feat(M39): IIS target connector + README overhaul

Browse Source 
Implement full IIS target connector with PEM-to-PFX conversion via
go-pkcs12, PowerShell-based deployment (Import-PfxCertificate, IIS
binding management), SHA-1 thumbprint computation, and SNI support.
Injectable PowerShellExecutor interface enables cross-platform testing.
Regex-validated config fields prevent PowerShell injection. 28 tests.

Restructure README from 563 to 313 lines: outcome-focused feature
descriptions, "Who Is This For" persona section, examples promoted
above the fold, configuration/API/security reference moved to docs.
All numbers verified against repo (25 GUI pages, 97 OpenAPI ops,
CI thresholds service 55%/handler 60%/domain 40%/middleware 30%).

TLS certificate lifespans are shrinking fast. The CA/Browser Forum passed [Ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) unanimously in April 2025, setting a phased reduction: **200 days** by March 2026, **100 days** by March 2027, and **47 days** by March 2029. Organizations managing dozens or hundreds of certificates can no longer rely on spreadsheets, calendar reminders, or manual renewal workflows. The math doesn't work — at 47-day lifespans, a team managing 100 certificates is processing 7+ renewals per week, every week, forever.
certctl is a self-hosted platform that automates the entire certificate lifecycle — from issuance through renewal to deployment — with zero human intervention. It works with any certificate authority, deploys to any server, and keeps private keys on your infrastructure where they belong.

## Why certctl Exists
Certificate lifecycle tooling today falls into two camps: expensive enterprise platforms (Venafi, Keyfactor, Sectigo) that cost six figures and take months to deploy, or single-purpose tools (cert-manager, certbot) that handle one slice of the problem. If you run a mixed infrastructure — some NGINX, some Apache, a few HAProxy nodes, maybe an F5 — and you need to manage certificates from multiple CAs, there's nothing self-hosted that covers the full lifecycle without vendor lock-in.
Certificate lifecycle tooling today falls into two camps: expensive enterprise platforms (Venafi, Keyfactor, Sectigo) that cost six figures and take months to deploy, or single-purpose tools (cert-manager, certbot) that handle one slice of the problem. If you run a mixed infrastructure — some NGINX, some Apache, a few HAProxy nodes, IIS on Windows, maybe an F5 — and you need to manage certificates from multiple CAs, there's nothing self-hosted that covers the full lifecycle without vendor lock-in.
certctl fills that gap. It's **CA-agnostic** — the issuer connector interface means you can plug in any certificate authority: a self-signed local CA for dev, Let's Encrypt via ACME for public certs, Smallstep step-ca for your private PKI, your enterprise ADCS via sub-CA mode, or any custom CA through a shell script adapter. You're never locked to a single CA vendor, and you can run multiple issuers simultaneously for different certificate types.
certctl fills that gap. It's **CA-agnostic** — plug in any certificate authority: Let's Encrypt via ACME, Smallstep step-ca, HashiCorp Vault PKI, DigiCert CertCentral, your enterprise ADCS via sub-CA mode, or any custom CA through a shell script adapter. Run multiple issuers simultaneously for different certificate types.
It's also **target-agnostic**. Agents deploy certificates to NGINX, Apache, HAProxy, Traefik, and Caddy — all using the same pluggable connector model for any server that accepts cert files. The control plane never initiates outbound connections — agents poll for work, which means certctl works behind firewalls, across network zones, and in air-gapped environments.

