What is a cipher code?
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.
Codes generally substitute different length strings of character in the output, while ciphers generally substitute the same number of characters as are input..
Why couldn’t the Japanese break the Navajo code?
Without a willing Navajo to work with, progress on the code-breaking project was stalled for a long time. The difficult consonants, vowels, and the tonal structure made it impossible for most untrained people to even transcribe. The Japanese had been good at breaking every code before that.

How are most codes cracked?
Most codes using a relatively simple substitution method are most easily cracked by doing a simple plug-and-chug, figuring out the letters one by one and patiently figuring out the code based on guesses.
What is a code 4?
Code 4 Meaning “Code 4” means everything is under control or the scene is safe.? It indicates the officers are now in charge of the situation they were called to. For us it means when Code 4 is working we make sure everyone is safe and we are in control.
Are there any code talkers still alive?
Only one veteran Navajo code talker remains of the original 29 Navajo Marines who used their native language to devise an unbreakable code during World War II. Growing up in New Mexico, Chester Nez and many of his fellow Navajo were punished for speaking their language.
Is there an unbreakable cipher?
The only unbreakable cryptosystem known – the Vernam cipher. Of all the methods of encryption ever devised, only one has been mathematically proved to be completely secure. It is called the Vernam cipher or one-time pad. The worth of all other ciphers is based on computational security.
What is an unbreakable code?
The Unbreakable Code Code Talkers used native languages to send military messages before World War II. Choctaw, for example, was used during World War I. The Marine Corps, however, needed an “unbreakable” code for its island-hopping campaign in the Pacific.
