However, this exact form of encoding was used as a form of encryption while the US was at war; the Navajo Code Talkers.

Somewhat off topic, of course, but a great example of how encryption and encoding can have identical end results.

You can record an encrypted message and get it decrypted by anyone who demonstrates knowledge of the key. The process is identical to finding someone who demonstrates knowledge of Haitian. Encryption is nothing more than an uncommon encoding.
