shankar0123 a849c8b8cf fix(security): close BUNDLE 2 — safe first run, demo mode, agent bootstrap
Bundle 2 closure (2026-05-12 acquisition diligence audit). Closes the
"docker compose up == accidental production" hazard: pre-Bundle-2 the
base deploy/docker-compose.yml WAS the demo path (AUTH_TYPE=none +
DEMO_MODE_ACK=true + KEYGEN_MODE=server + DEMO_SEED=true + literal
change-me-... placeholder creds), the README claimed "drop the demo
overlay for a clean install", and ENVIRONMENTS.md table documented
auth-type default as api-key — three contradictory stories layered on
the same compose file.

Source findings closed:
  R2 R3 C1 D9 finding-2 S9               (repo audit)
  SEC-H2 SEC-M1 SEC-M3 OPS-M3 LOW-5 HIGH-6 (cowork audit)

Compose split (deploy/docker-compose.yml + deploy/docker-compose.demo.yml):
The base now ships production-shaped — no AUTH_TYPE override, no
KEYGEN_MODE override, no DEMO_MODE_ACK, no DEMO_SEED, no literal
placeholder fallbacks. POSTGRES_PASSWORD / CERTCTL_AUTH_SECRET /
CERTCTL_CONFIG_ENCRYPTION_KEY / CERTCTL_API_KEY / CERTCTL_AGENT_ID
must come from deploy/.env (sample template in deploy/.env.example +
root .env.example). The demo overlay carries the full demo posture
(every env var + every placeholder credential) so the
`-f docker-compose.demo.yml` one-flag flip remains a zero-config
populated-dashboard path.

Fail-closed startup guards (internal/config/config.go::Validate):
Three new gates layered on the existing HIGH-12 demo-mode listen-bind
guard. All three exempt CERTCTL_DEMO_MODE_ACK=true so the demo overlay
keeps working:
  • HIGH-6:  AUTH_SECRET = "change-me-in-production"        → refuse
  • HIGH-6:  CONFIG_ENCRYPTION_KEY = "change-me-32-char..." → refuse
  • LOW-5:   CORS_ORIGINS contains "*"  (CWE-942 + CWE-352) → refuse

Visible DEMO MODE banner (cmd/server/main.go): every boot under
DEMO_MODE_ACK=true now emits a prominent WARN line with a 6-step
production-promotion checklist. The 2026-04-19 incident (a screenshot
run that kept running for three days) drove this; the per-startup
banner makes the posture unmissable in any log scraper.

Agent enrollment doc alignment:
  • docs/reference/configuration.md L83: corrected the non-existent
    URL `POST /api/v1/agents/register` to the real route
    `POST /api/v1/agents`; added the bootstrap-token note and the
    install-agent.sh handoff sequence.
  • docs/reference/architecture.md L154: replaced "agents register
    themselves at first heartbeat" (false — cmd/agent/main.go fail-
    fasts when CERTCTL_AGENT_ID is unset) with the actual two-step
    operator-driven flow (REST or GUI registration first, returned ID
    fed to install-agent.sh second).

Tests + CI guard:
  • 9 new TestValidate_Bundle2_* cases in internal/config/config_test.go
    covering: placeholder-secret refused + demo-ack exempt; placeholder
    encryption-key refused + demo-ack exempt; real key not mistaken for
    placeholder; wildcard CORS refused + demo-ack exempt; wildcard mixed
    into a concrete allowlist still refused; concrete allowlist accepted.
  • scripts/ci-guards/B2-compose-base-no-demo-env.sh: greps the base
    compose for any of the demo-mode env vars + placeholder credentials.
    Comments stripped before checking so the narrative header in the
    base file can still reference the overlay's posture in prose.

Cold-DB CI smoke (.github/workflows/ci.yml::cold-db-compose-smoke):
Switched to layering -f docker-compose.demo.yml on top of the base —
the new production base requires real env vars the smoke doesn't have,
and the smoke's purpose (catch migration-on-cold-DB regressions + the
bootstrap-token mint path) is orthogonal to which auth posture the
boot lands in.

Remaining operator warnings (not blocking; tracked in CLAUDE.md
"Open decisions"):
  • The first `docker compose -f docker-compose.yml up -d` against a
    pre-Bundle-2 .env (placeholder values still in place) will now
    fail-fast. This is the intended posture but operators upgrading
    from v2.0.x via .env-from-old-master need to rotate before
    upgrading. The CHANGELOG note for the v2.1.0 release should
    call this out alongside Auth Bundle 2's other breaking changes.

