Json Web Tokens Example

jwt.js

var fs = require('fs');
var jwt = require('jsonwebtoken');

var token = jwt.sign({ foo: 'bar' }, 'blah');

var decoded = jwt.verify(token, 'blah');
console.log("Decodable at https://jwt.io/#debugger", token, decoded.foo); // bar

// invalid token - synchronous
try {
  var decoded = jwt.verify(token, 'wrong-secret');
} catch(err) {
  // err
  console.log(err);
}



var cert = fs.readFileSync('private.pem');  // get private key
var token = jwt.sign({ foo: 'bar' }, cert, { algorithm: 'RS256'});

// sign asynchronously
jwt.sign({ foo: 'bar' }, cert, { algorithm: 'RS256' }, function(err, token) {
  console.log(token);
});

var cert = fs.readFileSync('public.pem');  // get public key
jwt.verify(token, cert, function(err, decoded) {
  console.log(decoded.foo) // bar
});
