Abstract

This application provides security at file content level. It uses Cryptosystems which are highly technical systems that provide privacy through secret encoding using Rijndael algorithm which has been an important part of the electronic information transfer. This cryptosystem protects data by using hardware and software renovation in a process that protects data by performing mathematical operations/algorithms on it. The result cipher text can be even then transmitted over insecure lines or through wider networks. If this cipher text is intercepted by hackers, it is indecipherable and meaningless to him on to the strong rounds of Rijndael cipher active algorithm. When the cipher text reaches its final destination, it can be decrypted into the original state of the data only by the authentic
users.
