# PKCS #15 Smartcard Sign

This module allows you to sign anything with a private key stored on PKCS #15 smartcard.  

For example, you can upload your key to YubiKey and generate signatures.

## How it works

It's using [`pkcs15-crypt`](https://linux.die.net/man/1/pkcs15-crypt) to process signatures. If it's not installed, you will get an error. 

## Example

```javascript

const signer = require('pkcs15-smartcard-sign');

// Basic usage:

//  - SHA-256

//  - Read key with ID 02

//  - Prompt for PIN

signer.sign({

    data: Buffer.from('something')

}).then(signature => {

    console.log(signature.toString('hex'));

}).catch(err => {

    console.error(err);

});

// Advanced options

signer.sign({

    data,

    // predefined PIN

    pin: '0000',

    // ID of the key to use (on the smart card)

    key: '03',

    // algo: sha256 or sha512

    algo: 'sha512',

    // select N-th smart card reader configured by the system

    reader: 2,

    // verify with this public key after sign

    verifyKey: fs.readFileSync('your-public-key.pem')

});

```