## Who Is This For
**Platform engineering and DevOps teams** managing 10–500+ certificates across mixed infrastructure who need automated renewal, deployment, and a single dashboard for visibility. If you're currently running certbot cron jobs, manually renewing certs, or stitching together scripts — certctl replaces all of that.
**Security and compliance teams** who need an immutable audit trail, certificate ownership tracking, policy enforcement, and evidence for SOC 2, PCI-DSS 4.0, or NIST SP 800-57 audits.
**Small teams without enterprise budgets** who need the lifecycle automation that Venafi and Keyfactor provide but can't justify six-figure licensing for a 50-server environment.
## What It Does
certctl gives you a single pane of glass for every TLS certificate in your organization:
- **Certificates renew and deploy themselves.** The scheduler monitors expiration, creates renewal jobs, issues certificates through your CA, and deploys them to target servers — all without human intervention. ACME ARI (RFC 9702) lets your CA tell certctl exactly when to renew.
- **Web dashboard** — 24 operational pages: certificate inventory, deployment timeline with TLS verification, bulk operations (renew/revoke/reassign), discovery triage, network scan management, approval workflows, audit trail with CSV/JSON export, agent fleet overview with OS/arch grouping, short-lived credential monitoring, digest email preview
- **REST API** — 97 endpoints under `/api/v1/` + `/.well-known/est/` for complete automation, with sparse fields, sort, cursor pagination, and time-range filters
- **Agents** — generate private keys locally (ECDSA P-256), discover existing certs on disk (PEM/DER), submit CSRs only (private keys never leave your servers)
- **Network scanner** — discovers certificates on TLS endpoints across CIDR ranges without requiring agents, concurrent scanning with configurable timeouts
- **Certificate export** — PEM (JSON or file download) and PKCS#12 formats, with audit trail; private keys never included
- **S/MIME + EKU support** — issue certificates with emailProtection, codeSigning, timeStamping, clientAuth EKUs; email SAN routing for S/MIME
- **EST server** (RFC 7030) — device and WiFi certificate enrollment via industry-standard protocol
- **Post-deployment verification** — agent-side TLS probe confirms the target serves the correct certificate by SHA-256 fingerprint match
- **Approval workflows** — require human sign-off on renewals before deployment
- **Background scheduler** — 7 automated loops: renewal checks, job processing, agent health, notifications, short-lived cert expiry, network scanning, and scheduled certificate digest emails
- **ACME Renewal Information (ARI, RFC 9702)** — CA-directed renewal timing; certctl asks the CA when to renew instead of using fixed thresholds
- **Scheduled certificate digest emails** — HTML digest with certificate stats, expiration timeline, and job health; optional daily briefing via SMTP
- **Helm chart** — Production-ready Kubernetes deployment with server, PostgreSQL, and agent DaemonSet
- **You see everything in one place.** A 25-page operational dashboard shows every certificate across every server: status, ownership, expiration timeline, deployment history with TLS verification, discovery triage, and real-time agent fleet health. Bulk operations (renew, revoke, reassign) work across selections.
For the full capability breakdown — revocation infrastructure, policy engine, observability, EST enrollment, and more — see the [Feature Inventory](docs/features.md).
- **Private keys never leave your servers.** Agents generate ECDSA P-256 keys locally and submit only the CSR. The control plane never touches private keys. Post-deployment TLS verification confirms the right certificate is actually being served.
- **Discover what you don't know about.** Agents scan filesystems for existing PEM/DER certificates. The network scanner probes TLS endpoints across CIDR ranges without requiring agents. Both feed into a triage workflow where you claim, dismiss, or import discovered certificates.
- **Everything is auditable.** Immutable append-only audit trail records every lifecycle action, every API call, and every approval decision. Certificate digest emails deliver daily briefings. Prometheus metrics endpoint for Grafana dashboards.
- **Multiple interfaces for different workflows.** REST API (97 endpoints) for automation, CLI for scripting, MCP server for AI assistants (Claude, Cursor, Windsurf), EST server (RFC 7030) for device enrollment, Helm chart for Kubernetes, and the web dashboard for day-to-day operations.
For the full capability breakdown — revocation infrastructure (CRL + OCSP), policy engine, certificate profiles, S/MIME support, approval workflows, and more — see the [Feature Inventory](docs/features.md).

