Very cool to read all the details beyond the one-time-pad records described in Cryptonomicon!

Solitaire Cyphers are the one that stuck with me from Cryptonomicon. iirc, there's supposed to be enough combinations in a shuffled deck of cards that every time anyone shuffles a deck, it should be a unique ordering.

This technology (SIGSALY) also features in Cryptonomicon.

Lawrence Waterhouse uses it while he stationed in Brisbane to talk chat to Turing on the other other side of the planet.

It is not a major plot device, but it is used.
