Data Encryption is often widely used tool to provide security features. It translates the clear text into code such that it can only be accessed with the person who has the appropriate key. The recovery of clear text from such an unscrambled data is deciphering. Enciphering can be implemented by using some substitution technique, shifting technique or even mathematical logics. Application of such types of techniques is difficult to retrieve clear text. In the bygone times, several symmetric key base algorithms have been developed. This paper enlightens and analyzes the substitution ciphers and transposition ciphers. With the comparison of different parameters used in the algorithms give significance of the algorithm.
