jwt-js v0.5.0

JSON Web Token JS

node.js library for signing, decoding, and verifying JSON Web Tokens (JWTs)

Installation

npm install jwt-js

Signing Tokens

var TokenSigner = require('jwt-js').TokenSigner,
    rawPrivateKey = '278a5de700e29faae8e40e366ec5012b5ec63d36ec77e8a2417154cc1d25383f',
    tokenPayload = {"issuedAt": "1440713414.85", "challenge": "7cd9ed5e-bb0e-49ea-a323-f28bde3a0549", "issuer": {"publicKey": "03fdd57adec3d438ea237fe46b33ee1e016eda6b585c3e27ea66686c2ea5358479", "chainPath": "bd62885ec3f0e3838043115f4ce25eedd22cc86711803fb0c19601eeef185e39", "publicKeychain": "xpub661MyMwAqRbcFQVrQr4Q4kPjaP4JjWaf39fBVKjPdK6oGBayE46GAmKzo5UDPQdLSM9DufZiP8eauy56XNuHicBySvZp7J5wsyQVpi2axzZ", "blockchainid": "ryan"}},
    token = new TokenSigner('ES256k', rawPrivateKey).sign(tokenPayload)

Example output:

Decoding Tokens

var decodeToken = require('jwt-js').decodeToken,
    tokenData = decodeToken(token)

Example output:

> console.log(tokenData)
{ header: { alg: 'ES256', typ: 'JWT' },
  payload: 
   { issuedAt: '1440713414.85',
     challenge: '7cd9ed5e-bb0e-49ea-a323-f28bde3a0549',
     issuer:

Verifying Tokens

var TokenVerifier = require('jwt-js').TokenVerifier,
    rawPublicKey = '03fdd57adec3d438ea237fe46b33ee1e016eda6b585c3e27ea66686c2ea5358479',
    verified = new TokenVerifier('ES256k', rawPublicKey).verify(token)

Example output:

> console.log(verified)
