Implementation Of Secured P2p Network (P2p File Transfer)

Downloading has become indispensible to use an application and to work with. Peer to Peer method of downloading allows users to quickly download a file from any of the peers but sometimes the data in peer gets corrupted and makes the user to download the corrupted/fake file and also it’s difficult for the corrupted peer to recover their file back. So in this paper we are using Secured Hash Algorithm-1(SHA-1) algorithm for validity test and to recover the corrupted data using a centralized server. Index Terms— Peer-to-Peer, SHA1, Centralized Server.
