shankar0123 0161bb201c docs: remove internal engineering docs; docs must be tool- or story-relevant
Operator policy: docs in the public repo must help (a) a user
deploying certctl or (b) the product story. Internal engineering
process documentation belongs in cowork/ scratchpads or in git
commit history, not docs/.

Removed (docs/contributor/, 8 files, 2,323 lines):
  - release-sign-off.md         — internal release-day checklist
  - ci-pipeline.md              — what runs in CI (internal)
  - ci-guards.md                — what the guards are (internal)
  - testing-strategy.md         — internal testing strategy
  - qa-test-suite.md            — internal QA reference (445 lines)
  - qa-prerequisites.md         — internal QA setup
  - gui-qa-checklist.md         — manual GUI QA checklist
  - test-environment.md         — 1,103-line redundant with
                                  docs/getting-started/quickstart.md +
                                  docs/getting-started/advanced-demo.md

Removed supporting script:
  - scripts/qa-doc-seed-count.sh — CI guard for the deleted
                                   qa-test-suite.md seed-data table

Cross-reference cleanup:
  - README.md: dropped the Contributor audience row + footer
    pointer to docs/contributor/.
  - Makefile: dropped `verify-docs` target + qa-stats comment refs.
  - .github/workflows/ci.yml: dropped the QA-doc seed-count drift
    CI step + dead comment refs.
  - docs/reference/cli.md: repointed qa-prerequisites.md → quickstart.md.
  - docs/operator/performance-baselines.md: dropped ci-pipeline.md
    cross-ref.
  - scripts/ci-guards/README.md: dropped the 'Guards explicitly
    NOT here' section that referenced the deleted QA-doc guards.

G-3 env-docs-drift guard improvements (a real consequence: deleting
the contributor docs surfaced that some env vars only had a home
there). Refit the guard to the new doc topology:
  - Defined-scan widened from `config.go + cmd/*` to all of `cmd/ +
    internal/` (production code), excluding `*_test.go` — catches
    service-layer env vars like CERTCTL_STEPCA_ROOT_CERT and
    CERTCTL_ZEROSSL_EAB_URL that were previously invisible to the
    guard.
  - Docs-scan widened to include deploy/ENVIRONMENTS.md (the
    canonical env-var inventory table — should have been in scope
    from day one). Kept narrow to README + docs/ + deploy/helm/ +
    ENVIRONMENTS.md to avoid pulling in compose/test fixtures.
  - ALLOWED filter now applies to both DOCS_ONLY and CONFIG_ONLY
    directions, so dynamic per-profile dispatch surfaces
    (CERTCTL_SCEP_PROFILE_<NAME>_*, CERTCTL_EST_PROFILE_<NAME>_*,
    CERTCTL_QA_*) don't need static doc entries.
  - Added CERTCTL_SCEP_PROFILE_[A-Z_]+ and CERTCTL_EST_PROFILE_[A-Z_]+
    to ALLOWED for the same reason.

deploy/ENVIRONMENTS.md: added CERTCTL_ZEROSSL_EAB_URL row — real
operator override (overrides the ZeroSSL EAB-credentials endpoint;
read at internal/connector/issuer/acme/acme.go:372) that was
defined in Go source but never documented. G-3 caught it after the
defined-scan widened.

scripts/ci-guards/S-1-hardcoded-source-counts.sh: removed dead
WORKSPACE-CHANGELOG.md allowlist entry (the file was deleted in
the prior workspace cleanup).

Verified:
  All 35 scripts/ci-guards/*.sh green (FAIL=0).
  No remaining references to docs/contributor/ or qa-doc-seed-count
  in tracked files.

certctl Documentation

Last reviewed: 2026-05-12

The full docs index, organized by audience. Pick the section that matches what you need to do; each link below opens a focused doc rather than a wall of text.

For the elevator pitch and quickstart commands, see the repo README.md at the root. For the marketing site, see certctl.io.


Getting Started

You're new to certctl, just cloned the repo, or want to understand what it does before installing.

Doc What it covers
Concepts TLS certificates explained for beginners — CAs, ACME, EST, private keys, the full glossary
Quickstart Five-minute setup with Docker Compose, dashboard tour, API tour
Examples Five turnkey scenarios — ACME+NGINX, wildcard DNS-01, private CA+Traefik, step-ca+HAProxy, multi-issuer
Advanced demo End-to-end certificate lifecycle with technical depth at each step
Why certctl Positioning vs ACME clients, agent-based SaaS, enterprise platforms; when to look elsewhere

Reference

You're operating certctl in production or building integrations and need authoritative technical detail.

