It is interesting to have an iPhone, iPad and MACBook..
Messages are delivered to all three not exactly simultaneously.

This requires at least four keys or access to the shared key.   It is
interesting to see "new  device using your ID" messages after updates.
  I always keep an old iPhone alive as I can do many WiFi &
saved-to-device things (podcases- music) with it and not burn phone
service batteries, good for air travel..

Code books and pre-shared keywords  as in "Tora Tora Tora"  editors
can expand TTT to "Tora Tora Tora"
as can other simple transformations/translations.   programmers can
include homecode.h and
run  a message through sed and cpp.

The sloppy users will get caught.
