request code generator?


Do you know where to find some peace of software/code which I can
implemented in my desktop java application which will protect it from
illegal using?
I imagine something like: buyer can install my software by using request
code which will generate on my web. It must be unique for that machine, I
suppose.
- it doesn't matter if generator can be cracked. I will proud to someone
want crack my piece of software.:))
- I think that I was looking for a code generator but you can suggest me
some other way of protection.

As far as I know, a code generator is the final stage of a compiler
after parsing, optimizing etc.

I suspect you want to do a shareware app with unlock capability. In that
case, it really not hard to do yourself. As long as you obfuscate your
code. Use these tricks:

My english is not very well, so I think that I didn't explain very well what
is on my mind.
I want to protect my java desktop application from ilegall installation.
Like other commercial sofware which needs some request code to install it.
Why would someone who didn't pay some real price be in oportunity to use my
application, which isn't something revolutionary, but it is useful for a
special group of users?
