There are a lot of posts looking for ways to encrypt the source code both to prevent reverse engineering and to prevent ripping of passwords etc.
To encrypt, command line parameters could be used. Something similar to KixStrip but with built-in encryption.
Decryption should be on-the-fly in memory. As a safeguard, Kix could check to see if it is called from a logon.
Give a man a fish and he will be back for more. Slap him with a fish and he will go away forever.