# certctl — Self-Hosted Certificate Lifecycle Platform
[![License](https://img.shields.io/badge/license-BSL%201.1-blue.svg)](LICENSE)
[![Go Report Card](https://goreportcard.com/badge/github.com/certctl-io/certctl)](https://goreportcard.com/report/github.com/certctl-io/certctl)
[![GitHub Release](https://img.shields.io/github/v/release/certctl-io/certctl)](https://github.com/certctl-io/certctl/releases)
[![GitHub Stars](https://img.shields.io/github/stars/certctl-io/certctl?style=flat&logo=github)](https://github.com/certctl-io/certctl/stargazers)
certctl is a self-hosted platform that automates the entire TLS certificate lifecycle, from issuance through renewal to deployment, with zero human intervention. Twelve native CA connectors plus an OpenSSL / shell-script adapter for custom CAs; fifteen native deployment-target connectors plus a proxy-agent pattern for network appliances and agentless targets. Private keys stay on your infrastructure where they belong. Free, source-available under BSL 1.1, covers the same lifecycle that enterprise platforms charge $100K+/year for.
The CA/Browser Forum's [Ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) caps public TLS certificates at **200 days by March 2026**, **100 days by 2027**, and **47 days by 2029**. At 47-day lifespans, a team managing 100 certificates is processing 7+ renewals per week, every week, forever. Manual workflows stop being a choice.
> **Status: Early-access — actively looking for design partners.**
> The certificate lifecycle core is production-quality today: Local CA, ACME, agent deployment, audit, [role-based access control](docs/operator/rbac.md) with auditor split and four-eyes approval. v2.1.0 adds federated identity on top — [OIDC SSO](docs/operator/oidc-runbooks/index.md), server-side sessions, back-channel logout, and a break-glass admin path for SSO-outage recovery.
> If your team runs PKI infrastructure that could use real automation, we'd love to have you on certctl. Lab and dev deployments are great. Production is welcome too — especially on the federated-identity surface, where real-world IdP shapes are exactly the exposure we can't manufacture in CI. Battle-testing certctl in your environment is genuinely valuable to us.
> [File issues](https://github.com/certctl-io/certctl/issues) liberally. Every IdP quirk, every connector edge, every doc gap you hit — that's how the platform earns the right to drop the "early-access" label. The faster the loop, the faster everyone benefits.
> **Actively maintained, shipping weekly.** [Open an issue](https://github.com/certctl-io/certctl/issues) if something breaks. CI runs the full test suite with race detection, static analysis, and vulnerability scanning on every commit.

