Just for fun. If no one's listening nothing happens, if someone is and knows how to decrypt AES256 and similar, they'll be WTFied.

Or take it to an extreme as was proposed by Ron Rivest when the US was considering making all unauthorized encryption illegal:

Problem is the exchange of the random data :) If you exchange a 16TB drive filled with random data with your counterpart you wish to talk with, you are safe to send 16TB. After that it gets tricky :)

That is the good old OTP (= "one time pad" encryption). IMHO the only unbreakable encryption. I would consider all encryption methods (public or not) and most "computer stuff", including all types of operating systems, to be backdoored or easily attackable.
Just think of what 50000 of very clever NSA employees (what little info is known, they reach only out for *very* clever people) could create or break, while working full time on it. Then add the same sort and number of People for Russia, for China and again for the rest of the world...

Unbreakable to the limit of human error. Look up the Venona decrypts, which were largely enabled by Soviet operators misusing one time pads. Key word is "one time"...if this principle is violated all bets are off when facing a nation state adversary.

It was not a problem of the operators.. Soviets printed out several identical copies of the one time pads booklets.. Because of being in hurry during Nazi invasion.

A one time pad used twice isn't a one time pad. It's literally in the name.
