Final PR in the six-commit M-2 sequence (PR-A: CertificateService cluster
cdc9d03, PR-B: IssuerService+TargetService eb14236, PR-C: Policy/Profile/
Owner/Team 2497be4, PR-D: Job/Notification/Audit ccd89c3, PR-E: AgentService
283ec27, PR-F: this commit). PR-A through PR-E collapsed the service-layer
shim methods and deleted every in-production context.Background() /
context.TODO() call from internal/service/; this PR completes the sweep
across the non-service tiers (HTTP middleware + ACME connector) and wires
the contextcheck linter so regressions fail CI.
Three narrow edits land the D-3 pattern (context.WithoutCancel for
subsidiary async writes and deferred shutdown contexts):
- internal/api/middleware/audit.go -- async audit goroutine now runs
on auditCtx := context.WithoutCancel(r.Context()) instead of
context.Background(). Preserves request-scoped values (trace ID, auth)
while detaching from the request's cancellation so the audit write
does not get killed when the response completes. Goroutine is still
tracked via a.wg (M-1 shutdown drain) so Flush(ctx) behaviour is
unchanged. CWE-770 Missing Release (goroutine leak potential) +
CWE-400 Resource Exhaustion (missed cancellation propagation).
- internal/api/middleware/middleware.go -- Recovery panic path now
logs via slog.ErrorContext(ctx, ...) instead of log.Printf. Request-
scoped trace/auth metadata now carries through the panic log, matching
every other request log. D-3 non-bypass: the context is r.Context()
captured before the defer, so even a panic mid-handler propagates
the ctx's trace ID into the ERROR log line.
- internal/connector/issuer/acme/acme.go (HTTP-01 challenge server
shutdown) -- defer shutdown context derived from
context.WithTimeout(context.WithoutCancel(ctx), 5s) instead of
context.Background(). Preserves parent ctx values, detaches from
parent cancellation so Shutdown always gets its full 5-second
budget even when the parent was cancelled. Matches the same pattern
applied in ACME's solveAuthorizationsDNS01 and solveAuthorizationsDNSPersist01.
Linter wiring: .golangci.yml adds `contextcheck` to the enabled set.
golangci-lint v2.11.4 now fails CI on any function that takes a
context.Context parameter but calls into context.Background() or
context.TODO() instead of propagating -- regression guard for all five
prior PRs.
Verification (CI parity, GOCACHE=/tmp/gocache GOMODCACHE=/tmp/gomodcache
GOLANGCI_LINT_CACHE=/tmp/lintcache):

Wire-format invariants preserved: 0 API routes, 0 SQL migrations, 0
frontend bytes, 0 OpenAPI bytes, 0 connector interface signature changes,
0 new env vars, 0 new external dependencies (pure context stdlib). The
AuditRecorder interface signature, the body-hash algorithm (SHA-256 16

the responseWriter status-capture wrapper, the AuditServiceAdapter, and
all 116 API routes under /api/v1/, /.well-known/est/, /scep, /health,
/auth are byte-identical.

