    cryptography is a study of message secrecy....particularly in the techniques used in  computer and network security for such things as access control and information confidentiality.Cryptography is also used in many applications encountered in everyday life; examples include security of ATMcards computer password  all depend on cryptography.

    Cryptography (or cryptology; derived from Greek κρυπτός kryptós "hidden," and the verb γράφω gráfo "write") is the study of message secrecy. In modern times, it has become a branch of information theory, as the mathematical study of information and especially its transmission from place to place. The noted cryptographer Ron Rivest has observed that "cryptography is about communication in the presence of adversaries", which neatly captures one of its unique aspects as a branch of engineering, and differences from, for instance, pure mathematics. It is a central part of several fields: information security and related issues, particularly, authentication, and access control. One of cryptography's primary purposes is hiding the meaning of messages, but not usually their existence. Cryptography also contributes to computer science, particularly in the techniques used in computer and network security for such things as access control and information confidentiality. Cryptography is also used in many applications encountered in everyday life; examples include security of ATM cards, computer passwords, and electronic commerce all depend on cryptography.

    Cryptography is used for security purposes !

    The term crypto refers to change. this involves encryption and decryption, also called enciphering and deciphering !

    For more details, chk out Wikipedia..
