This is what has me worried. It'll be really easy to just turn the
relevant check into a NO-OP. No matter how advanced the actual
license checking is, as long as this is an option, crackers won't be
hindered much. Moreover, this is Objective C we're talking about.
With all the dynamic runtime dispatch stuff it has, and its
introspection abilities, I gather it'd be ridiculously easy to locate
the actual version-checking code.
So, if I'd do this at all, I'd probably settle for a proprietary
solution, not open source (even if it's BSD), because in this case,
security through obscurity at least means that the crackers will have
to crack applications one-by-one. If there is a standardized library,
they'd just have to crack that one library, and from then on every
ijit could crack other apps using it.
As long as my hand-grown code is good enough to thwart casual piracy,
it really doesn't matter if the passwords are generated using an
encryption that isn't state-of-the-art. If they want to crack my app,
they'll find a way. IMHO it's not worth the hassle trying to
discourage use by people who wouldn't have bought my app anyway,
especially since it may be an annoyance to those users who *have*
actually paid.
Of course, I'm doing mainly Freeware and contract work right now.
Maybe my priorities will change once my income depends on the
effectiveness of my licensing scheme, who knows?