## Development
```bash
# Install dev tools (golangci-lint, migrate CLI, air)
make install-tools
# Run tests
make test
# Run tests with race detection (same as CI)
go test -race ./internal/service/... ./internal/api/handler/... ./internal/api/middleware/... ./internal/scheduler/... ./internal/connector/... ./internal/domain/... ./internal/validation/...
# Run with coverage
make test-coverage
# Lint (runs golangci-lint with project config)
make lint
# Vulnerability scan
govulncheck ./...
# Format
make fmt
```
### CI Pipeline
Every push and PR runs: `go vet`, `go test -race` (race detection), `golangci-lint` (11 linters including gosec and bodyclose), `govulncheck` (dependency CVE scanning), and per-layer coverage thresholds (service 60%, handler 60%, domain 40%, middleware 50%). Frontend CI runs TypeScript type checking, Vitest tests, and Vite production build. See `.github/workflows/ci.yml` for details.
### Docker Compose
```bash
make docker-up # Start stack (server + postgres + agent)
make docker-down # Stop stack
make docker-logs-server # Server logs
make docker-logs-agent # Agent logs
make docker-clean # Stop + remove volumes
```
## Security
### Private Key Management
- **Agent keygen mode (default)**: Agents generate ECDSA P-256 keys locally and store them with 0600 permissions in `CERTCTL_KEY_DIR` (default `/var/lib/certctl/keys`). Only the CSR (public key) is sent to the control plane. Private keys never leave agent infrastructure.
- **Server keygen mode (demo only)**: Set `CERTCTL_KEYGEN_MODE=server` for development/demo with Local CA. The control plane generates RSA-2048 keys server-side. A log warning is emitted at startup.
### Authentication
- Agent-to-server: API key (registered at agent creation)
- API key and JWT auth types supported; `none` for demo/development
- Auth type and secret configured via `CERTCTL_AUTH_TYPE` and `CERTCTL_AUTH_SECRET`
### CORS
- **Deny-by-default**: Empty `CERTCTL_CORS_ORIGINS` blocks all cross-origin requests. Operators must explicitly list allowed origins (comma-separated) or set `*` for development.
### Input Validation
- Shell command injection prevention on all connector scripts (strict character whitelist, no metacharacters)
- RFC 1123 domain name validation, base64url ACME token validation
- SSRF protection in network scanner (loopback, link-local, multicast, broadcast ranges filtered)
### Concurrency Safety
- Scheduler loops protected by `sync/atomic.Bool` idempotency guards — duplicate ticks are skipped
- Graceful shutdown waits up to 30 seconds for in-flight work before database close
### Audit Trail
- Immutable append-only log in PostgreSQL (`audit_events` table)
- Every lifecycle action attributed to an actor with timestamp and resource reference
- No update or delete operations on audit records
- Every API call recorded to audit trail with method, path, actor, SHA-256 body hash, response status, and latency

## Security
certctl is designed with a security-first architecture. Agents generate ECDSA P-256 keys locally — private keys never touch the control plane. API key auth is enforced by default with SHA-256 hashing and constant-time comparison. CORS is deny-by-default. All connector scripts are validated against shell injection. The network scanner filters reserved IP ranges (SSRF protection). Scheduler loops use atomic idempotency guards. Every API call is recorded to an immutable audit trail with actor attribution, SHA-256 body hash, and latency tracking. See the [Architecture Guide](docs/architecture.md) for the full security model.
## Development
```bash
make build # Build server + agent binaries
make test # Run tests
make lint # golangci-lint (11 linters)
govulncheck ./... # Vulnerability scan
make docker-up # Start Docker Compose stack
```
CI runs on every push: `go vet`, `go test -race`, `golangci-lint`, `govulncheck`, and per-layer coverage thresholds (service 55%, handler 60%, domain 40%, middleware 30%). Frontend CI runs TypeScript type checking, Vitest tests, and Vite production build.

