In this paper, a new hybrid concept is proposed by analyzing the principle of the hybrid cryptography based on the combination of symmetric and message digesting. Moreover, the security and performance of the proposed concept will also estimate. In proposed concept the authors designed a new symmetric encryption algorithm and combine with SHA-1 message digesting function to provide hybrid nature. Now the proposed system will try to improve exiting problem. In proposed system symmetric key will use series of logical functions like XOR, Circular Shift (Right, Left), Feastel function and these operations are time efficient operation as compared to mathematical operation for providing confidentiality and authentication.
