## Getting Started
### Installation
Using [npm](https://npmjs.org) in your project directory run the following command:
````bash
npm install --save jwks-rsa
````
Supports all currently registered JWK types and JWS Algorithms, see [panva/jose#262](https://github.com/panva/jose/issues/262) for more information.
### Configure the client
Provide a JWKS endpoint which exposes your signing keys.
````js
const jwksClient = require('jwks-rsa');
const client = jwksClient({
jwksUri: 'https://sandrino.auth0.com/.well-known/jwks.json',
requestHeaders: {}, // Optional
timeout: 30000 // Defaults to 30s
});
````
### Retrieve a key
Then use `getSigningKey` to retrieve a signing key that matches a specific `kid`.
````js
const kid = 'RkI5MjI5OUY5ODc1N0Q4QzM0OUYzNkVGMTJDOUEzQkFCOTU3NjE2Rg';
const key = await client.getSigningKey(kid);
const signingKey = key.getPublicKey();
````
