BigSpeed Peer-to-Peer SDK is a set of two COM components (Agent and Hub) that lets you set up a virtual private peer-to-peer (P2P) network for secure 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 secret key and asymmetric encryption with 1024-bit public/private keys.
