Where does the word cryptography come from?
The word “cryptography” is taken from the Greek word “kryptos” meaning hidden and graphein meaning writing. Cryptography is the science of hidden writing or more accurately the study of encrypting or encyphering messages so that their content is obscured until they are decrypted or decyphered. Typically, the encryption process uses a key or password, the encryption key, and the message can only be decrypted if the correct decryption key is given.
