WebDec 3, 2001 · Cryptography is the study of encoding and decoding secret messages. In the language of cryptography, codes are called the ciphers, uncoded messages are called plaintext, and coded messages are called ciphertext. Cryptography has for long been an important issue in the realm of computers. WebWhat the Enigma machine was used for is called cryptology.This is the process of encoding (cryptography) and decoding (cryptoanalysis) information or messages (called plaintext).All of these processes combined are cryptology.
