Encryption provides a means where information is secured. With more information stored in computers and send via computer networks, the need to ensuring that the information is not vulnerable to snooping or tampering becomes quite relevant. With this fast progression towards the digital form of data exchange especially in digital media, Information security is thus becoming more significant in transmission and storage of data. Information confidentiality being a prominent significance in research and study of law, ethics and information systems. With the evolution of the human form of intelligence, the art of cryptography has hence become complex as a way of making information more secure. Encryption systems arrays are being the deployed mostly into the world of by various Information systems agencies [1]. Cryptography is such an integral aspect of a modern world of informatics unintelligible to any unauthorized people. There are many algorithms with such cost-performance tradeoff. Thus, among this cryptographic algorithm, we choose one which bests suits the end user requirements. The study of Algorithms weaknesses, strengths and performance will provide much-needed insights. In this paper, we will analyze in details performance visa -vis cost of popular cryptographic algorithms as 3DES, RSA, DES and AES to ascertain their effectiveness in data security.
