Here is one explicitly defined way to do it.
1. create a file with 600 permissions just for the user, in a directory with 700 permissions.
We'll call the file .data
2. use crpyt (comes with most unixes)
3. Now we have the key (another password to mess with)
4. In your C code
This means that only root or the special user you have for the job can see the files. Be sure permissions are set correctly on your executable.
It is not hacker-proof by any means, but casual users will not be able to do much with. Be sure your .keepme and .data files are set correctly permissions-wise. There is no error checking in the code, it needs some.
