             interestingly wikimierda has this bit
             [3]https://en.wikipedia.org/wiki/One-time_pad
             "First described by Frank Miller in 1882,[4][5] the one-time
     pad was re-invented in 1917. On July 22, 1919, U.S. Patent 1,310,719
     was issued to Gilbert Vernam for the XOR operation used for the
     encryption of a one-time pad"
             So...the technique is older than 1940s...

   Yeah the OTP is the most well-known highly strong cryptographic thingy,
   like quartz in geochemostry.
   I heard people recently talking about using _multiple_ OTP's.  Not sure
   how that helps anything but it sounds nice and paranoid.
   I don't know the cryptography, but I can observe that the xor operation
   has half as many output states as input states, and that each one is
   evenly dependent on both input states, so if half your input state is
   both fully secret and fully random for every bit, the output state is
   fully random for every bit too and contains no information on the
   public input state (but I have delusions, so check with a crypto
   mailing list or something).
