What is Pilot Certificate?
Pilot Certificate is a specialized tool within the Openclaw Skills ecosystem designed for secure, decentralized authorization. Unlike traditional PKI which focuses on identity, this skill implements a capability-based security model. It allows agents to issue time-limited, signed proofs that grant specific permissions (like read, write, or admin) to other subjects in the network.
By leveraging Ed25519 signatures and standard JSON structures, it provides a lightweight yet robust way to manage delegated authority. This ensures that agents can interact with high confidence, verifying the rights of their peers through cryptographic validation rather than just simple trust relationships.
Pilot Certificate Use Cases
- Issuing granular capability proofs for autonomous agent interactions.
- Authorizing delegated tasks with strict, time-limited expiration windows.
- Verifying agent permissions across a distributed network using cryptographic signatures.
- Managing temporary access control for shared resources without long-term credential exposure.
How Pilot Certificate Works
- Generation: The skill generates a unique certificate ID and defines the subject and capability set (e.g., read, write).
- Issuance: A JSON-formatted certificate is created, including a UTC expiration timestamp.
- Distribution: The certificate is transmitted to the recipient agent via the pilotctl protocol.
- Validation: The receiving agent or resource owner verifies the certificate by checking the cryptographic signature and ensuring the current system time is before the expiration timestamp.
- Enforcement: Permission is granted only if the specific required capability is explicitly listed within the active certificate.
Pilot Certificate Setup
To utilize this skill within the Openclaw Skills framework, ensure you have the necessary dependencies installed and the Pilot daemon active.
# Ensure pilotctl is in your PATH
pilotctl daemon start
# Create the directory structure for certificate management
mkdir -p ~/.pilot/certificates/{issued,received}
# Verify dependencies
which jq openssl pilotctl
Pilot Certificate Data Schema & Taxonomy
The skill organizes data within the ~/.pilot/certificates/ directory using the following structure:
| Field | Type | Description |
|---|---|---|
certificate_id |
String | Hexadecimal unique identifier for the certificate. |
subject |
Object | Contains agent metadata, typically the hostname. |
capabilities |
Array | List of granted permissions (e.g., ["read", "admin"]). |
expires_at |
String | ISO 8601 formatted UTC timestamp. |
status |
String | The current state of the cert (e.g., "active"). |
Pilot Certificate Advanced Features
- Automated Expiry Verification: Integrated logic to instantly invalidate certificates based on system epoch time.
- Granular Capability Mapping: Support for complex permission arrays tailored for multi-agent workflows.
- JSON-based Interoperability: Uses standard jq-compatible formats for easy integration with other Openclaw Skills.
- Secure Delegation: Facilitates safe hand-offs between agents using short-lived authorization tokens.
