SearchAllSoft.com - BigSpeed Peer-to-Peer SDK 2.0

BigSpeed Peer-to-Peer SDK is a coiffe of two COM components (Agent and Hub) that lets you coiffe up a virtual private peer-to-peer (P2P) network for procure file sharing and messaging. The transfered data are scrambled using on-the-fly 128-bit AES encryption, without need of SSL certificates. NAT traversal is implemented by using TCP hole-punching technology. The security is provided in two different modes: symmetric encryption with shared mystic key and asymmetric encryption with 1024-bit public / private keys. The hub is responsible for keeping information on and authentication of online peers. All peers connected to a item hub soma a single private community. Each agent acts as both a client and a server at the same time. Fine grained access control is realized by a user-oriented permissions. They grant access control privileges to organisation resources and services in a elastic and procure manner. Two different openhearted of moment information bottom be exchanged between peers: alert and schmoose messages. In accession to stock FTP operations, such as upload, download, rename, delete, etc., the SDK also offers several advanced features. The broken file transfers are resumed automatically (if enabled), with MD5 integrity checking. The agent is able to ladder search operation on the peers. The server module is able to perform file contraction and decompression by a request from the remote client module. There is an option to compact on-the-fly the outgoing data before encrypting, which may slenderize greatly the transfer time for big files. BigSpeed Peer-to-Peer SDK utilizes an elegant event-driven paradigm for slowly integration into Windows applications. A special attention is paid to allow responsive user interface while avoiding multithreading problems and maintaining maximum bandwidth efficiency. Sample applications are included in VB .NET, VB 2005 and Delphi 7.
