u2f_ex v0.5.0 U2FEx.PKIStorageBehaviour behaviour

This is a way for you to store the key metadata required by u2f_ex in any manner you choose.

An example can be seen here:

defmodule App.PKIStorage do
  @behaviour U2FEx.PKIStorageBehaviour
  @moduledoc false
  import Ecto.Query

  alias App.U2FKeys

  @impl PKIStorageBehaviour
  def list_key_handles_for_user(user_id) do
    q =
    from(u in U2FKeys,
    where: u.id == ^user_id
    )

    q
    |> Repo.all()
    |> Enum.map(fn %U2FKeys{version: version, key_handle: key_handle, app_id: app_id} ->
      %{version: version, key_handle: key_handle, app_id: app_id}
    end)
  end
end
