Cryptology
is the study of hidden writing. It comes from the Greek words Kryptos, meaning hidden, and Graphen, meaning to write. Cryptology is actually the study of codes and ciphers. Concealment messages aren't actually encoded or enciphered, they are just hidden. Invisible ink is a good example of a concealment message.
A code is a prearranged word, sentence, or paragraph replacement system. Foreign languages are just like secret code, where the English word "hi" is represented as the word "Hola" in Spanish, or some other word in another language. Most codes have a code book for encoding and decoding.
The name cipher originates from the Hebrew word "Saphar," meaning "to number." Most ciphers are systematic in nature, often making use of mathematical numbering techniques. One example of a cipher is the Spartan stick method.
