Thanks. But large encrypted messages on monuments doesn’t work for immediate comms. But I get your gist.
Aye, it’s the gist I was getting at.
The point to the Kryptos monument is- even the CIA haven’t cracked it yet in almost 20 years and they REALLY want to.
What you’re after is do-able, completely do-able. You apply something similar to text in real time and there would be no way for them to crack it in a reasonable enough time.
Now, how to go about that- I don’t know. I’m not a tech kind of guy. Not too much help there I guess :-\ It just doesn’t seem like it ought to be that hard to do what you’re talking about.
