SPIFFE / SPIRE

Stub

SPIFFE (Secure Production Identity Framework for Everyone) is the open standard for cryptographic workload identity. SPIRE is the reference implementation. Together they’re the substrate the AI Agent Identity Architecture page recommends for assigning verifiable identities to AI agents (24 mentions of SPIFFE and 14 of SPIRE across the vault).

Pending content: identity-document format (SVID), trust domains, attestation flow, how it slots into delegated vs. autonomous-agent identity models, comparison to OAuth/OIDC.
