Overview
========

[](#overview)

The HMAC authentication component for Tokenly.

[![Build Status](https://camo.githubusercontent.com/1ad99e6aaa4947a9bc44544f20dfe4721ccc612f9fc9f6a895e93f14b7f37188/68747470733a2f2f7472617669732d63692e6f72672f746f6b656e6c792f686d61632d617574682e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/tokenly/hmac-auth)

Authentication
==============

[](#authentication)

To authenticate HTTP requests that use this component, you must include 3 HTTP headers with your request:

1. X-Tokenly-Auth-Api-Token
2. X-Tokenly-Auth-Nonce
3. X-Tokenly-Auth-Signature

To generate these headers, you will need an API Token and a secret API Key.

Say my API Token is `TWKTkwIQDTvirh6D` and my API Secret key is `Kun2M2UladalYAeUvXyiKWhFuwrsmSreM841K45O`. Here is an explanation of each header.

### X-Tokenly-Auth-Api-Token

[](#x-tokenly-auth-api-token)

This token is nothing more than the API Token.

Example: `X-Tokenly-Auth-Api-Token: TWKTkwIQDTvirh6D`

### X-Tokenly-Auth-Nonce

[](#x-tokenly-auth-nonce)

The nonce header is the current unix timestamp in seconds.

Example: `X-Tokenly-Auth-Nonce: 1457530047`

### X-Tokenly-Auth-Signature

[](#x-tokenly-auth-signature)

The signature is a base64 encoded string using sha256 HMAC. The key for the hash is the API Key. And the message is generated using the following data:

```
{METHOD}\n
{URL}\n
{PARAMETERS}\n
{API TOKEN}\n
{NONCE}

```

{METHOD} is the http method such as GET,POST,PUT,DELETE {URL} is the full URL of the api endpoint {PARAMETERS} are required and should be a JSON encoded string representing the parameters. For empty parameters, use `{}`. {API TOKEN} and {NONCE} are the same as send in the headers.

Items are separated with a single newline character.

After calculating the HMAC, encode the data in base64 format.

Example:

Using the values above and a request of GET , the signature header will be:

`X-Tokenly-Auth-Signature: hZ6SDgcZzo5AYrS9yopEQo068ax0NojG/CfXWG+RJEA`
