DIAP Python SDK

Decentralized Intelligent Agent Protocol (DIAP) SDK for Python.

A Python implementation of the DIAP protocol for decentralized identity management and agent authentication using zero-knowledge proofs.

Features

• Decentralized Identity: W3C DID:key implementation
• Zero-Knowledge Proofs: Real BN128 elliptic-curve Schnorr proofs via py_ecc (snarkjs CLI as optional backend)
• IPFS Integration: Decentralized storage with IPNS support
• P2P Networking: Real iroh gossip communication + libp2p identity/signing
• Agent Authentication: Secure agent identity and verification
• Encryption: Ed25519 keys (pynacl, RFC 8032) with AES-256-GCM + ECIES encryption

Installation

pip install diap-sdk

Or install from source:

git clone https://github.com/logos-42/DIAP_Python_SDK.git
cd DIAP_Python_SDK
pip install -e .

Quick Start

from diap import KeyManager, DIDBuilder

# Generate a key pair
km = KeyManager()
key_pair = km.generate()

# Create DID document
builder = DIDBuilder()
doc = builder.create_did_document(key_pair)
print(f"DID: {doc.id}")

Development

Install development dependencies:

pip install -e ".[dev]"

Run tests:

pytest tests/
