I am creating a web application. I would like to create a product key for
the app that expires after a full year of usage. Any suggestions?

Thanks,
Mark
 
Have the year from today date go through some algorithm (that can be
reversed) that will append the date to the product key.
10/26/2005 -> algorithm -> A#$DVDGF

Program reads
A#$DVDGF -> reverse algorithm -> 10/26/2005
 
I kind of want to stay away from algorithms, because they can get cracked.
That's why so many software packages these days are being cracked, because
someone figures out the algorithm.
