In today's world, information sharing and transfer has increased exponentially. Transmission of information may be vulnerable to security. For the proper security, the concept of cryptography came into scenario. Cryptography is helpful for ensuring that data is prevented against penetrations and to prevent espionage. It maintains the confidentiality of the data and also ensures that the contents of the data are confidential and should not be altered by any means. This paper mainly focuses on the concepts of Steganography and Preety Good Privacy (PGP).
