Production Phase

The Secure Production Identity Framework For Everyone (SPIFFE) Project defines a framework and set of standards for identifying and securing communications between application services. At its core, SPIFFE is:

  • A standard defining how services identify themselves to each other. These are called SPIFFE IDs and are implemented as Uniform Resource Identifiers (URIs).

  • A standard for encoding SPIFFE IDs in a cryptographically-verifiable document called a SPIFFE Verifiable Identity Document or SVIDs.

  • An API specification for issuing and/or retrieving SVIDs. This is the Workload API.

The SPIFFE Project has a reference implementation, the SPIRE (the SPIFFE Runtime Environment), that in addition to the above, it:

  • Performs node and workload attestation.

  • Implements a signing framework for securely issuing and renewing SVIDs.

  • Provides an API for registering nodes and workloads, along with their designated SPIFFE IDs.

  • Provides and manages the rotation of keys and certs for mutual authentication and encryption between workloads.

  • Simplifies access from identified services to secret stores, databases, services meshes and cloud provider services.

  • Interoperability and federation to SPIFFE compatible systems across heterogeneous environments and administrative trust boundaries.

SPIFFE is a graduated project of the Cloud Native Computing Foundation (CNCF). If you are an organization that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF.

SPIFFE Standards

Getting Started

  • spiffe: This repository includes the SPIFFE ID, SVID and Workload API specifications, example code, and tests, as well as project governance, policies, and processes.
  • spire: This is a reference implementation of SPIFFE and the SPIFFE Workload API that can be run on and across varying hosting environments.
  • go-spiffe: Golang client libraries.
  • java-spiffe: Java client libraries



SIGs & Working Groups

Most community activity is organized into Special Interest Groups (SIGs), time-bounded working groups, and our monthly community-wide meetings. SIGs follow these guidelines, although each may operate differently depending on their needs and workflows. Each group's material can be found in the /community directory of this repository.

The SPIFFE Steering Committee meets on a regular cadence to review project progress, address maintainer needs, and provide feedback on strategic direction and industry trends. Community members interested in joining this call can find details below.