## Why certctl
Certificate lifecycle tooling has historically split into two camps. Enterprise platforms charge six-figure annual licenses, take months to deploy, and bill professional-services hours at $250 to $400 per hour to write integration code that should ship with the product. Single-purpose tools handle one slice of the problem and leave the operator to glue the rest together. certctl fills the gap — full lifecycle automation, self-hosted, free, CA-agnostic, target-agnostic. If you're stitching together cron jobs across a fleet, manually renewing certs, or writing custom integration scripts to bridge a commercial CLM platform to your actual infrastructure, certctl replaces all of that.
Built for **platform engineering and DevOps teams** managing 10 to 500+ certificates, **security teams** who need audit trails and policy enforcement, and **small teams without enterprise budgets** who need enterprise-grade automation for a 50-server environment. For the detailed positioning argument and when not to use certctl, see [Why certctl?](docs/getting-started/why-certctl.md).
## What it does
certctl handles the full certificate lifecycle in one self-hosted control plane:
- **Issue and renew** from any CA. Let's Encrypt and any ACME provider, an embedded ACME server you can point cert-manager / certbot / lego at directly, a built-in local CA with sub-CA mode (chains under your enterprise root like ADCS), step-ca, Vault PKI, EJBCA, AWS ACM PCA, Google CAS, DigiCert, Sectigo, GlobalSign, Entrust, plus an OpenSSL / shell-script adapter for anything custom. Twelve native issuer connectors. See the [connector reference](docs/reference/connectors/index.md).
- **Deploy automatically** to NGINX, Apache, HAProxy, Caddy, Traefik, Envoy, IIS, Windows Cert Store, Java keystore, Kubernetes Secrets, AWS ACM, Azure Key Vault, SSH known-hosts, Postfix + Dovecot, F5 BIG-IP. Fifteen native target connectors. File-based targets share an atomic-write + SHA-256 idempotency + on-failure rollback + per-target Prometheus counters primitive (the `deploy.Apply` path covers 12 of 13 file-based connectors). Cloud / API targets (AWS ACM, Azure Key Vault) use vendor-SDK semantics rather than the file primitive; F5 uses iControl REST transactions; Kubernetes Secrets is preview. For the per-target guarantee matrix, see [`docs/reference/deployment-model.md`](docs/reference/deployment-model.md). The reload / validate commands operators configure for shell-using targets (NGINX, Apache, HAProxy, Postfix, JavaKeystore, SSH) are validated server-side AND agent-side against shell-metacharacter injection before execution (see [`internal/connector/target/configcheck`](internal/connector/target/configcheck)).
- **Run as an ACME server** so existing client tooling plugs in directly. RFC 8555 + RFC 9773 ARI, two per-profile auth modes (public-trust-style validation or trust_authenticated for internal PKI), doubly-signed key rollover, revoke-cert on both kid path and jwk path, per-account rate limiting. Cert-manager / certbot / lego all work pointed at it. See [`docs/reference/protocols/acme-server.md`](docs/reference/protocols/acme-server.md).
- **Run as a SCEP server** for Microsoft Intune-managed phones, ChromeOS devices, network appliances. RFC 8894 native with full PKIMessage wire format, native Intune challenge dispatch with replay protection, per-profile dispatch with separate RA cert per profile. See [`docs/reference/protocols/scep-server.md`](docs/reference/protocols/scep-server.md).
- **Run as an EST server** for HTTPS-based PKCS#10 enrollment. 802.1X / Wi-Fi authentication, IoT device enrollment, RFC 9266 channel binding. See [`docs/reference/protocols/est.md`](docs/reference/protocols/est.md).
- **Manage multi-level CA hierarchies** with name constraints, path-length enforcement, and end-to-end RFC 5280 path validation. Root → intermediate → issuing chains, admin-gated CRUD, drain-first retirement. Patterns documented for 4-level boundary CAs, 3-level policy CAs with per-BU `PermittedDNSDomains`, and 2-level internal PKI. See [`docs/reference/intermediate-ca-hierarchy.md`](docs/reference/intermediate-ca-hierarchy.md).
- **Gate high-stakes issuance** behind two-person-integrity approval. Flag a profile as `RequiresApproval`, the request lands in a queue, a non-requester approves, the scheduler dispatches. Profile-edit changes on approval-tier profiles route through the same gate so the flip-flop bypass is closed. See [`docs/operator/approval-workflow.md`](docs/operator/approval-workflow.md).
