ABSTRACT
Cryptography is derived from a Greek word which means hidden secret and is practiced to secure the data from third party. More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, and authentication. The ancient cryptography just meant the encryption of the data while the Modern cryptography follows a strongly scientific approach, and designs cryptographic algorithms around computational hardness assumptions, making such algorithms hard to break by an adversary. Due to modernization the world has moved on towards various technologies that uses computers.In order to prevent some unwanted users or people to get access to the data cryptography is needed.
