摘要：On considering the current scenario, Most of the existing systems which offer security to a network or web or to a data are vulnerable to attacks and they are breached at some point of time by effective cryptanalysis, irrespective of its complex algorithmic design. In general, today�s crypto world is restricted to a practice of following any one single encryption scheme and that too for a single iteration on a single file basis. This is evident in the 99% of the encryption-decryption cases. So, A need for �practically strong and infeasible to get attacked� technique becomes vital. In this paper, we propose a Software tool which involves Cryptographic enciphering and deciphering along with File Splitting and Merging mechanisms. We used modified Blowfish algorithm for Encryption and Decryption of data. Though we use only one algorithm, we differentiate the cryptographic scheme by varying the key for varying file slices. Our results clearly justifies that our tool serves as a better solution both in terms of performance as well as security.
