- Not possible. You can only make things tedious and difficult, but that will not
- thwart a resourceful and sophisticated enemy.
-
- You see, the code must always be intelligible to the CPU, and the actions of a
- CPU are neatly deterministic.
-
- Your program will, at some point, need to decrypt the string, and this
- execution can be traced.
-
- What you can do is never decrypt the string, but this is probably useless to
- you :)