Audit complete. Commit: 1f6cf0eafa. Sections: 12. Findings: 2/7/10/4/6.
loadCAFromDisk now validates the upstream sub-CA certificate's NotBefore
and NotAfter fields before accepting it, returning a fail-closed error
at server startup instead of silently loading an out-of-window CA.
Before this fix, loadCAFromDisk checked BasicConstraints.IsCA and
KeyUsage=CertSign but not the validity window. An expired enterprise
sub-CA (e.g. an ADCS subordinate whose rollover slipped) would load
without warning and the scheduler would mint child certs that every
RFC 5280 path validator rejects — outages show up at relying parties,
not at certctl, and only after thresholds trip.
CWE-672 (Operation on a Resource after Expiration or Release); secondary
CWE-295 (Improper Certificate Validation). Error strings include the CA
subject CommonName and both RFC3339 timestamps so the log line is
actionable in a 3am incident.
Tests: TestSubCAMode gains three subtests exercising the new gate —
SubCA_ExpiredCert_IsRejected (CA expired 1h ago → error mentions
'expired' and the CN), SubCA_NotYetValid_IsRejected (CA valid +1h →
error mentions 'not yet valid' and the CN), and SubCA_BarelyValid_IsAccepted
(CA valid [now-1m, now+1h] → issuance succeeds, proving no
over-rejection). Adds generateTestSubCAWithValidity helper; the
original generateTestSubCA wrapper preserves the [now, now+5y] default
for existing tests.
Package coverage: 67.7% -> 68.3%.
Verification: go build, go vet, go test -race, go test -cover all
green locally; golangci-lint v2.11.4 clean; govulncheck clean. All CI
coverage floors met with margin (service 67.6/55, handler 78.6/60,
domain 92.7/40, middleware 80.0/30, crypto 86.7/85).
Parent: 5abeeb8 (M-8 per-ciphertext salt).
Closes: audit finding M-5 in certctl-audit-report.md.
The GlobalSign Atlas HVCA connector previously used InsecureSkipVerify:true
on its mTLS TLS config, disabling server certificate validation and
defeating the purpose of the client-side mTLS handshake. This was a
CWE-295 Improper Certificate Validation vulnerability silently degrading
trust on every production call to GlobalSign's signing API.
Remediation (per H-5 audit finding, Lens 4.4):
- Remove InsecureSkipVerify from all three http.Client construction sites
(ValidateConfig, getHTTPClient, and legacy initialisation path).
- Introduce buildServerTLSConfig() helper that constructs tls.Config with
MinVersion: tls.VersionTLS12 (addresses adjacent L-1 recommendation).
- New optional config field `server_ca_path` (env:
CERTCTL_GLOBALSIGN_SERVER_CA_PATH). When unset the connector trusts the
system root CA bundle (correct default for GlobalSign's publicly-trusted
HVCA endpoints). When set the bundle is loaded via x509.NewCertPool() +
AppendCertsFromPEM, and only those roots are trusted (supports private
HVCA deployments and defence-in-depth root pinning).
- Error wrapping chain: "failed to read server CA bundle at %s" and
"no valid PEM certificates found in server CA bundle at %s" surface
config problems at ValidateConfig time instead of silently failing at
request time.
Docs, config, service env-seed, and GUI issuer type definition updated to
expose the new field. Tests: 9 dead `InsecureSkipVerify: true` client
TLSClientConfig blocks (no-ops against httptest.NewServer plain-HTTP)
replaced with bare http.Client; new TestGlobalSign_ServerTLSConfig covers
pinned-CA trust, untrusted-server rejection, missing-file and invalid-PEM
error paths.
Verification:
- go build ./... clean
- go vet ./... clean
- go test -race ./internal/connector/issuer/globalsign/... ./internal/config/... ./internal/service/... ok
- go test ./... (excluding testcontainers-gated repo layer) ok
- golangci-lint run ./... 0 issues
- govulncheck ./... 0 reachable vulns
- Per-layer coverage: service 68.7% (≥55), handler 83.6% (≥60), domain 82.0% (≥40), middleware 63.8% (≥30)
- globalsign package coverage: 75.9%
- Invariant sweep: 0 InsecureSkipVerify references remain in globalsign
package (only a test-file comment documenting the removal).
Add three new issuer connectors completing commercial and open-source CA
coverage. Entrust uses mTLS client certificate auth with sync/async
issuance. GlobalSign Atlas uses mTLS + API key/secret dual auth with
serial-based tracking. EJBCA supports dual auth (mTLS or OAuth2) for
self-hosted Keyfactor CAs.
Each connector implements the full issuer.Connector interface (9 methods),
includes httptest-based unit tests (~14 each), and follows established
patterns (injectable HTTP clients, RFC 5280 revocation reason mapping,
CRL/OCSP delegated to CA).
Also includes: issuer factory cases, env var seeding, config structs,
domain types, seed data (3 rows, all disabled), OpenAPI enum updates,
frontend issuer catalog entries with config fields, and full docs
(connectors.md, architecture.md, features.md, README).

Enforce certificate profile crypto constraints across all 5 issuance paths
(renewal, agent CSR, EST, SCEP). ValidateCSRAgainstProfile() rejects CSRs
with key algorithm/size that don't match profile rules. MaxTTL enforcement
caps certificate validity per issuer connector (Local CA, Vault, step-ca
enforce directly; ACME/DigiCert/Sectigo pass through). Key algorithm and
size are now persisted in certificate_versions for audit compliance.
16 new tests (12 service-layer + 4 Local CA connector). Removes hardcoded
version number from GUI sidebar. Documentation updated across architecture,
features, connectors, and README.

Close coverage gaps identified by dual-audit (qualitative + quantitative).
New test files for config (0%→98%), router (0%→100%), handler validation,
health, audit, response helpers, webhook notifier (0%→88%), email notifier,
middleware (recovery, rate limiter), domain profile, service nil-safety,
config helpers, issuer bootstrap, and server bootstrap wiring. Expanded
existing tests for ACME (34%→42%), step-ca (42%→52%), F5, SSH, agent
(43%→63%), scheduler (88%→99%), renewal service, and issuerfactory.
All tests pass: go test -short, go vet, go test -race clean.

