Behaviour for signing and verifying tokens.

If you are using Phauxth for token authentication, email confirmation or password resetting, you will need to define a module in your app that uses this behaviour (see the examples section below).

After you have created the token module, add the token_module value to the phauxth config:

config phauxth, token_module: MyAppWeb.Auth.Token

Use the token module to sign the tokens, and then Phauxth will use this module to verify the tokens.

Examples

The following is an example token module using Phoenix tokens.

defmodule MyAppWeb.Auth.Token do
  @behaviour Phauxth.Token

  alias Phoenix.Token
  alias MyAppWeb.Endpoint

  @token_salt "JaKgaBf2"

  @impl true
  def sign(data, opts \ []) do
    Token.sign(Endpoint, @token_salt, data, opts)
  end

  @impl true
  def verify(token, opts \ []) do
    Token.verify(Endpoint, @token_salt, token, opts)
  end
end
