Data sharing through the networks becomes an important aspect in today's computing scenario. The main advantage of networks is fast transmission of data, at the same time the disadvantage is the security threats. This paper describes about the cryptography for ensuring data confidentiality and also discusses about substitution cipher. Cryptanalysis is done with an example data to show how the encipherment algorithms are broken which will help the researchers to develop more secured encipherment algorithms.
