The mathematical science used to secure the confidentiality, integrity, authentication, and non-repudiation of messages by use of codes, ciphers and cryptograms. Also the act or art of writing in codes or ciphers. It is the pursuit of four particular goals:

__Confidentiality__ :
    The message can only be understood by the designated recipient.
__Integrity__ :
    No undetected alteration of the message in transit or storage is possible.
__Authentication__ :
    The sender and the recipient of the message can verify each other's identity.
__Non-repudiation__ :
    The sender cannot disclaim his/her intentions in the creation or transmission of the message.

Procedures and protocols used to achieve (some of) these goals are known as cryptosystems.

[Cryptography] is divided largely into ConventionalCryptography and PublicKey cryptography.
