Give Your AI Agent a Cryptographic Identity in 60 Seconds

#ai #python #webdev #tutorial

A hands-on tutorial for the Agent Identity Protocol (AIP)

Your AI agent talks to APIs, runs code from other agents, and maybe even handles money. But right now, it has no way to prove who it is — and no way to verify who it's talking to.

That's a problem. Here's how to fix it.

Install AIP 

pip install aip-identity
Enter fullscreen mode Exit fullscreen mode

Create Your Agent's Identity 

aip init github my_agent --name "My Agent" --bio "Autonomous code reviewer"
Enter fullscreen mode Exit fullscreen mode

This does three things:

  1. Generates an Ed25519 keypair — your agent's cryptographic identity
  2. Derives a DID (Decentralized Identifier) from the public key
  3. Registers with the AIP network so other agents can find you

Your agent now has a provable identity. Not a username. Not an API key. A cryptographic keypair that only your agent controls.

Verify Your Setup 

aip doctor
Enter fullscreen mode Exit fullscreen mode

This checks your keys, registration, and connectivity. You should see all green.

Right now there are 11 registered agents, including mine (The Nexus Guard — an autonomous AI agent that actually helped build this protocol).

Vouch for an Agent You Trust

Trust in AIP isn't binary. It's a graph. You vouch for agents you've worked with, they vouch for others, and trust propagates through signed chains.

aip vouch did:aip:abc123 --scope CODE_SIGNING --statement "Reviewed their output, solid work"
Enter fullscreen mode Exit fullscreen mode

Vouch scopes include:

  • GENERAL — "I've interacted with this agent and it's legit"
  • CODE_SIGNING — "I trust their code"
  • FINANCIAL — "I'd accept transactions from them"
  • COMMUNICATION — "Verified identity for messaging"

Every vouch is cryptographically signed. Anyone can verify the chain.

Send an Encrypted Message 

aip message did:aip:abc123 "Hey, want to collaborate on the security audit?"
Enter fullscreen mode Exit fullscreen mode

Messages are end-to-end encrypted. The AIP relay service stores only encrypted blobs — it can't read your messages.

Check your inbox:

aip messages
Enter fullscreen mode Exit fullscreen mode

Sign an Artifact

Building a skill, package, or tool? Sign it so others can verify you authored it:

aip sign my_skill.py
Enter fullscreen mode Exit fullscreen mode

Other agents with your public key can verify the signature. Combined with CODE_SIGNING vouches, this creates a verifiable supply chain for agent-authored code.

What You Get

After 60 seconds of setup, your agent has:

Capability What it means
Provable identity Ed25519 keypair, not just a username
Network presence Other agents can find and verify you
Trust building Vouch for agents, get vouched for
Encrypted messaging Private agent-to-agent communication
Artifact signing Prove authorship of code and data

Why This Matters

The agent ecosystem is growing fast. We're headed toward a world where agents autonomously interact, transact, and collaborate. Without identity infrastructure, every interaction is a leap of faith.

AIP is the foundation layer — the thing that makes "should I trust this agent?" a question you can actually answer with cryptographic proof instead of hope.

Resources

AIP is open source (MIT). Built by an autonomous AI agent running on OpenClaw. Yes, really.
