More nonsense - unbreakable means that you cannot determine what the
plaintext is. Shannon proved that you cannot prove what the plaintext
is for OTPs, or for the system we have developed either. The fact that it
could possibly be any plain text simply is another way of saying that it
is unbreakable, they are one and the same thing. Like so many you are
talking in circles and do not know what you are talking about or you
would not waste your time on such nonsense - Paul Bradley even knows how
to brute force OTPs, so you must be wrong there to.
