a password class i'm using in my nodejs project. i decided this abstraction was appropriate given a desire to create password hashs asyncly.

password.coffee

bcrypt = require 'bcrypt'

class password

	text = null
	salt = null
	hash = null

	@saltAndHash = (text, done) ->
		bcrypt.genSalt (err, salt) ->
			if err
				return done err
			password.hash text, salt, (err, pwd) ->
				return done err, pwd

	@hash = (text, salt, done) ->
		pwd = new password
		pwd.text = text
		pwd.salt = salt
		bcrypt.hash text, salt, (err, hash) ->
			if err
				return done err
			pwd.hash = hash
			return done null, pwd

module.exports = password
