Encryption is the process of transforming information using an algorithm to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information. The reverse process, i.e., to make the encrypted information readable again, is referred to as decryption. There are many techniques for this encryption and decryption of messages. This paper introduces the users with all the existing techniques of encryption and decryption and the proposed paper.