- **Authorize with role-based access control.** Seven default roles (admin, operator, viewer, agent, mcp, cli, auditor) over a fine-grained permission catalogue with global / per-profile / per-issuer scope. Auditor role is read-only on the audit trail (`audit.read` + `audit.export`, nothing else) so a regulator's key cannot read certificates or mutate config. Day-0 admin via a one-shot `CERTCTL_BOOTSTRAP_TOKEN` endpoint that closes itself the moment any admin lands. Privilege-escalation guard requires `auth.role.assign` to grant or revoke a role. See [`docs/operator/rbac.md`](docs/operator/rbac.md), [`docs/operator/auth-threat-model.md`](docs/operator/auth-threat-model.md), and the v2.0.x → v2.1.0 [migration guide](docs/migration/api-keys-to-rbac.md).
- **Sign in with OIDC SSO** against any standards-compliant identity provider. Per-IdP setup runbooks for Keycloak, Authentik, Okta, Auth0, Microsoft Entra ID, and Google Workspace. Group-claim → role mapping for automatic provisioning; client_secret encrypted at rest (AES-256-GCM); JWKS auto-refresh on `kid` miss; PKCE-S256 required; RFC 9700 §4.7.1 pre-login UA/IP binding; RFC 9207 `iss` URL-param check on callback. Server mints HMAC-signed session cookies with the `__Host-` prefix (browser-enforced subdomain-takeover defense), CSRF rotation on every privileged write, and idle + absolute expiry. [RFC OIDC Back-Channel Logout 1.0](docs/reference/auth-standards-implemented.md) revokes sessions on IdP-driven logout. Argon2id break-glass admin path for SSO-outage recovery — disabled by default; 404-invisible to scanners when `CERTCTL_BREAKGLASS_ENABLED=false`. See [`docs/operator/oidc-runbooks/index.md`](docs/operator/oidc-runbooks/index.md) for the per-IdP onboarding guides and [`docs/migration/oidc-enable.md`](docs/migration/oidc-enable.md) for enabling SSO on an existing deploy.
- **Discover** existing certs across your fleet via filesystem scanning on agents, network TLS probing across CIDR ranges, and cloud secret manager imports (AWS Secrets Manager, Azure Key Vault, GCP Secret Manager). Triage workflow for claim / dismiss / investigate.
- **Revoke** with full RFC 5280 reason codes, DER CRL generation per issuer (scheduler-pre-generated and ETag-cached), and an embedded RFC 6960 OCSP responder with dedicated per-issuer responder certs. Single + bulk revocation. See [`docs/reference/protocols/crl-ocsp.md`](docs/reference/protocols/crl-ocsp.md).
- **Alert** via Slack, Microsoft Teams, PagerDuty, OpsGenie, email, webhooks. Per-policy multi-channel routing matrix with severity tiers and fault-isolating per-channel dispatch. See [`docs/operator/runbooks/expiry-alerts.md`](docs/operator/runbooks/expiry-alerts.md).
- **Drive the platform from natural language** via the bundled MCP (Model Context Protocol) server. The full REST API is exposed as MCP tools — ask your AI client "show me all expiring certificates", "revoke the VPN cert, key compromised", or "what agents are offline?" and it translates to API calls. Stateless stdio-transport binary at `cmd/mcp-server/`; same auth as the REST API; no extra attack surface. See [`docs/reference/mcp.md`](docs/reference/mcp.md).
## Architecture and security
Go 1.25 control plane with handler → service → repository layering. PostgreSQL 16 backend with idempotent migrations. Pull-only deployment model — the server never initiates outbound connections. Agents poll for work and generate ECDSA P-256 keys locally so private keys never touch the control plane. For network appliances and agentless servers, a proxy agent in the same network zone handles deployment via the target's API (WinRM, iControl REST, SSH/SFTP). See the [Architecture Guide](docs/reference/architecture.md) for full system diagrams.
Security: three authentication paths — API keys (SHA-256 hashed + constant-time compared), [OIDC SSO](docs/operator/oidc-runbooks/index.md) (Keycloak / Authentik / Okta / Auth0 / Entra ID / Google Workspace), and Argon2id [break-glass admin](docs/operator/security.md) for SSO-outage recovery. Successful OIDC login mints an HMAC-signed server-side session with `__Host-` cookies, CSRF rotation on every privileged write, and [RFC OIDC Back-Channel Logout](docs/reference/auth-standards-implemented.md) for IdP-driven session revoke. Role-based authorization on every gated handler with global / per-profile / per-issuer scope. Auditor split keeps regulator-class actors strictly read-only on the audit trail. Day-0 admin via a one-shot bootstrap token; granting or revoking roles requires the dedicated `auth.role.assign` permission. CORS deny-by-default. Shell injection prevention on all connector scripts. SSRF protection (reserved IP filtering) on the network scanner. Issuer + target + OIDC client_secret credentials encrypted at rest with AES-256-GCM. HTTPS-only control plane with TLS 1.3 pinned and a fail-closed startup gate that refuses to boot if the TLS bundle is unusable. Every API call recorded to an immutable audit trail with actor attribution, body hash, and latency tracking. CI runs race detection, static analysis, and vulnerability scanning on every commit. See [`docs/operator/security.md`](docs/operator/security.md) for the full posture and [`docs/operator/auth-threat-model.md`](docs/operator/auth-threat-model.md) for what's defended vs deferred.
