BigSpeed Secure Socket Library

 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.
