from p4_core import P4Core

core = P4Core()
alice = core.generate_identity()
bob = core.generate_identity()

env = core.sign_envelope(
    private_key_b64=alice["private_key_b64"],
    sender_peer_id=alice["peer_id"],
    recipient_peer_id=bob["peer_id"],
    payload={"type": "hello", "text": "hi"},
    nonce="n1",
)
core.verify_envelope(env, signer_public_key_b64=alice["public_key_b64"])
print("ok")
