Cryptography is an art of scrambling the data in order to provide security and confidentiality. Cryptography is being used in order for the securely transmission of the data. Now a day's it is impossible to provide security as the hacker or the attackers can easily get the data as they are easily able to know key and if key get key they will be able to decrypt the people whole important data. This paper survey many research papers about cryptography and various means to make cryptography more robust and propose a way in order to make the people encryption more reliable and secure by adding randomness to the key, by adding the randomness to the key in order to keep the important data more secure.
