agentic-identity 0.3.0

Cryptographic trust anchor for AI agents

agentic-identity

Python bindings for the AgenticIdentity cryptographic trust anchor.

Install

pip install agentic-identity

Note: The native shared library must be built first:

cargo build --release -p agentic-identity-ffi

Quick Start

from agentic_identity import Identity, verify_receipt, version

print(f"Library version: {version()}")

# Create a new identity
identity_id = Identity.create(
    path="agent.aid",
    passphrase="strong-passphrase",
    name="my-agent",
)
print(f"Created: {identity_id}")

# Load and use the identity
with Identity.load("agent.aid", "strong-passphrase") as identity:
    print(f"ID: {identity.identity_id}")
    print(f"Public key: {identity.public_key}")

    # Sign an action
    receipt = identity.sign_action(
        action_type="decision",
        description="Approved deployment to production",
    )

    # Verify the receipt
    assert verify_receipt(receipt)
    print("Receipt verified!")

Features

• Zero dependencies — only Python stdlib (ctypes, json, dataclasses)
• Ed25519 signatures — identity anchors, action receipts, trust grants
• Type-safe models — frozen dataclasses for all domain types
• Context manager — automatic cleanup of native handles
• Full FFI coverage — all 11 C API functions bound
