Bigspeed Secure Socket Library

"The evolution of TCP for private use"

Version 3.0
Idea
We want to find a way to build private networking applications easily. Our peers will be grouped logically in a virtual community of trusted nodes. A simple and efficient method must secure our communications without using third-party certificate authorities. A single connection should be used for all transferred data, which will be organized in named packets with additional headers.
