We implemented a licensing system based on public-key cryptography.
RSA is used to create a license and to very the license from within
the application.
Any kind of information can be included in the license file as well.
Moreover, it is technical impossible to generate new license files,
since
only the LinceseBuilder application can do, since only the
LicenseBuilder knows
both - the public and the private key.
Such like schema could be used to deploy demo licenses and full
licenses.

Hi,
I have a finished product and I am looking to give the users a 30-day
or maybe just a week trial.
Is there some way that I can implement this in My Cocoa/Obj-C app.
I don't want them to be able to just reinstall it and then it resets
the time.
Any out there have experience with this, I know with Applications such
as Dreamweaver, they do a good job with this
Are they hiding some file somewhere on my computer?
Any ideas?
Thanks,
Matt
