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.
