Oct 30, 2016 at 18:29 comment added Schwern @uoɥʇʎPʎzɐɹC Asymetric public-private key encryption wasn't invented until the 1970s. If they did have it in WWII, there were no portable computers to run it on.
Oct 30, 2016 at 17:00 comment added noɥʇʎԀʎzɐɹƆ why not a low-end RSA?
Oct 30, 2016 at 12:13 comment added Murch I recall that there were instances where Germans used Swabian dialects in a similar manner.
Oct 29, 2016 at 15:18 comment added Clay Nichols I just started watching WindTalkers (awful movie, great subject). I see now that the benefit was tactical, short range voice "encryption". I always thought it was because it couldn't be decrypted (and wondered why not). Thanks! GREAT answer.

Add information about the written Navajo language.
Oct 26, 2016 at 17:41 comment added T.E.D. @SVilcans - Indeed the Japanese were eventually aware what language was being used, and even managed to capture a Navajo and order him under pain of torture to decode the messages. He was unable to do so, because even though he spoke the language, he did not know the code.
Oct 26, 2016 at 12:19 comment added MichaelChirico worth mentioning that the Americans weren't alone in such obfuscation efforts. As I recall the Japanese used Kagoshima-ben, an almost incognate dialect famously hard to grok even among the Japanese, to encrypt messages. Would be interesting to hear similar stories from others if they have them.

Oct 26, 2016 at 7:16 comment added liftarn Also keep in mind that the code talkers use a code based on their languages, but even if you understood the language as such the code would still be very hard to understand. For instance a tank may be called "turtle", a bomber called "pregnant airplane" and a machine gun called "sewing machine". Also see en.wikipedia.org/wiki/Code_talker
