# api-key-auth
Express/Restify middleware to authenticate HTTP requests based on api key and signature.

## Installation
```
$ npm install --save api-key-auth
```
## Usage
This middleware authenticates callers using an api key and the signature of the request. If the api key and the signature are valid, `req.credentials` will be set with the calling application information.
### Example
This basic usage example should help you get started :
```javascript
const express = require('express');
const apiKeyAuth = require('api-key-auth');
const app = express();
// Create the collection of api keys
const apiKeys = new Map();
apiKeys.set('123456789', {
id: 1,
name: 'app1',
secret: 'secret1'
});
apiKeys.set('987654321', {
id: 2,
name: 'app2',
secret: 'secret2'
});
// Your function to get the secret associated to the key id
function getSecret(keyId, done) {
if (!apiKeys.has(keyId)) {
return done(new Error('Unknown api key'));
}
const clientApp = apiKeys.get(keyId);
done(null, clientApp.secret, {
id: clientApp.id,
name: clientApp.name
});
}
app.use(apiKeyAuth({ getSecret }));
app.get('/protected', (req, res) => {
res.send(`Hello ${req.credentials.name}`);
});
app.listen(8080);
```
## API
### apiKeyAuth(options)
Create an api key based authentication middleware function using the given `options` :
| Name | Type | Default | Description |
| :---------------: | :-------------: | :-------------: | :---------------------------------------------- |
| `getSecret` | `Function` | `-` | Invoked to retrieve the secret from the `keyId` |
| `requestProperty` | `String` | `'credentials'` | The request property to attach the information |
| `requestLifetime` | `Number | null` | `300` | The lifetime of a request in seconds |
#### options.getSecret (REQUIRED)
A function with signature `function(keyId, done)` to be invoked to retrieve the secret from the `keyId`.
- `keyId` (`String`) - The api key used to retrieve the secret.
- `done` (`Function`) - A function with signature `function(err, secret, credentials)` to be invoked when the secret is retrieved.
- `err` (`Error`) - The error that occurred.
- `secret` (`String`) - The secret to use to verify the signature.
- `credentials` (`Object`) - `req.credentials` will be set with this object.
#### options.requestProperty (OPTIONAL)
By default, you can attach information about the client application on `req.credentials` but can be configured with the `requestProperty` option.
#### options.requestLifetime (OPTIONAL)
The lifetime of a request in second, by default is set to 300 seconds, set it to null to disable it. This options is used if HTTP header "date" is used to create the signature.
## HTTP signature scheme
