In Recent times, we are facing various challenges in security related issues during data transfers. There are various security models following different enciphering techniques for the betterment of secured data transfer. Though there exist many complex cryptographic encryption algorithms, which provide high level of security, vulnerability of those algorithms increases day after a day. It is to be worth saying a point that modification of existing complex algorithms will obviously intensifies to the enhancement in security of algorithm as well as the data ,provided the modification should not be eavesdropped easily than the original algorithm. In this paper, we proposed a software tool which considerably enhances the security by following an iterative approach depending upon sender's need. Our experiments show that the use of iterative approach enhances the security provided by the algorithm when compared to the non-iterative approach.
