is it possible to get a passcode from an .exe? i tried looking at it with ollydbg after using some of the online tutorials and i can't seem to come up with anything.

does anyone have a not-too-complicated way to use ollydbg to try to find it?

Well this is not descriptive at all. The passcode you mention could be anywhere.
First of all look at strings, it might be there. The second thing I would do is follow the execution until you get to the part you are interested in. If you are interested in knowing the passcode you might have to reverse the logic of the encryption, else just try to crack the .exe

This is the first result that I got but it shows in a practical way how to do it:
What sort of passcode? Is the exe protected from running by a password?
