BIGSPEED Peer-to-Peer SDK 3.0
igSpeed Peer-to-Peer SDK is a set of two COM components (Agent and Hub) thatnlets you set up a virtual private peer-to-peer (P2P) network for secure file sharing and messaging.nThe transfered data are scrambled using on-the-fly 128-bit AES encryption, without need of SSL certificates.nNAT traversal is implemented by using TCP hole-punching technology.nThe security is provided in two different modes: symmetric encryption with shared secret key andnasymmetric encryption with 1024-bit public/private keys.nnThe hub is responsible for keeping information on and authentication of online peers.nAll peers connected to a particular hub build a single private community.nnEach agent acts as both a client and a server at the same time.nFine grained access control is realized by a user-oriented permissions.nThey grant access control privileges to system resources and services in a flexible and secure manner.nnTwo different kind of instant information can be exchanged between peers: alert and chat messages.nnIn addition to standard FTP operations, such as upload, download, rename, delete, etc.,nthe SDK also offers several advanced features.nnThe broken file transfers are resumed automatically (if enabled), with MD5 integrity checking.nThe agent is able to run search operation on the peers. The server module is able to perform file compression and decompression by a request from the remote client module.nnThere is an option to compress on-the-fly the outgoing data before encrypting,nwhich may reduce greatly the transfer time for large files.nnBigSpeed Peer-to-Peer SDK utilizes an elegant event-driven paradigm for easy integration into Windows applications. A special attention is paid to provide responsive user interface while avoiding multithreading problems and maintaining maximum bandwidth efficiency.nnSample applications are included in VB .NET, VB 2005 and Delphi 7.
