@sl-nx/couch-pwd

An up-to-date version of couch-pwd that is actually published.

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'
• digest = 'SHA1'

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

To authenticate load and compare:

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