SPIRE (the SPIFFE Runtime Environment) is a toolchain of APIs for establishing trust between software systems across a wide variety of hosting platforms. SPIRE exposes the SPIFFE Workload API, which can attest running software systems and issue SPIFFE IDs and SVIDs to them. This in turn allows two workloads to establish trust between each other, for example by establishing an mTLS connection or by signing and verifying a JWT token. SPIRE can also enable workloads to securely authenticate to a secret store, a database, or a cloud provider service.
SPIRE 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.
For supported integration versions, see Supported Integrations.
The SPIFFE community maintains the SPIRE project. Information on the various SIGs and relevant standards can be found in https://github.com/spiffe/spiffe.
A third party security firm (Cure53) completed a security audit of SPIFFE and SPIRE in February of 2021. Additionally, the CNCF Technical Advisory Group for Security conducted two assessments on SPIFFE and SPIRE in 2018 and 2020. Please find the reports and supporting material, including the threat model exercise results, below.
