Abstract

With the day-by-day advancement of the Internet throughout the world, online marketing sites and applications are growing rapidly. More and more social networking sites are emerging almost every day connecting people from various parts of the world. These situations demand the organizers behind those networks to generate and store a huge amount of data regularly. Nonetheless to say, the more the data, the more is the risk of losing it. Hackers, phishers, or breachers are there at every nook and corner of the World Wide Web to steal and abuse the data of users. To protect the data from breaches, it is a necessity to secure the network. The general method of network protection is known as "Cryptography". Users are generally given a unique User ID and authentication code known as Password under which their data are stored individually. In this paper, we will discuss the overall idea of cryptography along with its methods and techniques.
