Registri identity — Ed25519 keypairs, certificates, and cryptographic verification

agent-registry-identity

Agent identity infrastructure for the Agent Registry — Ed25519 keypairs, certificates, and cryptographic verification.

Overview

Provides the cryptographic identity layer for AI agents, similar to what Let's Encrypt does for websites. Agents can generate keypairs, sign messages, and verify each other's identity.

Installation

pip install agent-registry-identity

Features

• Ed25519 keypair generation — create signing keys for agents
• Message signing and verification — cryptographically sign outbound messages
• Certificate issuance — agent identity certificates
• Challenge-response verification — prove ownership of an agent's private key
• GitHub and DNS verification — alternative verification paths

Quick Start

from agent_registry_identity import generate_keypair, sign_message, verify_signature

# Generate a new keypair
private_key, public_key = generate_keypair()

# Sign a message
signature = sign_message(private_key, b"hello from my agent")

# Verify the signature
is_valid = verify_signature(public_key, b"hello from my agent", signature)
