Provides functions for hashing passwords and authenticating users using Comonin.Bcrypt.

This module assumes that you have a virtual field named password, and a database backed string field named hashed_password.

Usage

Example

defmodule User do
  import Doorman.Auth.Bcrypt, only: [hash_password: 1]

  import Ecto.Changeset

  def create_changeset(struct, changes) do
    struct
      |> cast(changes, ~w(email password))
      |> hash_password
  end
end

To authenticate a user in your application, you can use authenticate/2:

user = Repo.get(User, 1)
User.authenticate(user, "password")
