Navajo.
However if you mean the Navajo Code Talkers, they spoke in a code composed of Navajo words and phrases using a memorized "code book" with both a set of code words and phrases for common military terms, etc. as well as a substitution cypher of words for english letters and digits to send information not in the code. As the system was all memorized if the "code book" had to be destroyed to prevent capture it meant killing the Code Talker.
Ordinary Navajos recognized the words but could not understand the coded message.
