sni

Get the Server Name Indication of a raw TLS stream (without Node's TLS module)

Installation

npm install sni

Usage

var sni = require("sni")
  , net = require("net");

net.createServer(function(socket) {
    socket.once("data", function(data) { // Listen on the HELLO packet
        console.log(sni(data)); // www.example.com
    });
}).listen(443); // Listen on the HTTPS port

Benchmark

1,000,000 rounds took me 3,524 ms. Test it for yourself with test/benchmark.js.

Why?

Because I wanted to route my HTTPS streams without actually encoding them with Node's TLS module.
