About

OpenToken implementation

https://tools.ietf.org/html/draft-smith-opentoken-02

Installation

npm install --save @cibel/opentoken

Usage

Example

Import

const OpenToken = require('@cibel/opentoken');

Encoding

Instantiation

// instantiate with pbe password
const otk = new OpenToken('mypassword');

//or instantiate with options
const otk = new OpenToken('mypassword',{notAfter: 300,renewUntil: 300, cipher: OpenToken.CIPHER_AES_256_CBC});

Encoding from raw data

//Encode from raw OpenToken format
const subject = 'Alice';
const payload = 'foo=bar\nbar=baz';
const token = otk.encode(payload, subject);
console.log(token); 
//T1RLAQHYWXG5ELaGj5iUPQr-Enh5Jnm1jxB1xYzddUN5Et3jhYtn4coNAABwodDZZuXqG-lAHs9QGYeyjILE-KmR3lqnD-0wTpEUmQH98WaW0x0fscslpO8A8uqyfWaCuTkeSQOvkit7on1Sb-qg_dnGKLmt0sWigzPhRnNfv5RnpN8lByqwZgL8VIDq3IbSrHGVyvtZ55KC6n1ttQ**

Encoding from Map

// Encode from map
const subject = 'Alice';
const payload =  new Map(['foo','bar'],['bar','baz']);
const token = otk.encodeMap(payload, subject);
console.log(token);
//T1RLAQHYWXG5ELaGj5iUPQr-Enh5Jnm1jxB1xYzddUN5Et3jhYtn4coNAABwodDZZuXqG-lAHs9QGYeyjILE-KmR3lqnD-0wTpEUmQH98WaW0x0fscslpO8A8uqyfWaCuTkeSQOvkit7on1Sb-qg_dnGKLmt0sWigzPhRnNfv5RnpN8lByqwZgL8VIDq3IbSrHGVyvtZ55KC6n1ttQ**

Decoding

Instantiation

const otk = new OpenToken('mypassword');

Decode to OpenToken format

const data = otk.decode(token);
console.log(data);

Decode to Map

const data = otk.decodeAsMap(token);
console.log(data);
//Map { 'subject' => 'Alice','not-before' => '2019-12-06T14:12:53Z','not-on-or-after' => '2019-12-06T14:17:53Z','renew-until' => '2019-12-06T14:17:53Z','foo' => 'bar','bar' => 'baz'
  }

Validation

const otk = new OpenToken('mypassword');
const data = otk.validate(token);

//If we want to validate the subject as well
const subject = 'Alice';
const data = otk.validate(token,subject);
console.log(data);
