Bcrypt + Sequelize password not saving as hash in DB - express

Question

Sequelize + Bcrypt not storing passwords in DB as hash
As the title says, whenever I attempt to store a user into my SQLite DB the console outputs the password as a hash but when I look into the DB with DBbrowser I can see the plaintext password.
Model
// const Promise = require('bluebird')
const bcrypt = require('bcrypt')
async function hashPassword (user, options) {
if (!user.changed('password')) {
return 0
}
const SALT_FACTOR = 8
await bcrypt.hash(user.password, SALT_FACTOR, (err, hash) => {
if (err) {
console.log(err)
}
// user.setDataValue('password', hash)
user.password = hash
console.log(user)
})
}
module.exports = (sequelize, DataTypes) => {
const User = sequelize.define('User', {
email: {
type: DataTypes.STRING,
unique: true
},
password: DataTypes.STRING
}, {
hooks: {
beforeSave: hashPassword,
beforeCreate: hashPassword
}
})
User.prototype.comparePassword = function (password) {
bcrypt.compare(password, this.password, function (res, err) {
if (res) {
console.log(res)
} else {
console.log(err)
}
})
return bcrypt.compare(password, this.password)
}
return User
}
Controllers
module.exports = {
async register (req, res) {
try {
const user = await User.create(req.body)
const userJson = user.toJSON()
res.send({
user: userJson,
token: jwtSignUser(userJson)
})
} catch (err) {
// e-mail already exists or such
res.status(400).send({
error: 'This email address is already in use'
})
}
},
async login (req, res) {
try {
// Grab user input
const { email, password } = req.body
const user = await User.findOne({
where: {
email: email
}
})
// Check to see if user is in db
if (!user) {
res.status(403).send({
error: 'the login information was incorrect / Not Found'
})
}
// Check to see if password is valid
const isPasswordValid = await user.comparePassword(password)
if (!isPasswordValid) {
return res.status(403).send({
error: 'The login information was incorrect'
})
}
// return user using toJSON()
const userJson = user.toJSON()
res.send({
user: userJson,
token: jwtSignUser(userJson)
})
} catch (e) {
res.status(500).send({ error: 'An error occured attempting to login' })
console.log(e)
}
}
}
To elaborate a little more, whenever I create a user, I receive the following:
{
"user": {
"id": 1,
"email": 'test#test.com",
"password": "$2b$08$SYYXU/GDSCFsp3MVeuqrduI0lOLHeeub7whXiaMMoVxO53YJry.1i",
"updatedAt": "2018-09-07T22:44:12.944Z",
"createdAt": "2018-09-07T22:44:12.944Z"
},
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwiZW1haWwiOiJTVVBCUkhVQGxvbC5jb20iLCJwYXNzd29yZCI6IiQyYiQwOCRTWVlYVS9HRFNDRnNwM01WZXVxcmR1STBsT0xIZWV1Yjd3aFhpYU1Nb1Z4TzUzWUpyeS4xaSIsInVwZGF0ZWRBdCI6IjIwMTgtMDktMDdUMjI6NDQ6MTIuOTQ0WiIsImNyZWF0ZWRBdCI6IjIwMTgtMDktMDdUMjI6NDQ6MTIuOTQ0WiIsImlhdCI6MTUzNjM2MDI1MywiZXhwIjoxNTM2OTY1MDUzfQ.mDaeIikzUcV_AGTuklnLucx9mVyeScGpMym1y0kJnsg"
}
Which to me says the DB successfully hashed my password, and stored it. The overhanging issue for me with this is the fact that I believe it's causing the bcrypt.compare function to spit out 'false'. As always, any insight or help would be greatly appreciated!

Answer 1

I'm pretty sure that this answer is too late for you, but might help others landing on this same question.
The main issue I can see is how you are using the async/await pattern. Changing this:
async function hashPassword (user, options) {
if (!user.changed('password')) {
return 0
}
const SALT_FACTOR = 8
await bcrypt.hash(user.password, SALT_FACTOR, (err, hash) => {
if (err) {
console.log(err)
}
// user.setDataValue('password', hash)
user.password = hash
console.log(user)
})
}
to this, worked for me:
async function hashPassword(user, options) {
if (!user.changed("password")) {
return 0;
}
user.password = await bcrypt.hash(user.password, SALT_FACTOR);
}

Answer 2

Can you please try to add only one hook
hooks: {
beforeSave: hashPassword,
}
Because I think your password is getting hashed two times. as beforeSave and beforeCreate both hooks get executed.
Hope it helps
