Introduction
Cryptography is defined as the art or process of writing in or deciphering secret code: any system of secret writing. Encryption is used in electronic systems to achieve privacy and authentication of information. The privacy requires, two questions need to be answered: what are the consequences of unauthorized access to or disclosure of the valuable information, and how often the possibility of unauthorized access to or disclosure of information. Authentication addresses the issues of whether data is from the correct source or if it has been unauthorized with. Functions embedded with in cryptographic systems help ensure data integrity by guaranteeing authenticity of a message and allowing the use of digital signature, a data block attached to a message that binds the message to a sender so that it can be verified by the receiver or others.

A cryptographic system performs transformations that encrypt or decrypt information along with one or more keys that parameterize the transformations. The encryption function changes original data into unintelligible data, while the decryption function performs the reverse function, that is Cipher text is reversed back into normal text. Keys is of two types: non-rigid or rigid. Those that are not rigid allow the same encryption and decryption functions to be used with various keys and
