# Bluecrypt SSH to JWK (for Browsers)

A minimal library to parse an SSH public key (`id_rsa.pub`)
and convert it into a public JWK using Vanilla JS.

Works for RSA and ECDSA public keys.

### Need SSH Private Keys?

SSH private keys (`id_rsa`) are just normal PEM files,
so you can use Eckles or Rasha, as mentioned above.

```bash
git clone https://git.coolaj86.com/coolaj86/bluecrypt-ssh-to-jwk.js
pushd bluecrypt-ssh-to-jwk.js/
```

```bash
open index.html
```

# Install

You can use it as a plain-old javascript library:

```html
<script src="https://git.coolaj86.com/coolaj86/bluecrypt-ssh-to-jwk.js/raw/branch/master/ssh-to-jwk.js"></script>
```

It's also on npm:

```bash
npm install bluecrypt-ssh-to-jwk
```

# Usage

Very simple:

```js
var pub = 'ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBCE9Uli8bGnD4hOWdeo5KKQJ/P/vOazI4MgqJK54w37emP2JwOAOdMmXuwpxbKng3KZz27mz+nKWIlXJ3rzSGMo= root@localhost';

var ssh = SSH.parse(pub);

console.info(ssh.jwk);
```
