## HTTPS

HTTPS is the HTTP protocol over TLS/SSL. In Node this is implemented as a
separate module.

## https.Server

This class is a subclass of `tls.Server` and emits events same as
`http.Server`. See `http.Server` for more information.

## https.createServer(options, [requestListener])

Returns a new HTTPS web server object. The `options` is similer to
`tls.createServer()`. The `requestListener` is a function which is
automatically added to the `'request'` event.

Example:

    // curl -k https://localhost:8000/
    var https = require('https');
    var fs = require('fs');

    var options = {
      key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
      cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
    };

    https.createServer(options, function (req, res) {
      res.writeHead(200);
      res.end("hello world\n");
    }).listen(8000);


## https.request(options, callback)

Makes a request to a secure web server.
Similar options to `http.request()`.

Example:

    var https = require('https');

    var options = {
      host: 'encrypted.google.com',
      port: 443,
      path: '/',
      method: 'GET'
    };

    var req = https.request(options, function(res) {
      console.log("statusCode: ", res.statusCode);
      console.log("headers: ", res.headers);

      res.on('data', function(d) {
        process.stdout.write(d);
      });
    });
    req.end();

    req.on('error', function(e) {
      console.error(e);
    });

The options argument has the following options

- host: IP or domain of host to make request to. Defaults to `'localhost'`.
- port: port of host to request to. Defaults to 443.
- path: Path to request. Default `'/'`.
- method: HTTP request method. Default `'GET'`.

The following options can also be specified.
However, a global [Agent](http.html#http.Agent) cannot be used. 

- key: Private key to use for SSL. Default `null`.
- cert: Public x509 certificate to use. Default `null`.
- ca: An authority certificate or array of authority certificates to check
  the remote host against.

In order to specify these options, use a custom `Agent`.

Example:

    var options = {
      host: 'encrypted.google.com',
      port: 443,
      path: '/',
      method: 'GET',
      key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
      cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
    };
    options.agent = new https.Agent(options);

    var req = https.request(options, function(res) {
      ...
    }

Or does not use an `Agent`.

Example:

    var options = {
      host: 'encrypted.google.com',
      port: 443,
      path: '/',
      method: 'GET',
      key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
      cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem'),
      agent: false
    };

    var req = https.request(options, function(res) {
      ...
    }

## https.get(options, callback)

Like `http.get()` but for HTTPS.

Example:

    var https = require('https');

    https.get({ host: 'encrypted.google.com', path: '/' }, function(res) {
      console.log("statusCode: ", res.statusCode);
      console.log("headers: ", res.headers);

      res.on('data', function(d) {
        process.stdout.write(d);
      });

    }).on('error', function(e) {
      console.error(e);
    });
