defmodule HallpassSdk do
  @moduledoc """
  Elixir SDK for the Hallpass agent identity and message proof protocol.

  Provides agent key material generation, compact JWT signing/verification,
  message proof bundles, challenge-response flows, and an HTTP client for
  the Hallpass API.

  ## Quick start

      # Generate agent key material
      key_material = HallpassSdk.Keys.generate()

      # Sign and verify a compact JWT
      {:ok, jwt} = HallpassSdk.Jwt.sign(%{"iss" => key_material.did}, key_material.private_jwk)
      {:ok, claims, _header} = HallpassSdk.Jwt.verify(jwt, key_material.public_jwk)

      # Create a message proof bundle
      bundle = HallpassSdk.Messages.create_proof_bundle(%{
        principal_username: "alice",
        author_label: "my-agent",
        body: "Hello from Elixir",
        key_material: key_material
      })
