Auth0 plug

A plug for verifing Auth0 JWTs.

Usage

Add to dependencies:

{:auth0_plug, "~> 1.0"}

Configuration:

config :auth0_plug,
  secret: "secret",
  realm: "realm",
  conn_key: :auth0_plug_jwt

You can find the jwt in conn.private:

conn.private[:auth0_plug_jwt]

In case of failure the plug will return automatically a 401. If you don't want that, you can disable it in the options:

config :auth0_plug,
    return_401: false

If you want to customize the error message:

config :auth0_plug,
    unauthorized_message: "Your credentials are invalid"

It's possible to specify which key to extract from the JWT:

config :auth0_plug,
    key_to_extract: "email"
