Just encrypt the file using an algorithm that is available on all of the platforms you need to support.

Then you still run into the question "But where do I store the key to decrypt that file?"

You cannot stop a determined hacker. You can, however, help to keep honest people honest.

An alternative is to "sign" the password file. If it is changed, it will no longer match the signature.
