Encryption has been around since Roman times, and probably long before that. Even if not, bear in mind most military leaders then had people from their own lands in their ranks so it would be easy to find a trusted person to deliver the message.

Surely the first person to obscure their meaning in any way engaged in the first form of encryption? Regardless even of whether someone could decrypt their meaning.
