Examples

  • A lot of material: photostats, diagrammatic printouts, two sets of holocryptic gammas with red and black pages printed on nitrated cellulose, KGB/GRU Monome-Dinome tables with complete matrices and side and top co-ordinates, so forth.

    The Sinkiang Executive

  • The March number explains an ingenious holocryptic cipher, written with the English alphabet, with no more letters than would be required for ordinary writing, yet so curiously complicated, that, while with the key easy to understand, it is without the key absolutely undecipherible, even to the inventor of the plan; and the key is capable of so many variations, that every pair of correspondents in Christendom may have their own cipher practically different from all others.
