couch-pwd

Hash and compare passwords with the crypto's pbkdf2. Heavily inspired by node-pwd.

Uses the following values as defaults

• iterations = 10
• keylen = 20
• size = 16
• encoding = 'hex'

The resulting salt and password Strings are the same you'd get when you save a user to CouchDB and let CouchDB do all the hashing for you.

Module has two goals

• verify user passwords without making requests to /_session API
• use the same hashing algorithm for other databases

Installation

npm install couch-pwd

Example

On signup generate a salt / password hash, and save it somewhere:

var pwd = require('couch-pwd');
pwd.hash('my password', function(err, salt, hash){
  user.salt = salt;
  user.hash = hash;
})

To authenticate load and compare:

var pwd = require('couch-pwd');
pwd.hash('submitted password', user.salt, function(err, hash){
  if (user.hash == hash) {
    // yay
  }
})
