Research on a Normal File Encryption and Decryption.pdf

1、The advent of information technology (internet) some decades ago has brought about manychanges in the way information is being disseminated and exchanged between people, betweennations and as well in the whole world. Lon

2、g ago, the issue of information "theft" has evolvedworldwide and concerns about how to remediate it are getting the attention of experts in thearea of Information Security. Today, with the current proliferation of some

3、newly inventedmethods in cryptanalysis it is obvious that information security is the panacea. In this paper we present a review of papers which deal about information security with afundamental aim of curing the iss

4、ue of safety of information storing in files or other means ofstorage. Hence the idea of the Research on a Normal File Encryption and Decryption using AESand MD5. As a matter of fact our paper focuses on the entire p

5、rocedure or process of how a file ofany kind is encrypted and decrypted through the use of the application presented in this work. In the process of describing the file encryption procedure, we used a HHEA algorithm

7、tion have shown that the method used is reliable because of thestrength of the algorithm enables a safe and protected message when the key is delivered to theintended receiver. Throughout this research work emphasis
