In this paper, the authors have introduced a new advanced symmetric key cryptographic method called NJJSAA. The authors introduced new bit manipulation method for data encryption and decryption of any file. Nath et al already developed some symmetric key methods where they have used some randomized key matrix for encryption and decryption methods. In this paper, the authors have used a bit manipulation method which include bit exchange, right shift and XOR operation on the incoming bits.
