And now I'll take the secret, base64 it, add a space between each character, reverse the order and base64 it again. And then toss it through a round of AES256 with my key, all before echoing it.

Trying to prevent people from exfiltrating data by filtering the output stream is an impossible battle.

It wouldn't stop outright, and I tried to communicate that I knew it wouldn't in my comment. It would make it so if someone got caught doing that, it would be harder for them to deny that they did it deliberately, and you could throw the book at them. As it is now, they could print it out and say that they were just debugging, or they could even think it was permissible to print it out.

I can see the point of removing plausible deniability - it's just that I'm of the opinion that if something is known to be insecure it shouldn't try to pretend otherwise.