Three related ACME ecosystem changes shipped as a single milestone:
1. ACME Certificate Profile Selection: Custom JWS-signed newOrder POST with
`profile` field (e.g., `tlsserver`, `shortlived` for 6-day certs) bypassing
acme.Client.AuthorizeOrder() since golang.org/x/crypto lacks profile support.
ES256 JWS signing with kid mode, nonce management, directory discovery.
Empty profile delegates to standard library path (zero behavior change).
Configurable via CERTCTL_ACME_PROFILE env var. GUI: profile dropdown on
ACME issuer config.
2. ARI RFC 9702 → 9773 Renumber: All 25+ references updated across Go source,
docs, README, and examples. Zero remaining occurrences of RFC 9702.
3. 45-Day / Short-Lived Certificate Positioning: 5 domain tests validating
renewal thresholds against SC-081v3 validity reduction timeline (200→100→47
days) and Let's Encrypt 45-day/6-day profiles. ARI (RFC 9773) is the
expected renewal path for 6-day shortlived certs.
New tests: 13 profile + 5 domain threshold + 1 frontend = 19 new tests.

Replace static env-var-based issuer wiring with GUI-driven dynamic
configuration stored encrypted in PostgreSQL. Operators can now
configure, test, enable/disable, and manage issuers from the dashboard
without restarting the server.
Key changes:
- AES-256-GCM encryption for sensitive issuer config at rest (PBKDF2
key derivation with 100k iterations)
- Dynamic IssuerRegistry with sync.RWMutex replacing static map
- Connector factory pattern (issuerfactory.NewFromConfig) replacing
140 lines of static wiring in main.go
- Migration 000009: encrypted_config, last_tested_at, test_status,
source columns on issuers table
- Env var seeding on first boot with ON CONFLICT DO NOTHING
- Registry Rebuild() for atomic map swap after CRUD operations
- Issuer type validation against domain constants on Create
- Audit trail for test connection results
- Conditional seeding for step-ca/OpenSSL (only when env vars set)
- GUI: source badge, connection test status on issuer detail page

Fixes 12 production bugs preventing the full issuance→deployment flow
from working with ACME (Pebble/Let's Encrypt) and step-ca issuers:
ACME connector (acme.go):
- Save orderURI before WaitOrder overwrites it (Go crypto/acme bug)
- Add CreateOrderCert fallback via WaitOrder+FetchCert
- Remove defer-reset in ValidateConfig that caused nil pointer panic
- Add Insecure TLS option for self-signed ACME servers (Pebble)
step-ca connector (stepca.go, jwe.go):
- Real JWE provisioner key loading + decryption (was using ephemeral keys)
- Fix JWT audience (/1.0/sign), sha claim (key fingerprint), kid header
- Custom root CA trust via RootCertPath config
- Remove hardcoded 90-day validity default (let step-ca decide)
NGINX target connector (nginx.go):
- Use sh -c for validate/reload commands (shell interpretation)
- Use filepath.Dir instead of fragile string slicing
- Add private key file writing (agent-mode keys were never deployed)
- Make chain_path write conditional
Server/service layer:
- TriggerRenewalWithActor now creates actual Job records (was no-op)
- createDeploymentJobs falls back to DB query when cert.TargetIDs empty
- ProcessPendingJobs skips agent-routed deployment jobs
- Agent cert pickup path parsing: len(parts)<4 → len(parts)<3
- Health/ready/auth-info endpoints bypass auth middleware
- Write timeout 15s→120s for ACME issuance
- Cert fingerprint computed on CSR submission
Integration test environment (deploy/test/):
- 10-phase test script covering Local CA, ACME, step-ca, revocation,
discovery, renewal, and API spot checks
- Docker Compose with 7 containers (server, agent, postgres, nginx,
pebble, challtestsrv, step-ca) on isolated network
- TLS verification checks SAN (not just Subject CN) for modern CA compat

Add certificate export in PEM (JSON or file download) and PKCS#12 formats.
Private keys are never included — they stay on agents. Add EKU-aware
issuance threading profile EKUs (serverAuth, clientAuth, codeSigning,
emailProtection, timeStamping) through the full issuance pipeline. Fix
agent CSR SAN splitting for email addresses, adaptive KeyUsage flags for
S/MIME vs TLS, and a pre-existing generateID collision bug in deployment
job creation.

