+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.
