Archived. The canonical KMS is luxfi/kms (ghcr.io/luxfi/kms). This repository is kept read-only for history, and because sdk/go v1.1.1 is still resolvable from it. Nothing new should depend on it. What follows describes the retired server.

Hanzo KMS

Secrets, keys, and threshold signing for the Hanzo platform — per-org namespaces, IAM-gated, ZAP-native, MPC-backed. A thin Go server over the canonical luxfi/kms primitives.

What this is

Hanzo KMS is the canonical secret store and signing service for every Hanzo deployment. It holds the per-tenant DEKs that back Hanzo Base, the provider API keys the AI and gateway services consume, certificate material, and validator signing keys.

AI agents are first-class identities: every secret carries a policy that controls whether an agent may read it — auto-approve, requires-approval, or blocked — with a full per-agent audit trail.

All server logic lives in luxfi/kms. This module wires those primitives with Hanzo defaults (IAM at hanzo.id, encrypted-at-rest storage, S3 replication) and adds JWT verification, the audit ledger, version CAS, and header hygiene. It builds as its own app (kms.App), which any host composes, and also ships as a standalone daemon.

Quick start

Build from source — pure Go, no database toolchain required:

make kmsd kms          # builds ./kmsd (daemon) and ./kms (admin CLI)
KMS_ENV=dev ./kmsd     # HTTP on :8443, ZAP on :9999

Or run the container image (pin a released tag — never :latest):

docker run -p 8443:8443 ghcr.io/hanzoai/kms:vX.Y.Z

In any non-dev environment the daemon refuses to boot without full JWT config (KMS_EXPECTED_ISSUER, KMS_EXPECTED_AUDIENCE, KMS_JWKS_URL) — fail-closed by design.

AI access control

Your secrets, your rules. AI agents are first-class citizens — and so is your ability to block them.

• Per-secret policies — mark any secret requires-approval; a read from any agent triggers a real-time approval prompt.
• Auto-approve mode — move fast in development, escalate specific secrets to manual sign-off before production.
• Identity tracking — see exactly which model, tool, or agent accessed which secret, and when.
• Full audit trail — every AI-originated read is logged with agent identity, timestamp, and reason.

Secret: STRIPE_LIVE_KEY
  policy:  requires-approval
  reader:  agent via hanzo-mcp
  status:  waiting for approval → [approve] [deny]

API surface

Everything is served under /v1/kms — one canonical path per operation, no aliases, no /api/. Every endpoint requires a Hanzo IAM JWT (RS/ES/PS/EdDSA — never HS*, never none) or an explicit admin role.

Group	Endpoints
Auth	POST /v1/kms/auth/login — machine-identity client credentials → IAM token
Secrets (per-org)	GET / POST / PATCH / DELETE /v1/kms/orgs/{org}/secrets/… — env is a first-class key component; writes require an explicit env; PATCH requires version CAS via If-Match
MPC keys	POST /v1/kms/keys/generate · /{id}/sign · /{id}/rotate · GET /v1/kms/keys · /v1/kms/status — threshold BLS / round signing via luxfi/mpc
Health	GET /healthz — liveness, no auth

A sub-100µs binary ZAP transport (default :9999) mirrors the HTTP surface for in-cluster callers under the identical JWT + role model. The Go client at sdk/go (HTTP with ZAP fallback) is what every other Hanzo service uses to fetch secrets at runtime.

Storage & durability

• At rest — ZapDB (LSM) at $KMS_DATA_DIR; per-secret 256-bit DEK wrapped under the master key (AES-256-GCM).
• Replication — age-encrypted incremental + snapshot backups streamed to S3 (off when unset).
• Audit — buffered SQLite side-table; single writer, never blocks the request path.

Specs

• HIP-0027 — KMS
• HIP-0106 — Unified Cloud Binary (kms subsystem)
• HIP-0302 — Encrypted SQLite + ZapDB durability (DEK source)