- Updated AgentService interface to accept context.Context parameter in all methods
- Replaced context.Background() calls with proper ctx parameter in agent.go
- Updated AgentGroupService interface to accept context.Context parameter
- Replaced context.Background() calls with proper ctx parameter in agent_group.go
- Updated handler methods to pass r.Context() to service methods
- Context now properly propagates through request lifecycle for timeout/cancellation
- Improved request tracing and cancellation behavior
EAB credentials (KID + HMAC) were defined in the ACME connector config
but never wired into the acme.Account registration call. This fixes the
dead code and adds automatic EAB credential fetching for ZeroSSL — when
the directory URL is detected as ZeroSSL and no EAB credentials are
provided, certctl calls ZeroSSL's public API to get them automatically.
Changes:
- Wire EABKid/EABHmac into acme.Account.ExternalAccountBinding
- Add isZeroSSL() detection and fetchZeroSSLEAB() auto-fetch
- Add CERTCTL_ACME_EAB_KID/CERTCTL_ACME_EAB_HMAC env vars to main.go
- Add 13 ACME connector tests (config validation, EAB decode, ZeroSSL
auto-EAB with mock servers, URL detection)
- Update docs: README, architecture, connectors, demo-advanced,
testing-guide with EAB/auto-EAB documentation

Standing TXT record at _validation-persist.<domain> eliminates per-renewal
DNS updates. Auto-fallback to dns-01 if CA doesn't offer dns-persist-01.
ScriptDNSSolver extended with PresentPersist method. Configurable via
CERTCTL_ACME_CHALLENGE_TYPE=dns-persist-01 and
CERTCTL_ACME_DNS_PERSIST_ISSUER_DOMAIN env vars.
Also fixes IsExpired edge-case test in discovery_test.go that always failed
due to time.Now() drift between test setup and method invocation.

Implement Enrollment over Secure Transport protocol with 4 endpoints under
/.well-known/est/ — cacerts (CA chain distribution), simpleenroll (initial
enrollment), simplereenroll (certificate renewal), and csrattrs (CSR
attributes). PKCS#7 certs-only wire format with hand-rolled ASN.1, accepts
both PEM and base64-encoded DER CSRs, configurable issuer and profile
binding, full audit trail. 28 new tests (18 handler + 10 service).
Also includes:
- GetCACertPEM added to issuer connector interface (all 4 issuers updated)
- EST integration tests wired into e2e test suite (13 test cases)
- QA testing guide Part 26 (15 manual EST test cases)
- All docs updated: README, features, architecture, concepts, connectors,
quickstart, demo-advanced (endpoint counts, MCP wording, agent IDs,
issuer interface, resource lists, OpenSSL status)

Upgrade from Go 1.22 to 1.25 (minimum for MCP SDK, actively supported).
CI updated to match.
Codebase audit fixes:
- Local CA parseIP() now uses net.ParseIP — IP SANs no longer silently dropped
- Nil pointer guards in agent.go GetWorkWithTargets for target/cert enrichment
- MCP CreateCertificateInput marks owner_id/team_id as required
- NGINX connector uses CombinedOutput() — captures diagnostic output on failure
- Jobs handler validates JSON decode on rejection body — returns 400 on malformed
- CRL/OCSP handlers propagate requestID for error tracing
MCP server tests (26 tests):
- client_test.go: HTTP client coverage (GET/POST/PUT/DELETE, auth, 204, errors, binary)
- tools_test.go: tool registration, pagination, end-to-end flows with mock API

Backend:
- Embedded OCSP responder: GET /api/v1/ocsp/{issuer_id}/{serial} returns
signed OCSP responses (good/revoked/unknown) using CA key
- DER-encoded X.509 CRL: GET /api/v1/crl/{issuer_id} returns proper DER CRL
signed by issuing CA with 24h validity window
- Short-lived cert exemption: certs with profile TTL < 1 hour skip CRL/OCSP
(expiry is sufficient revocation for ephemeral workloads)
- Extended issuer connector interface with GenerateCRL and SignOCSPResponse
- Local CA implements full CRL/OCSP signing; ACME and step-ca return
appropriate "use native endpoint" errors
- IssuerConnectorAdapter bridges new methods between layers
Frontend:
- Revoke button on certificate detail page with RFC 5280 reason modal
- Revocation banner with reason display and timestamp
- Revocation status indicators in lifecycle section
- "Revoked" filter option in certificates list
- API client: revokeCertificate() function and Certificate type extensions
Tests: ~31 new tests across connector, service, handler, and adapter layers
Docs: milestones renumbered (M13-M14, M16-M18), M15b marked complete

Sub-CA mode: Local CA loads CA cert+key from disk (CERTCTL_CA_CERT_PATH +
CERTCTL_CA_KEY_PATH) to operate as subordinate CA under enterprise root
(e.g., ADCS). Supports RSA, ECDSA, PKCS#8 keys. Validates IsCA and
KeyUsageCertSign. Falls back to self-signed when paths unset.
DNS-01 challenges: Pluggable DNSSolver interface with script-based hook
implementation. User-provided scripts create/cleanup _acme-challenge TXT
records for any DNS provider. Configurable propagation wait. Enables
wildcard certs and non-HTTP-accessible hosts.
step-ca connector: Smallstep private CA via native /sign API with JWK
provisioner auth. Issuance, renewal, revocation. Registered as iss-stepca.
23 new tests across 3 files. CI test path widened to ./internal/connector/issuer/...
