In its simplest term, a [[Code|code]]s are, in their simplest terms, replacing words and phrases in is the replacement of a [[Plaintext|message ]] with other words and phrases an [[Ciphertext|alternative message]] whose meaning is known to the recipient. For example:
Take the phrase: "The bombers require a fighter escort at Newcastle, 2300 hours"
There are many ways to encode this. Some appropriate rules must be created For example, both the sender and shared with the recipient. Because could agree on appropriate rules to anyone who intercepts the encode that message. Ideally, something that sounds like these rules would create a code could [[Ciphertext|ciphertext]] that would not arouse their the suspicionsof an intruder intercepting the message. Otherwise, causing the message to could be decoded, destroyed, or otherwise delayed. "cracked" (decoded) or to be destroyed or otherwise delayed. Therefore it is wise to create a code that produces innocent sounding messages:
