You've been down this road many times before.
Your script, by definition, would include the complete and unabridged method for generating this "secret" number. How would you conceal it? If the computer can decode it, so can they, no ifs or buts. You're not going to defeat this by being clever enough, the same way you can't change the value of pi by being clever enough.
The kind of security you want can be achieved by not letting their computer read it.
