Free SSL and Automatic HTTPS for node.js with hapi.js and other middleware systems via Let's Encrypt

* Automatic Registration via SNI (`httpsOptions.SNICallback`)
  * **registrations** require an **approval callback** in *production*
* Automatic Renewal (around 80 days)
  * **renewals** are *fully automatic* and happen in the *background*, with **no downtime**
* Automatic vhost / virtual hosting

All you have to do is start the webserver and then visit it at it's domain name.

## Install

```
npm install --save greenlock-express@2.x
```

*Pay no attention to the man behind the curtain.* (just ignore that the name of the module is greenlock-express)

### Part 1: Configure Greenlock

```javascript
'use strict';

var le = require('greenlock-express').create({
  server: 'staging' // in production use https://acme-v01.api.letsencrypt.org/directory
  
, configDir: require('os').homedir() + '/letsencrypt/etc'
  
, approveDomains: function (opts, certs, cb) {
    opts.domains = certs && certs.altnames || opts.domains;
    opts.email = 'john.doe@example.com' // CHANGE ME
    opts.agreeTos = true;
    
    cb(null, { options: opts, certs: certs });
  }
  
 , debug: true
});
```

WARNING: If you don't do any checks and simply complete `approveDomains` callback,
an attacker will spoof SNI packets with bad hostnames and that will cause you to be rate-limited
and/or blocked from the ACME server.
Alternatively, You can run registration *manually*:

```bash
npm install -g greenlock-cli

greenlock certonly --standalone \
  --server 'https://acme-v01.api.letsencrypt.org/directory' \
  --config-dir ~/letsencrypt/etc \
  --agree-tos --domains example.com --email user@example.com

# Note: the '--webrootPath' option is also available if you don't want to shut down your webserver to get the cert.
```

### Part 2: Just add Hapi

```javascript
var hapi = require('hapi');
var https = require('spdy');
var server = new hapi.Server();
var acmeResponder = le.middleware();
var httpsServer = https.createServer(le.httpsOptions).listen(443);

server.connection({ listener: httpsServer, autoListen: false, tls: true });

server.route({
  method: 'GET'
, path: '/.well-known/acme-challenge'
, handler: function (request, reply) {
    var req = request.raw.req;
    var res = request.raw.res;

    reply.close(false);
    acmeResponder(req, res);
  }
});

server.route({
  method: 'GET'
, path: '/'
, handler: function (request, reply) {
    reply("Hello, I'm so Hapi!");
  }
});
```

### Part 3: Redirect http to https

```javascript
var http = require('http');
var redirectHttps = require('redirect-https')();

http.createServer(le.middleware(redirectHttps)).listen(80, function () {
  console.log('handle ACME http-01 challenge and redirect to https');
});
```
