#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

How To Load The HIBP Pwned Passwords Database Into Redis

NIST recommends that when users are trying to set a password you should reject those that are commonly used or compromised:

When processing requests to establish and change memorized secrets, 
verifiers SHALL compare the prospective secrets against a list that 
contains values known to be commonly-used, expected, or compromised.

But how do you know what are the compromised passwords? Luckily Troy Hunter put a lot of effort into building the "Have I Been Pwned (HIBP)" database with the SHA1 hashes of 501,636,842 passwords that have been compromised on the internet. Sweet.
