I am using JWT-simple for authenticating my express routes.
server side:
var jwt = require('jwt-simple');
var bcrypt = require('bcrypt');
var passport = require('passport');
require('../passport')(passport);
/* Create an Account */
router.post('/signup', function (req, res, next) {
var verifyCode = Math.random().toString(36).slice(-8);
var userData = {
name: req.body.name,
email: req.body.email,
phone: req.body.contact,
password: req.body.password,
verify_code: verifyCode,
status: 0
};
loginService.createUser(userData, function (err, data) {
if (err) {
res.status(500).json({error: true, data: {message: err.message}});
} else {
var token = jwt.encode(data, "secret");
res.json({success: true, data: {token: 'JWT ' + token}});
}
});
});
/* GET the info of an API using the jwt token data */
router.get('/info', passport.authenticate('jwt', {session: false}), function (req, res, next) {
var token = tokenRetrive.getToken(req.headers);
if (token) {
var decoded = jwt.decode(token, configVar.config.secret);
UserService.getContentUserById(decoded.id, function (err, user) {
if (err) {
res.status(500).json({error: true, data: {message: err.message}});
} else {
if (!user) {
res.send({success: false, msg: 'Authentication failed. User not found.'});
} else {
if (!user) {
return res.status(403).send({success: false, msg: 'Authentication failed. User not found.'});
} else {
res.json({success: true, data: user.toJSON()});
}
}
}
});
} else {
return res.status(403).send({success: false, msg: 'No token provided.'});
}
});
client side
var signup = function(user) {
return $q(function(resolve, reject) {
$http.post(API_ENDPOINT.url + '/signup', user).then(function(result) {
if (result.data.success) {
storeUserCredentials(result.data.data.token);
resolve(result.data);
} else {
reject(result.data.msg);
}
});
});
};
function storeUserCredentials(token) {
window.localStorage.setItem(TOKEN_KEY, token);
var loggedIn_user_Data = jwt_decode(token);
$http.defaults.headers.common.Authorization = token;
}
Using REST client (POSTMAN) when I pass the header info to the API I use
API : localhost:8080/info
Key
Authorization
Content-Type
Value
JWT eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJuYW1lIjoiYXR1bCIsImVtYWlsIjoidHJlZUB0cmVlLmNvbSIsInBob25lIjpudWxsLCJwYXNzZHJlc3MiOm51bGwsImNvdW50cnkiOm51bGwsInN0YXRlIjpudWxsLCJwaW5jb2RlIjpudWxsLCJvcmdfaWQiOjAsInJvbGVzIjpudWxsLCJjcmVhdGVfZGF0ZSI6IjIwMTctMDUtMThUMTk6NTE6MDYuMDAwWiIsImxhc3RfbG9naW4iOiIyMDE3LTA1LTE4VDE5OjUxOjA2LjAwMFoiLCJhdmF0YXJfdXJsIjpudWxsfQ.umxBRd2sazaADSDOW0e8rO5mKDpQYIK1hsaQMZriZFE
application/json
The above API gives me the data only if the correct token is passed and seems working fine.
However in client side I can get the token retrieve using jwt-decode, without the use of any secret in client side, what if the token is caught by middle man, How can the security be enhanced?
Is there something I am missing to have correct use of JWT for my node api routes?
Some places I see the Authorisation is passed as bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJuYW1lIjoiYXR1bCIsImVtYWlsIjoidHJlZUB0cmVlLmNvbSIsInBob25lIjpudWxsLCJwYXNzd29yZCI6IiQyYSQxMCRIQVJPTy5PUEdYWFBvVktXOVhmYnZldk
When I try to use bearer I get error to get the info after authenticating.
What is this bearer and JWT being passed in value to header?
I am using passport-jwt var JwtStrategy = require('passport-jwt').Strategy;
