    It's not trivial - I'd suggest you find some good quality software to use rather than write your own, but if you do write your own, it will need to do better than the ones described here.

    It's very difficult to create something like this in Java because someone can fairly easily reverse engineer your program from the Java bytecode. Even programs written with langauges that compile down to machine code can be cracked.

    It all depends on how much security you want, how much of an inconvenience you want to make your program for the users, and how much research/work you are willing to do.

    Here's a webpage that gives some tips on how to protect your software from potential cracking: (note that eventually, some douche is probably going to figure out how to crack your program)

    The application in question here is a private application and needs to expire on a given date and it should deactivate itself on system backdate. When the application expire's, it should lock the major features of the application.Thats a brief of what the module should...thanx
