  Cryptography \Cryp*tog"ra*phy\ (-f?), n. [Cf. F. cryptographie.]
     1. The act or art of writing in code or secret characters;
        also, secret characters, codes or ciphers, or messages
        written in a secret code.
        [1913 Webster +PJC]
  
     2. The science which studies methods for encoding messages so
        that they can be read only by a person who knows the
        secret information required for decoding, called the key;
        it includes cryptanalysis, the science of decoding
        encrypted messages without possessing the proper key, and
        has several other branches; see for example
        steganography.
        [PJC]

  cryptography
       
           The practise and study of encryption and
          decryption - encoding data so that it can only be decoded by
          specific individuals.  A system for encrypting and decrypting
          data is a cryptosystem.  These usually involve an algorithm
          for combining the original data ("{plaintext") with one or
          more "keys" - numbers or strings of characters known only to
          the sender and/or recipient.  The resulting output is known as
          "{ciphertext".
       
          The security of a cryptosystem usually depends on the secrecy
          of (some of) the keys rather than with the supposed secrecy of
          the algorithm.  A strong cryptosystem has a large range of
          possible keys so that it is not possible to just try all
          possible keys (a "{brute force" approach).  A strong
          cryptosystem will produce ciphertext which appears random to
          all standard statistical tests.  A strong cryptosystem will
          resist all known previous methods for breaking codes
          ("{cryptanalysis").
