<br>

Environments Supported

- Nodejs
- Web Workers
  - ex. Cloudflare Workers

## Installation

```sh
npm install jwks-slim
```

## Initialization

```js
const { JwksClient } = require("jwks-client");
const client = new JwksClient({
  jwksUri: "your-jwks-endpoint",
  cache: true,  //default: true
  requestHeaders: {}  //optional
});
```

## Usage

```js
const kid = "RkI5MjI5OUY5ODc1N0Q4QzM0OUYzNkVGMTJDOUEzQkFCOTU3NjE2Rg";
const key = await client.getSigningKey(kid);
const signingKey = key.publicKey;
console.log(signingKey);

// Output 
/**

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
