Windows 7: How to encrypt .zip file that will be readable from the program

Hello,
I have a zip file inside in a navigation program.
The .zip file contanins some files in UTF-8 format and some in Ansi format.
When the navi run, it goes and read the .zip file and use it while the navi run.

The problem:
I want to hide (or to encrypt) some files inside the .zip file (not to be readable from anyone, but to be readble from the navi program).

If I lock the .zip file with a password, then the program don't run (it gives intialization error).



If I encrypt the file I want not to be readable then the program run but the files inside the .zip file can not be readable from the program.

Do you know how can I encrypt (in order not to be readable by anyone ) those file inside the .zip file but on the other hand to be readable (from the running program) .

Thanks in advace.

You cannot. You have to decrypt the data for the program to read it.
If no one can read it, nothing can read it. A program is somebody (logically).

Thanks a lot.

Bytheway one more final question !

Do you know any program that can transform data from an Ansi file into unreadable data (transform the data to a code, something like code program machine ) by someone ?

I mean something like NoteCrypt, this way someone who like to read the file it can not be readable, but the program can read those file.

Too many thanks to this forum.
Thanks again for your response!!!

What about using something like TrueCrypt? Those programs can encrypt any files with a password, and create a virtual drive to access them. You may "un-hide" the files by entering the password (thus making them available for everyone) and hide them again by dismounting the virtual drive.

Thank you for your response!!
