The process of securing the data in communication from source to receiver is called cryptography. In theprocess of cryptography, we use a key and an algorithm. The key influences the security of the data partially. Also, thealgorithm influences the security partially. In cryptography, the size of the key is limited due to human memorability. It isimpossible to design the key by knowing its dimensions. A modified and advanced approach is proposed in this paper forincreasing the security of the data. We are concentrating the key part of the cryptography as well as the input image forincreasing the security of the data. We use the 2Dimensional graphic image designed by the user which composed of pixels inwhich every pixel have same or different ASCII value. In the proposed algorithm, we will generate a key of any size which isused in encryption as well as in decryption.
