+[![Build Status](https://secure.travis-ci.org/mhart/aws4.png?branch=master)](http://travis-ci.org/mhart/aws4)
+
+A small utility to sign vanilla node.js http(s) request options using Amazon's
+[AWS Signature Version 4](http://docs.amazonwebservices.com/general/latest/gr/signature-version-4.html).
+
+Can also be used [in the browser](./browser).

+
+Indeed, the only AWS services that *don't* support v4 as of 2014-12-30 are
+[Import/Export](http://docs.aws.amazon.com/AWSImportExport/latest/DG/api-reference.html) and
+[SimpleDB](http://docs.aws.amazon.com/AmazonSimpleDB/latest/DeveloperGuide/SDB_API.html)
+(they only support [AWS Signature Version 2](https://github.com/mhart/aws2)).
+
+It also provides defaults for a number of core AWS headers and
+request parameters, making it very easy to query AWS services, or
+build out a fully-featured AWS library.
+
+Example
+-------
+
+```javascript
+var http  = require('http'),
+    https = require('https'),
+    aws4  = require('aws4')
+
+// given an options object you could pass to http.request
+var opts = {host: 'sqs.us-east-1.amazonaws.com', path: '/?Action=ListQueues'}
+
+// alternatively (as aws4 can infer the host):
+opts = {service: 'sqs', region: 'us-east-1', path: '/?Action=ListQueues'}
+
+// alternatively (as us-east-1 is default):
+opts = {service: 'sqs', path: '/?Action=ListQueues'}
+
+aws4.sign(opts) // assumes AWS credentials are available in process.env
+
+console.log(opts)
+/*
+{
+  host: 'sqs.us-east-1.amazonaws.com',
+  path: '/?Action=ListQueues',
+  headers: {
+    Host: 'sqs.us-east-1.amazonaws.com',
+    'X-Amz-Date': '20121226T061030Z',
+    Authorization: 'AWS4-HMAC-SHA256 Credential=ABCDEF/20121226/us-east-1/sqs/aws4_request, ...'
+  }
+}
+*/
+
+// we can now use this to query AWS using the standard node.js http API
+http.request(opts, function(res) { res.pipe(process.stdout) }).end()
+/*
+<?xml version="1.0"?>
+<ListQueuesResponse xmlns="http://queue.amazonaws.com/doc/2012-11-05/">
+...
+*/
+```
+
+More options
+------------
+
+```javascript
+// you can also pass AWS credentials in explicitly (otherwise taken from process.env)
+aws4.sign(opts, {accessKeyId: '', secretAccessKey: ''})
+
+// can also add the signature to query strings
+aws4.sign({service: 's3', path: '/my-bucket?X-Amz-Expires=12345', signQuery: true})
+
+// create a utility function to pipe to stdout (with https this time)
+function request(o) { https.request(o, function(res) { res.pipe(process.stdout) }).end(o.body || '') }
+
+// aws4 can infer the HTTP method if a body is passed in
+// method will be POST and Content-Type: 'application/x-www-form-urlencoded; charset=utf-8'
+request(aws4.sign({service: 'iam', body: 'Action=ListGroups&Version=2010-05-08'}))

+
+API
+---
+
+### aws4.sign(requestOptions, [credentials])
+
+This calculates and populates the `Authorization` header of
+`requestOptions`, and any other necessary AWS headers and/or request
+options. Returns `requestOptions` as a convenience for chaining.
+
+`requestOptions` is an object holding the same options that the node.js
+[http.request](http://nodejs.org/docs/latest/api/http.html#http_http_request_options_callback)
+function takes.
+
+The following properties of `requestOptions` are used in the signing or
+populated if they don't already exist:
+
+- `hostname` or `host` (will be determined from `service` and `region` if not given)
+- `method` (will use `'GET'` if not given or `'POST'` if there is a `body`)
+- `path` (will use `'/'` if not given)
+- `body` (will use `''` if not given)
+- `service` (will be calculated from `hostname` or `host` if not given)
+- `region` (will be calculated from `hostname` or `host` or use `'us-east-1'` if not given)
+- `headers['Host']` (will use `hostname` or `host` or be calculated if not given)
+- `headers['Content-Type']` (will use `'application/x-www-form-urlencoded; charset=utf-8'`
+  if not given and there is a `body`)
+- `headers['Date']` (used to calculate the signature date if given, otherwise `new Date` is used)
+
+Your AWS credentials (which can be found in your
+[AWS console](https://portal.aws.amazon.com/gp/aws/securityCredentials))
+can be specified in one of two ways:
+
+- As the second argument, like this:
+
+```javascript
+aws4.sign(requestOptions, {
+  secretAccessKey: "<your-secret-access-key>",
+  accessKeyId: "<your-access-key-id>",
+  sessionToken: "<your-session-token>"
+})
+```
+
+- From `process.env`, such as this:
+
+```
+export AWS_SECRET_ACCESS_KEY="<your-secret-access-key>"
+export AWS_ACCESS_KEY_ID="<your-access-key-id>"
+export AWS_SESSION_TOKEN="<your-session-token>"
+```
+
+(will also use `AWS_ACCESS_KEY` and `AWS_SECRET_KEY` if available)
+
+The `sessionToken` property and `AWS_SESSION_TOKEN` environment variable are optional for signing
+with [IAM STS temporary credentials](http://docs.aws.amazon.com/STS/latest/UsingSTS/using-temp-creds.html).
+
+Installation
+------------
+
+With [npm](http://npmjs.org/) do:
+
+```
+npm install aws4
+```
+
+Can also be used [in the browser](./browser).

+
+Thanks to [@jed](https://github.com/jed) for his

+committed and subsequently extracted this code.
+
+Also thanks to the
+[official node.js AWS SDK](https://github.com/aws/aws-sdk-js) for giving
+me a start on implementing the v4 signature.
