Description
 
Secrets or Making and Breaking Codes is a practical field manual designed to teach the basic mechanics of enciphering and deciphering communications.
This is the only hands on guide to both the simplest cipher schemes which need little more than scratch paper and a pencil to crack-- as well as more sophisticated codes that use one time code books, pocket calculators, and most advanced computer based systems used by the military and diplomatic corps of most governments.
