I have created a tool at work that required some extensive coding. I'm
being asked to distribute it a bit wider than originally intended. I
want to hide the code so no one can see, edit or hack it.

I obviously have password protected it which blocks it from viewing
etc. but I want to be a bit more secure if possiable. (I've read of
password hacking tools out there.)
What is the best way to protect your code in a workbook?

Thanks,
Jamie
