-[![Build Status](https://api.travis-ci.org/mhart/aws4.png?branch=master)](https://travis-ci.org/github/mhart/aws4)
-
-A small utility to sign vanilla Node.js http(s) request options using Amazon's
-[AWS Signature Version 4](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html).
-
-If you want to sign and send AWS requests in a modern browser, or an environment like [Cloudflare Workers](https://developers.cloudflare.com/workers/), then check out [aws4fetch](https://github.com/mhart/aws4fetch) – otherwise you can also bundle this library for use [in older browsers](./browser).
-
-The only AWS service that *doesn't* support v4 as of 2020-05-22 is
-[SimpleDB](https://docs.aws.amazon.com/AmazonSimpleDB/latest/DeveloperGuide/SDB_API.html)
-(it only supports [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 https = require('https')
-var aws4  = require('aws4')
-
-// to illustrate usage, we'll create a utility function to request and pipe to stdout
-function request(opts) { https.request(opts, function(res) { res.pipe(process.stdout) }).end(opts.body || '') }
-
-// aws4 will sign an options object as you'd pass to http.request, with an AWS service and region
-var opts = { host: 'my-bucket.s3.us-west-1.amazonaws.com', path: '/my-object', service: 's3', region: 'us-west-1' }
-
-// aws4.sign() will sign and modify these options, ready to pass to http.request
-aws4.sign(opts, { accessKeyId: '', secretAccessKey: '' })
-
-// or it can get credentials from process.env.AWS_ACCESS_KEY_ID, etc
-aws4.sign(opts)
-
-// for most AWS services, aws4 can figure out the service and region if you pass a host
-opts = { host: 'my-bucket.s3.us-west-1.amazonaws.com', path: '/my-object' }
-
-// usually it will add/modify request headers, but you can also sign the query:
-opts = { host: 'my-bucket.s3.amazonaws.com', path: '/?X-Amz-Expires=12345', signQuery: true }
-
-// and for services with simple hosts, aws4 can infer the host from service and region:
-opts = { service: 'sqs', region: 'us-east-1', path: '/?Action=ListQueues' }
-
-// and if you're using us-east-1, it's the default:
-opts = { service: 'sqs', path: '/?Action=ListQueues' }
-
-aws4.sign(opts)
-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
-request(opts)
-/*
-<?xml version="1.0"?>
-<ListQueuesResponse xmlns="https://queue.amazonaws.com/doc/2012-11-05/">
-...
-*/
-
-// 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' }))
-/*
-<ListGroupsResponse xmlns="https://iam.amazonaws.com/doc/2010-05-08/">
-...
-*/
-
-// you can specify any custom option or header as per usual
-request(aws4.sign({
-  service: 'dynamodb',
-  region: 'ap-southeast-2',
-  method: 'POST',
-  path: '/',
-  headers: {
-    'Content-Type': 'application/x-amz-json-1.0',
-    'X-Amz-Target': 'DynamoDB_20120810.ListTables'
-  },
-  body: '{}'
-}))
-/*
-{"TableNames":[]}
-...
-*/
-
-// The raw RequestSigner can be used to generate CodeCommit Git passwords
-var signer = new aws4.RequestSigner({
-  service: 'codecommit',
-  host: 'git-codecommit.us-east-1.amazonaws.com',
-  method: 'GIT',
-  path: '/v1/repos/MyAwesomeRepo',
-})
-var password = signer.getDateTime() + 'Z' + signer.signature()
-
-// see example.js for examples with other services
-```
-
-API
----
-
-### aws4.sign(requestOptions, [credentials])
-
-Calculates and populates any necessary AWS headers and/or request
-options on `requestOptions`. Returns `requestOptions` as a convenience for chaining.
-
-`requestOptions` is an object holding the same options that the Node.js
-[http.request](https://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 try to 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 try to be calculated from `hostname` or `host` if not given)
-- `region` (will try to be calculated from `hostname` or `host` or use `'us-east-1'` if not given)
-- `signQuery` (to sign the query instead of adding an `Authorization` header, defaults to false)
-- `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_ACCESS_KEY_ID="<your-access-key-id>"
-export AWS_SECRET_ACCESS_KEY="<your-secret-access-key>"
-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](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_use-resources.html).
-
-Installation
-------------
-
-With [npm](https://www.npmjs.com/) do:
-
-```
-npm install aws4
-```
-
-Can also be used [in the browser](./browser).
-
-Thanks
-------
-
-Thanks to [@jed](https://github.com/jed) for his
-[dynamo-client](https://github.com/jed/dynamo-client) lib where I first
-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.
