Agentic Profile Authentication Library

An Agentic Profile is a JSON-LD/DID Document at a well known network location that becomes a DID URI for a person, business, or other entity. DID URIs can resolve to an HTTPS endpoint, on a blockchain, and many other services that are defined by the DID specification. For example, the URI did:web:iamagentic.ai/mike is a universal identifier that can be used to discover AI agents that represent Mike.

For a demonstration of this library and examples of its implemention, please download the SDK

The Agentic Profile provides a means for authentication using strong public key cryptography. Each Agentic Profile publishes the current public key(s) for a person, and may also publish the public keys for the person's agents.

When the person (or an agent (A) of that person) attempts to communicate with another agent/service (B), the other agent (B) may provide a challenge and ask for the challenge to be signed by A. If the challenge signature is verified by B, then B can be assured it is communicating with A.

The Agentic Profile supports a protocol that is:

Open source and based on W3C and IETF standards
Light weight and easy to implement
Very secure using strong public key cryptography (ed25519 by default) and the JSON Web Signature (JWS) standards
Decentralized, anyone can publish an Agentic Profile DID resolvable service
Fine grained/multi-tenant, allowing a single web service to handle many users/agents/tenants
Extensible, supporting any number of agents for a single profile, and allowing the agents to communicate in any protocol they agree on
