from aps import AgentPassport, PassportConfig, Skill, Soul, Policies, Lineage, generate_key_pair
from cryptography.hazmat.primitives.serialization import Encoding, PublicFormat

public_key, private_key = generate_key_pair()
public_key_hex = public_key.public_bytes(Encoding.Raw, PublicFormat.Raw).hex()

passport = AgentPassport.new(PassportConfig(
    id="did:key:z6MkExample",
    public_key=public_key_hex,
    owner_did="did:key:z6MkOwner",
    skills=[Skill("python", "1.0.0", "Python agent", ["code_write"], "0x" + "ab" * 32)],
    soul=Soul("focused", "test-first", [], "0x" + "cd" * 32),
    policies=Policies("0x" + "ef" * 32, ["read-only"]),
    lineage=Lineage("original", [], 0),
))
