SPIFFE

Secure Production Identity Framework for Everyone (SPIFFE) is a set of open-source standards for securely identifying software systems in dynamic and heterogeneous environments through platform-agnostic, cryptographic identities. SPIFFE defines the SPIFFE ID URI format, the X.509 SVID and JWT SVID identity document formats, and the Workload API for issuing and rotating identities without secrets or passwords. SPIFFE is a graduated CNCF project.

SPIFFE publishes 2 APIs on the APIs.io network: Workload API and Bundle API. Tagged areas include Authentication, Cloud Native, Graduated, Identity, and Security.

The SPIFFE catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 3 Spectral governance rulesets.

SPIFFE’s developer surface includes documentation, getting-started guide, engineering blog, Stack Overflow tag, and 13 more developer resources.

  description: The SPIFFE Workload API is a gRPC streaming interface through which workloads request and receive SPIFFE Verifiable
    Identity Documents (SVIDs) including X.509-SVIDs and JWT-SVIDs, as well as trust bundle updates. It enables software to
    obtain cryptographic identities at runtime without requiring secrets to be embedded in configuration or code.

  description: The SPIFFE X.509 SVID (SPIFFE Verifiable Identity Document) is a standard for encoding SPIFFE identities into
    X.509 certificates. The Subject Alternative Name field carries the SPIFFE ID URI, enabling mutual TLS authentication between
    workloads using standard X.509 certificate validation libraries.

    are used in scenarios where X.509 certificates are not practical, such as HTTP header-based authentication between services
    or for passing identity across trust domain boundaries.
