Nope. You can make it marginally more difficult (encrypted) but you
can't "prevent" it entirely .. and the harder you try to make it, the
more fun you make it for crackers to reverse-engineer.
About the best you could do to hide the "super secret sauce" (lol ..
Vladis) is put it on a secure token (eg: SmartCard) and call it from
there. While not foolproof, hardware is [generally] more difficult to hack.
