The principle of bivalence merely states that every proposition is either true
or false. "Tertium non datur" is the law of the excluded middle, which is
not the same. Furthermore, neither one says anything about half the
population falling on one side or the other; you're either making that up or
confusing it with something else.

And, in fact, I have not done that, so you're constructing a strawman.

Hey, you're the one who argued that it's 2^384 to break. Even PHK's own paper
on GBDE puts the effort to break it at 2^129. Who is it that hasn't read the

And yet more nonsense. PKZIP isn't even a disk encryption system. And you
know very well that CGD and Loop-AES both predate GBDE. Claiming that there
is "nothing like it" is objectively false.
Now, if you'd care to stop making ad hominem attacks, perhaps there can be
some useful discussion.
