Hashifier

Light-weight wrapper to nodejs crypto library for hashing passwords using pbkdf2

Requirements

node 6.

Install

npm install hashifier

API

Each function returns a promise that resolves as specified.

Any errors encountered by nodejs (i.e. passing 0 for iterations) will reject the promise.

hash(plainText, options?)

• hash a given password
• resolves to an object, {hash, salt}
• see options below

compare(plainText, hash, salt, options?)

• compare a previously hashed password
• resolves to a boolean
• see options below

options

• iterations - number of iterations to hash (default 100,000)
• algorithm - algorithm to use for hashing (default sha512)
• encoding - output encoding to use (default hex)
• saltLength - number of bytes to use for the salt (default 128)
• keyLength - length of the key (default 128)

Usage

const hashifier = require('hashifier')

// options are optional, following is default
const options = {
  iterations: 100000
  algorithm: 'sha512'
  encoding: 'hex'
  saltLength: = 128
  keyLength: 128
}

hashifier.hash('my password', options) // {salt: string, hash: string}
  .then(result => {
    hashifier.compare('my password', result.hash, result.salt, options).then(result => assert.ok(result)) // true
    hashifier.compare('not my password', result.hash, result.salt, options).then(result => result.notOk(result)) // false
  })