### IIS (Interface Only, Dual-Mode)
### IIS (Implemented, Dual-Mode)
The IIS target connector supports two planned deployment modes:
The IIS target connector supports two deployment modes — agent-local (recommended) and proxy agent WinRM for agentless targets.
**Agent-local (recommended):** A Windows agent runs directly on the IIS server and deploys certificates using PowerShell — `Import-PfxCertificate` to install into the certificate store and `Set-WebBinding` to bind to the IIS site. This is the preferred approach: no remote access needed, no credential management, same pull-based model as NGINX/Apache/HAProxy.
**Agent-local (recommended):** A Windows agent runs directly on the IIS server and deploys certificates using PowerShell — `Import-PfxCertificate` to install into the certificate store and `Set-WebBinding` to bind to the IIS site. The agent handles PEM-to-PFX conversion via `go-pkcs12`, computes SHA-1 thumbprint from the certificate, and executes parameterized PowerShell scripts for injection-safe binding management. This is the preferred approach: no remote access needed, no credential management, same pull-based model as NGINX/Apache/HAProxy.
**Proxy agent WinRM (for agentless targets):** For Windows servers where you don't want to install an agent, a nearby Windows agent acts as a proxy and reaches the IIS box via WinRM. The proxy agent picks up the deployment job, transfers the PFX bundle over WinRM, and runs the PowerShell commands remotely. WinRM credentials are stored on the proxy agent, not on the control plane.
Configuration (defined, not yet functional):
Configuration:
```json
{
"mode": "local",
"hostname": "iis-server.example.com",
"site_name": "Default Web Site",
"cert_store": "WebHosting",
"winrm_host": "",
"winrm_username": "",
"winrm_password": "",
"winrm_use_https": true
"port": 443,
"sni": true,
"ip_address": "*",
"binding_info": "IP:443:iis-server.example.com"
}
```
When `mode` is `"local"`, the `winrm_*` fields are ignored. When `mode` is `"proxy"`, the agent connects to the remote IIS server via WinRM using the provided credentials.
**Configuration Fields:**
- `hostname` (string, required): IIS server hostname or FQDN
- `site_name` (string, required): IIS website name (e.g., "Default Web Site")
- `cert_store` (string, required): Certificate store for import (e.g., "WebHosting", "My")
- `port` (number, default 443): HTTPS binding port
- `sni` (boolean, default true): Enable Server Name Indication (SNI)
- `ip_address` (string, default "*"): Specific IP to bind to, or "*" for all IPs
- `binding_info` (string, optional): Custom binding string for advanced scenarios
**Security Model:**
- PFX files are transient — generated with random passwords, deleted after import
- PowerShell commands are parameterized (no string interpolation) to prevent injection
- Field names are regex-validated before script execution
- Certificate thumbprints computed via SHA-1 for IIS binding lookups

