Code Breaking. Cryptography. Cryptology. The word Cryptology comes from the Greek word kryptos, which means hidden and logos, which means word.
It is the branch of science that deals with secret communications. To keep communications secret, it is necessary to use a code, a cipher, or both. A code is a system of symbols representing letters, numbers or words. For example, you could create a code that might represent the following words as: The=01, in=02, Spain=03, mainly=04, rain=05, falls=06, Germany=07, drops=08, on=09, plain=10 The encoded message might read: When you decoded the message by replacing the number with the matching word you get: The rain in Spain falls mainly on the plain.
Without the table showing what words go with which numbers, it would be very hard to guess the meaning of the encoded message. Codes are not used only to protect secret information. The table that contains the translation of the words to the code is often in the form of a book and is referred to as a codebook. Ciphers Meet you at the corner. How Code Breakers Work.

Whether you're writing notes to your friends in class or trying to get into cryptography (the study of codes and ciphers) as a hobby, this article can help you learn some of the basics and get you on your way to encoding your own messages. Just see Step 1 below to get started! Some people use the words code and cipher to mean the same thing, but people who take these things seriously know they really mean two different things.

Tapped Code Gibberish Tips Warnings. Secret Language: Cryptography & Secret Codes. Ron Hipschman When you were a kid, did you have a "Captain Midnight" decoder ring?
With it, you could send messages to a friends that no one else could read. Or perhaps you remember using special symbols to write notes to your "squeeze" in class. If the note was intercepted , your teacher, could learn nothing about your romance. In more serious uses, codes and ciphers are used by our military and diplomatic forces to keep confidential information from unauthorized eyes. The study of enciphering and encoding (on the sending end), and deciphering and decoding (on the receiving end) is called cryptography from the Greek (kryptos), or hidden and (graphia), or writing. For a cipher to be useful, several things must be known at both the sending and receiving ends.
The algorithm or method used to encipher the original message (known as the plaintext).The key used with the algorithm to allow the plaintext to be both enciphered and deciphered.The period or time during which the key is valid. What is Cryptography?
