About:
SPIFFE Helper is a command-line utility that acts as a sidecar to simplify the retrieval and management of SVIDs (SPIFFE Verifiable Identity Documents) for workloads. It automatically handles the rotation of certificates and keys by communicating with the SPIFFE Workload API, ensuring secure and continuous identity management. This tool allows applications to remain agnostic of the underlying SPIFFE implementation details.

Key Features:

Automates SVID retrieval via the Workload API
Manages automatic certificate and key rotation
Supports writing SVIDs to disk for legacy applications
Lightweight sidecar architecture

Use Cases:

Providing mTLS certificates to web servers or microservices
Enabling legacy applications to use SPIFFE identities without code changes
Automating secret rotation for secure service-to-service communication

Alternatives:

SPIRE Agent – SPIRE Agent provides core workload attestation and API serving; spiffe-helper is a companion tool specifically focused on SVID retrieval and filesystem management for applications.
