The theme of this research work is to design and develop a very strong cryptographic technique which willbe used to provide the security for the alphanumeric characters, special characters and number when we transmit overthe network. However, this cryptographic technique very well addresses the problems that were faced by the classicalplay fair and 3D Play fair technique is used in the present study. In this paper, an enhanced approach has been done toovercome the problem in existing traditional playfair technique. In this work, there are 4 characters used at the sametime and make them as a pair and then it will be considered them for the encryption. As we had the problem in theclassical play like using i and j as same character here we eliminate this problem and then we also eliminate the problemof 3D play fair which will use only certain limited character sets for encryption and that is not case sensitive. But in ourproposed method, we have taken into consideration of all the 256 ASCII characters for encryption and are also verycomplex algorithm when compared to previous replacement techniques.
