Serial keys: What to do?
<p>I've been reading some posts here and articles around the web but I can't picture a serial keys based system for my application.</p>

<p>I read this one but I can't turn the code into Java and I'm not very familiar with the terms either.</p>

<p>What possible insight can you give me on this? Ideally my application will be for sale but I don't expect it to be much popular, I don't mind much if it gets cracked if I have users that appreciate the product and buy it, but I want to avoid it to be easily cracked. Please be as specific as you can, I'm somewhat new to Java.</p>

<p>Thanks in advance.</p>
