```bash
git clone https://git.coolaj86.com/coolaj86/bluecrypt-jwk-to-ssh.js
pushd bluecrypt-jwk-to-ssh.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-jwk-to-ssh.js/raw/branch/master/jwk-to-ssh.js"></script>
```

It's also on npm:

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

# Usage

Very simple:

```js
var jwk = {
  "kty": "EC",
  "crv": "P-256",
  "x": "IT1SWLxsacPiE5Z16jkopAn8_-85rMjgyCokrnjDft4",
  "y": "mP2JwOAOdMmXuwpxbKng3KZz27mz-nKWIlXJ3rzSGMo"
};

var pub = SSH.pack({ jwk: jwk, comment: 'root@localhost' });

console.info(pub);
```