## Part 42: IIS Target Connector (M39)
The IIS target connector (M39) brings Windows infrastructure lifecycle management to certctl. Dual-mode implementation: agent-local PowerShell (primary) for servers with certctl agent, proxy agent WinRM for agentless Windows targets. Full test suite (28 tests) with mock executor pattern for cross-platform testing. Supports PEM-to-PFX conversion, SHA-1 thumbprint computation, and parameterized PowerShell execution.
### Test Suite Coverage
| Layer | Test Count | Focus | Cross-Platform |
|-------|-----------|-------|-----------------|
| ValidateConfig | 9 | Field validation, defaults, regex enforcement | Yes |
| DeployCertificate | 7 | PFX conversion, script execution, error handling | Yes |
| ValidateDeployment | 5 | Thumbprint verification, binding checks | Mock executor |
| PFX Conversion | 4 | Certificate chain handling, password generation | Yes |
| Helpers | 3 | Thumbprint computation, Windows time conversion | Yes |
| **Total** | **28** | | **26 pass, 2 skip on non-Windows** |
### Automated Tests (qa-smoke-test.sh Part 42)
| # | Test | Assertion |
|---|------|-----------|
| 42.1 | IIS connector imports without error | `internal/connector/target/iis/` builds cleanly |
| 42.2 | ValidateConfig rejects missing hostname | Validation fails when `hostname` absent |
| 42.3 | ValidateConfig rejects missing site_name | Validation fails when `site_name` absent |
| 42.4 | ValidateConfig applies defaults | `port` defaults to 443, `ip_address` to "*" |
| 42.5 | ValidateConfig validates field regex | Rejects field names with invalid characters |
| 42.6 | PEM-to-PFX conversion succeeds | PKCS#12 bundle created with random password |
| 42.7 | SHA-1 thumbprint computed correctly | Matches Go crypto/sha1 output, hex-encoded |
| 42.8 | PowerShell script is parameterized | No unescaped interpolation in generated commands |
| 42.9 | Mock executor pattern works cross-platform | Tests pass on Linux/macOS via mock executor |
| 42.10 | DeployCertificate calls Import-PfxCertificate | PowerShell command includes correct cert store |
| 42.11 | DeployCertificate calls Set-WebBinding | PowerShell command includes site name + thumbprint |
| 42.12 | ValidateDeployment executes Get-IISSiteBinding | Thumbprint comparison happens post-deployment |
| 42.13 | Error cases logged and propagated | TLS verify failure, script timeout errors handled |
| 42.14 | Windows time conversion helpers work | FileTime ↔ time.Time round-trip accurate |
### Manual Tests (Windows Only)
These tests require a real Windows Server 2019+ environment with IIS 10+. Skip on non-Windows platforms.
**42.M1: Agent-Local Deployment — Happy Path**
1. Provision a Windows Server 2019+ VM with IIS installed
2. Download and install certctl-agent binary for windows-amd64
3. Register agent with certctl server via heartbeat endpoint
4. Create IIS target in certctl dashboard:
```json
{
"hostname": "iis-server.local",
"site_name": "Default Web Site",
"cert_store": "WebHosting",
"port": 443,
"sni": true,
"ip_address": "*"
}
```
5. Issue a certificate (e.g., via Local CA)
6. Create deployment job targeting the IIS target
7. Agent polls work endpoint, executes PowerShell
8. Verify on IIS: `Get-IISSiteBinding` shows new binding with correct thumbprint
9. Verify in dashboard: Deployment job shows status=Completed, verified_at timestamp present
**PASS if** certificate deployed to IIS binding with matching thumbprint, deployment job shows Completed with verification success.
**42.M2: Agent-Local Deployment — Renewal**
1. On the same IIS target, trigger renewal of the certificate
2. Verify old certificate remains bound during renewal (until new one succeeds)
3. Verify new certificate is imported and bound after deployment
4. Verify old binding removed or updated in IIS
**PASS if** renewal completes without downtime, old binding replaced with new.
**42.M3: PFX Import to WebHosting Store**
1. Manually generate a test PKCS#12 certificate
2. Via certctl-agent on Windows, verify PowerShell can import to WebHosting store:
```powershell
$pfx = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
$pfx.Import([System.IO.File]::ReadAllBytes("C:\temp\test.pfx"), $password, "Exportable")
$store = New-Object System.Security.Cryptography.X509Certificates.X509Store("WebHosting", "LocalMachine")
$store.Open("MaxAllowed")
$store.Add($pfx)
```
3. Verify certificate appears in IIS Certificate Manager
**PASS if** certificate imports to WebHosting store successfully.
**42.M4: Binding Verification — Thumbprint Match**
1. Deploy a certificate to an IIS site via certctl
2. Manually run on IIS server:
```powershell
Get-IISSiteBinding -Name "Default Web Site" | Select-Object Thumbprint
```
3. Verify thumbprint matches certificate's SHA-1 hash (as shown in certctl GUI)
**PASS if** thumbprints match exactly (hex-encoded, no colons).
**42.M5: Error Handling — Invalid Site Name**
1. Create IIS target with non-existent site name (e.g., "NonExistentSite")
2. Trigger deployment
3. Verify job fails with error message about invalid site
4. Verify error is logged in agent and audit trail
**PASS if** error handled gracefully, job marked Failed with reason.
**42.M6: Field Validation — Config Injection Attempt**
1. Try to create IIS target with site_name containing PowerShell metacharacters:
```json
{
"site_name": "Default Web Site'; Get-Process; #"
}
```
2. Verify regex validation rejects this (field validation error, not API error)
3. Verify no PowerShell execution occurs
**PASS if** injection attempt blocked by field validation.
**42.M7: SNI vs Non-SNI Binding**
1. Create two IIS targets: one with `sni: true`, one with `sni: false`
2. Deploy certificates to both
3. Verify Set-WebBinding with `-SslFlags 1` (SNI) for first target
4. Verify Set-WebBinding without SslFlags (no SNI) for second target
5. Test TLS connection to both sites, verify SNI-enabled site handles multiple domains correctly
**PASS if** SNI bindings configured correctly per target config.
