The Navajo code is made of a dictionary that contains words of English military vocabulary, and words that translate letters. Encryption is a substitution of words or characters of a text in the Navajo dialect.
Some letters have several translations in Najavo code, dCode selects one at random.
In practice dCode limited to the substitution of alphabetic characters, English vocabulary is not treated.
Example: FRANCE can be translated directly with DA-GHA-HI but FRANCE can also be translated letter by letter F,R,A,N,C,E : TSA-E-DONIN-EE, DAH-NES-TSA, BE-LA-SANA, TSAH BA-GOSHI, DZEH
Do not confuse the Navajo language (used by the navajo people) with the Navajo code (used by the US military, described on this page)
Decryption consists in identifying words of in Navajo language and translate then. In practice dCode search if vocabulary words are included in the message, then tries letters.
Example: NA-NIL-IN means confidential
Example: US-DZOH means dash (in English) and is converted to - (punctuation)
The Navajo language uses hyphens, if the message does not contain any, dCode will try to correctly find them in Navajo (with a hyphen), but the outcome is not perfect.
Example: LHA-CHA-EH BA-GOSHI NE-AHS-JAH CHINDI AH-NAH is translated by DCODE
The ciphered message is composed of characteristic sounds such as TSA, DAH, DZEH.
Any reference to the Native American Navajo tribe is a clue.
The Navajo code was originally an Indian tribe language only spoken. Unlike any other language, the verb does not relay on the subject but also with the genitive. This dialect is extremely complex. In 1942, only 28 Americans understand it and speak it. It will be used by the Americans during the war against the Japanese. This is one of the few codes of history that will never be cracked.
The language is very old, but the code has been set during World War II.
