Security Notes

The server defaults to hardcoded FPE keys/tweak and authentication secrets (e.g., 'demo-secret'). It also offers 'authless' and 'debug' authentication modes that bypass security. These are intended for demo/testing and are critical security risks if deployed to production without overriding relevant environment variables (FPE_KEY, FPE_TWEAK, AUTH_TOKEN, AUTH_JWT_SECRET) and configuring AUTH_MODE='production'.
