [closed]
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . I am curious about how do you protect your software against cracking, hacking etc. Do you employ some kind of serial number check? Hardware keys? Do you use any third-party solutions? How do you go about solving licensing issues? (e.g. managing floating licenses) EDIT: I'm not talking any open source, but
