pw-hasher

This module provides straight-forward password hashing for node.js applications using default settings considered to be safe.

Usage

First, install the module:

$ npm install pw-hasher --save

Afterwards, usage is as simple as shown in the following example:

const pwHasher = require('../index')

const myuser = []

try {
  myuser.hash = pwHasher.hash('mysecret')
} catch (e) {
  console.error(e)
}

let isValid = false;
try {
  isValid = pwHasher.verify('hack', myuser.hash)
} catch (e) {
  console.error(e)
}

if (!isValid) {
  console.log('Nope!')
} else {
  // Velcom to hte thing.
}

Crypto

password-hash-and-salt uses node.js' internal crypto module. Hashes are generated with pbkdf2 using 10,000 iterations.

Created hash

The created hash is of 270 characters length and is of the following format: pbkdf2$10000$hash$salt

This allows for future upgrades of the algorithm and/or increased number of iterations in future version. It also simplifies storage as no dedicated database field for the salt is required.
