far are insecure.
How about incorporating either an expiration date or a "no expiration"
flag in encrypted form directly into the registration code? Have the
app generate its own registration code with an expiration date on first
launch. Then if a user asks for more time you can send them a new code
that expires in another week or two, and send them a permanent code
when they're ready to pay.
