No, that's stretching the definition of security-by-obscurity all out
of proportion... Some things in security _have_ to be obscure. Your
password, for example. Or the primes used to generate your PGP private
key.

Security-by-obscurity refers to securing things by relying on the
obscurity of the _processes and functionality_ behind the security system,
instead of the _data_ used to secure it. It's a bad idea because
_processes and functionality_ is a much smaller search domain than
_data_.

Of course Pacman didn't influence us as kids. If it did,
we'd be running around in darkened rooms, popping pills and
listening to repetitive music.
