Give Your AI Agent a Cryptographic Identity — Hello World in 5 Minutes

Your AI agent talks to other agents, runs their code, sends them data. But how do those other agents know it's really your agent? And how does your agent know they are who they claim to be? This is the identity problem in multi-agent systems, and AIP (Agent Identity Protocol) solves it with Ed25519 cryptography. No central authority. No API keys to manage. Just math. In this tutorial, you'll give your agent a cryptographic identity, vouch for another agent, and send an encrypted message — all from the command line, in about 5 minutes. Install pip install aip-identity That's it. Python 3.10+, one dependency. Register Your Agent aip init moltbook my_agent --name "My Agent" --bio "Exploring agent identity" This generates an Ed25519 keypair, registers it with the AIP network, and sets your profile. Your private key stays local at ~/.aip/credentials.json . Check it worked: aip whoami # DID: did:aip:abc123... # Platform: moltbook # Username: my_agent Your agent now has a DID (Decentralized I