Doc What it covers
Architecture System design, data flow, security model, deployment topologies
Profiles CertificateProfile policy object — issuer wiring, EKUs, RequiresApproval gate (with profile-edit closure)
API OpenAPI 3.1 spec, integration patterns, client SDK generation
CLI certctl-cli command reference and CI/CD integration patterns
Configuration CERTCTL_* environment variable reference (scheduler, rate limits, deploy verify, audit, agent)
MCP server Model Context Protocol integration for AI assistants
Release verification Cosign / SLSA / SBOM verification procedure
Intermediate CA hierarchy Multi-level CA tree management — RFC 5280 §3.2/§4.2.1.9/§4.2.1.10 enforcement
Auth standards implemented RFC + CWE evidence for the API-key + RBAC + OIDC + sessions + break-glass surface (NOT a compliance-mapping doc)
Deployment model Atomic write, post-deploy verify, rollback semantics across all targets
Vendor matrix Tested vendor versions per target connector

Connectors

The connector index is the canonical catalog (interfaces, registry, scanners, plus an inline reference per built-in). Per-connector deep-dive siblings cover operator-grade material — vendor edges, troubleshooting, rotation playbooks, when-to-use vs alternatives.

Issuers (13 deep-dives): ACME · ADCS · AWS ACM Private CA · DigiCert · EJBCA / Keyfactor · Entrust · GlobalSign Atlas HVCA · Google CAS · Local CA · OpenSSL / Custom CA · Sectigo SCM · step-ca / Smallstep · Vault PKI

Targets (15 deep-dives): Apache · AWS Certificate Manager · Azure Key Vault · Caddy · Envoy · F5 BIG-IP · HAProxy · IIS · Java Keystore · Kubernetes Secrets · NGINX · Postfix / Dovecot · SSH (agentless) · Traefik · Windows Certificate Store

Protocols

Doc What it covers
ACME server Run certctl as an RFC 8555 + RFC 9773 ARI ACME server
ACME server threat model Security posture for the ACME server endpoint
SCEP server RFC 8894 native SCEP server — RA cert config, multi-profile dispatch, must-staple, mTLS sibling route
SCEP for Microsoft Intune Intune-specific deployment guide — NDES replacement playbook
EST server RFC 7030 EST server — 802.1X / Wi-Fi enrollment, IoT bootstrap, channel binding
CRL & OCSP RFC 5280 CRL + RFC 6960 OCSP responder for relying parties
Async CA polling Bounded polling for async-CA issuer connectors

Operator

You're running certctl in production and need operational guidance.

Doc What it covers
Security posture Auth, rate limits, encryption at rest, key rotation, RBAC + OIDC + sessions + break-glass, bootstrap
Secret custody Where private keys live; FileDriver vs HSM/KMS; encryption wire format; env-seeded vs DB-seeded plaintext policy
Observability Metrics surface, Prometheus exposition vs client_golang, tracing scope, log structure, rate-limit semantics across restarts/replicas
RBAC operator reference Roles, permissions, scopes, scope-down + day-0 bootstrap
Auth threat model API-key + RBAC + OIDC + sessions + break-glass — token forgery, session hijacking, IdP compromise, role-grant abuse, bootstrap-token leak, audit-mutation
OIDC / SSO runbooks Per-IdP setup guides — Keycloak, Authentik, Okta, Auth0, Entra ID, Google Workspace
Control plane TLS Self-signed bootstrap, operator-supplied Secret, cert-manager Certificate CR
Database TLS PostgreSQL transport encryption
Approval workflow Two-person integrity gate for high-stakes issuance + profile-edit closure
Helm deployment Kubernetes installation via the bundled chart
Performance baselines Operator-runnable benchmarks for regression spot checks
Auth benchmarks Session + OIDC validation p99 targets and measured baselines
Legacy clients (TLS 1.2) Reverse-proxy runbook for embedded EST/SCEP clients on TLS 1.2

Runbooks

Runbook When
Cloud targets AWS ACM + Azure Key Vault deployment, debugging, rollback
Expiry alerts Per-policy multi-channel routing matrix, severity tiers
Disaster recovery CRL cache, OCSP responder cert, CA private-key rotation, Postgres restore
Config-encryption upgrade Force v1/v2 → v3 re-seal across the database; passphrase rotation procedure
PostgreSQL backup Operator-run backup recipe (docker-compose + Kubernetes); recommended cadence; quarterly DR dry-run
