Thanks for the tips. What I'm primarily looking for is a way to store
registration key/trial expiration data in a way that is least visible to the
user. For an OS X application, is there a way to store this type of data in
its plist file?
If I store the data in a text file, regardless of encoding mechanism, the
user could potentially find the file and delete it, thereby starting the
trial period for the application anew. I noticed in a couple of Cocoa
shareware apps that I tried, that if I deleted their pList files in
Preferences, it did not affect their trial periods, i.e., a 10-day trial
that had been down to 8-days remained at 8-days even though I deleted its
corresponding plist file. In incidences like these, where is that data
stored that says how much time is left on a trial or that the copy has
already been registered?
Many thanks,

From a Rev application, how does one go about creating and writing

anyone can get into so easily?
There are many good options for protecting data. In addition to the other
suggestions posted here, if your security needs are modest there's a very
lightweight but reasonably efficient and easy-to-use encryption handler

Most more "industrial strength" encryption you might also consider Rev's
Blowfish implementation, included in the Studio and Enterprise packages.
