Simple password protection for .exe files

I need a really simple thing - a program to add password protection in my .exe file so it cannt be executed without the proper pasword. I don't need any windows opening and asking for a password, i want to be able to pass the password as a command line argument. I have been searching for AGES looking for something as simple as that and i couldn't find anything. Please if someone knows something that can help me - share your information.