## Quick Start
### Docker Compose (recommended)
**Demo path — zero config, populated dashboard:**
```bash
git clone https://github.com/certctl-io/certctl.git
cd certctl
docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.demo.yml up -d --build
```
Wait ~30 seconds, then open **https://localhost:8443** in your browser. The demo overlay flips the base into demo-mode auth (every request served as the synthetic admin actor `actor-demo-anon` — the server emits a prominent ⚠ DEMO MODE banner at boot reminding you this posture is for evaluation only) and seeds 180 days of realistic history across 13 issuers, 8 agents, managed + discovered certs, jobs, deploys, audit, and notification events. The `certctl-tls-init` init container self-signs an ECDSA-P256 cert on first boot — accept the browser warning for the demo, or feed the generated `ca.crt` to your client.
**Production path — `.env` required, fail-closed on placeholders:**
```bash
cp .env.example deploy/.env # or root .env if running outside compose
$EDITOR deploy/.env # set POSTGRES_PASSWORD, CERTCTL_AUTH_SECRET,
# CERTCTL_API_KEY, CERTCTL_CONFIG_ENCRYPTION_KEY,
# CERTCTL_AGENT_ID — all via openssl rand
docker compose -f deploy/docker-compose.yml up -d --build
```
The base compose alone (no demo overlay) ships production-shaped: default `auth-type=api-key`, default `keygen-mode=agent`, no demo seed, no demo-mode synthetic admin. The fail-closed startup guards in `internal/config/config.go::Validate` refuse to boot when any of the change-me-... placeholder credentials reach config outside of demo mode (Bundle 2 closure, 2026-05-12). The four compose files (`docker-compose.yml` base, `docker-compose.demo.yml` overlay, `docker-compose.dev.yml` for PgAdmin + debug logging, `docker-compose.test.yml` for integration tests) are documented at [`deploy/ENVIRONMENTS.md`](deploy/ENVIRONMENTS.md).
```bash
curl --cacert $(docker compose -f deploy/docker-compose.yml exec -T certctl-server cat /etc/certctl/tls/ca.crt) https://localhost:8443/health
# {"status":"healthy"}
```
The control plane is HTTPS-only with TLS 1.3 pinned. See [`docs/operator/tls.md`](docs/operator/tls.md) for cert provisioning patterns.
### Agent install (one-liner)
```bash
curl -sSL https://raw.githubusercontent.com/certctl-io/certctl/master/install-agent.sh | bash
```
Detects your OS and architecture, downloads the binary, configures systemd (Linux) or launchd (macOS), and starts the agent. See [install-agent.sh](install-agent.sh).
### Helm chart (Kubernetes)
```bash
helm install certctl deploy/helm/certctl/ \
--set server.auth.apiKey=your-api-key \
--set postgresql.password=your-db-password
```
Production-ready chart with Server Deployment, PostgreSQL StatefulSet, Agent DaemonSet, health probes, security contexts (non-root, read-only rootfs), and optional Ingress. See [values.yaml](deploy/helm/certctl/values.yaml).
### Container images
```bash
docker pull ghcr.io/certctl-io/certctl-server:latest
docker pull ghcr.io/certctl-io/certctl-agent:latest
```
## Examples
Pick the scenario closest to your setup and have it running in 2 minutes:
| Example | Scenario |
|---------|----------|
| [`examples/acme-nginx/`](examples/acme-nginx/) | Let's Encrypt + NGINX, HTTP-01 challenges |
| [`examples/acme-wildcard-dns01/`](examples/acme-wildcard-dns01/) | Wildcard certs via DNS-01 (Cloudflare hook included) |
| [`examples/private-ca-traefik/`](examples/private-ca-traefik/) | Local CA (self-signed or sub-CA) + Traefik file provider |
| [`examples/step-ca-haproxy/`](examples/step-ca-haproxy/) | Smallstep step-ca + HAProxy combined PEM |
| [`examples/multi-issuer/`](examples/multi-issuer/) | ACME for public + Local CA for internal, one dashboard |
Each directory contains a `docker-compose.yml` and a `README.md` explaining the scenario, prerequisites, and customization.
## Verifying a release
Every `v*` tag publishes signed, attested artefacts (Cosign keyless OIDC + SLSA Level 3 provenance + SPDX-JSON SBOMs). For the verification procedure, see [`docs/reference/release-verification.md`](docs/reference/release-verification.md).
## Development
```bash
make build # Build server + agent binaries
make test # Run tests
make lint # golangci-lint (govet + staticcheck + contextcheck + unused)
govulncheck ./... # Vulnerability scan
make docker-up # Start Docker Compose stack
```
CI runs `go vet`, `go test -race`, `golangci-lint`, `govulncheck`, and per-package coverage thresholds (service 70%, handler 75%, crypto 88%, auth packages 85-95%) on every push. The thresholds-as-data file is `.github/coverage-thresholds.yml`; lowering a floor requires corresponding test work, not a config flip. Frontend CI runs TypeScript type checking, Vitest tests, and Vite production build.
