[noise] Noise Socket - live demo

[Alexey Ermishkin]

Meanwhile I've launched a small demo app located at
https://noise.virgilsecurity.com which represents the current draft spec.

It supports  XX, IK, padding & maximum size negotiation.

It listens to 3 NoiseSocket ports (13242-13244) each of which uses different
strategy for choosing incoming sub-messages.

13242 - server priority
13243 - random
13244 - first sub-message

To see it in action, there is a reverse proxy written in Go
https://github.com/go-noisesocket/noisesocket/tree/master/sample/reverseprox
y
It caches server public key, thus able to use IK for subsequent connections.


You can run proxy, point a browser to it (local ports 1080-1082) and see
that everything works.

Server tries to answer with error string if it is unable to process a
packet.

Hope it will help implementers to implement faster.
