#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault

##Steps

require 'cgi'
require 'active_support'

def verify_and_decrypt_session_cookie(cookie, secret_key_base = Rails.application.secret_key_base)
  config = Rails.application.config
  cookie = CGI::unescape(cookie)
  salt   = config.action_dispatch.authenticated_encrypted_cookie_salt
  encrypted_cookie_cipher = config.action_dispatch.encrypted_cookie_cipher || 'aes-256-gcm'
  # serializer = ActiveSupport::MessageEncryptor::NullSerializer # use this line if you don't know your serializer
  serializer = ActionDispatch::Cookies::JsonSerializer
