feat(scep-intune): per-profile dispatcher + SIGHUP reload + per-device rate limit + compliance hook seam
Phase 8 of the SCEP RFC 8894 + Intune master bundle. Wires the internal/scep/intune validator from Phase 7 into the SCEPService dispatch path, with a SIGHUP-reloadable trust anchor holder, a per-(Subject, Issuer) sliding-window rate limiter, and a nil-default ComplianceCheck seam for V3-Pro. Operator-visible surface (per-profile, all default to off): CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_ENABLED=true CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CONNECTOR_CERT_PATH=/etc/certctl/intune.pem CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_AUDIENCE=https://certctl.example.com/scep/corp CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CHALLENGE_VALIDITY=60m CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_PER_DEVICE_RATE_LIMIT_24H=3 Per-profile dispatch (Phase 8.8): an operator running corp-laptops through Intune AND IoT devices through static challenge configures INTUNE_ENABLED=true on the corp profile only — the IoT profile's PKCSReq path skips the dispatcher entirely. Mirrors the per-profile shape established by Phase 1.5. Wire-in surfaces: * config.go (Phase 8.1): SCEPProfileConfig.Intune sub-config of type SCEPIntuneProfileConfig (Enabled/ConnectorCertPath/Audience/ ChallengeValidity/PerDeviceRateLimit24h). Loaded from the indexed CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_* env-var family. Per-profile Validate gate refuses INTUNE_ENABLED=true with empty ConnectorCertPath OR negative PerDeviceRateLimit24h. * cmd/server/main.go (Phase 8.2 + wire-in): preflightSCEPIntuneTrustAnchor helper mirrors preflightSCEPRACertKey/preflightSCEPMTLSTrustBundle shape — fail-loud at boot when the trust anchor file is missing / unreadable / empty / contains an expired cert. The per-profile loop builds the holder + replay cache + rate limiter, calls SetIntuneIntegration on the SCEPService, and starts the SIGHUP watcher. A deferred sweep stops every watcher at shutdown. * internal/scep/intune/trust_anchor_holder.go (Phase 8.5): TrustAnchorHolder mirrors cmd/server/tls.go::certHolder. RWMutex- guarded pool + Reload that swaps a fresh slice on success + WatchSIGHUP goroutine that responds to the same SIGHUP the existing TLS-cert watcher uses. A bad reload (parse error, expired cert) keeps the OLD pool in place so a half-rotation doesn't take Intune enrollment down — same fail-safe pattern. Operators rotate via the on-disk file then 'kill -HUP <certctl-pid>'. * internal/scep/intune/rate_limit.go (Phase 8.6): hand-rolled sliding-window-log limiter keyed by (Subject, Issuer). 100k-entry map cap (matches replay cache); at-cap drops the bucket whose newest timestamp is the oldest. Default 3 enrollments per 24h covers legitimate first-cert + recovery + post-wipe re-enrollment but blocks bulk enumeration from a compromised Connector signing key. maxN <= 0 disables the limiter for tests + the rare operator who wants no per-device cap. Empty subject short-circuits to allow (defense-in-depth: caller's claim validation rejects empty-subject upstream; no shared bucket on ''). Why hand-rolled instead of golang.org/x/time/rate: the rate package is in go.sum as an indirect transitive but not a direct dep. ~30 LoC of stdlib avoids creating a new direct dep. * internal/service/scep.go (Phase 8.3 + 8.4 + 8.7): - SCEPService gains intuneEnabled / intuneTrust / intuneAudience / intuneValidity / intuneReplayCache / intuneRateLimiter / complianceCheck fields. - SetIntuneIntegration() constructor-time injection wires the per-profile state. Profiles with INTUNE_ENABLED=false never call this method, so they pay zero overhead. - SetComplianceCheck() installs the V3-Pro plug-in (see Phase 8.7). - looksIntuneShaped(): JWT-shape pre-check (length > 200 + exactly two dots). Allowed to false-positive (validator catches malformed → ErrChallengeMalformed); MUST NOT false-negative on real Intune challenges. - dispatchIntuneChallenge(): the load-bearing core. Runs ValidateChallenge → CSR-binding via DeviceMatchesCSR → replay cache CheckAndInsert → per-device Allow → optional ComplianceCheck. Each failure leg increments a typed metric label and emits an audit-friendly Warn log line. - PKCSReq + PKCSReqWithEnvelope + RenewalReqWithEnvelope all call dispatchIntuneChallenge first; on outcome.decided=true they either short-circuit (with a typed-error → SCEPFailInfo mapping) or call processEnrollment with action='scep_pkcsreq_intune' (so audit greps can count Intune-vs-static enrollments). - mapIntuneErrorToFailInfo(): typed-error → SCEPFailInfo per RFC 8894 §3.2.1.4.5 (signature/replay/expired → BadMessageCheck; claim-mismatch → BadRequest; default → BadRequest). - intuneFailReason(): typed-error → metric label ('signature_invalid' / 'expired' / 'rate_limited' / etc.). Default 'malformed' so a previously-unseen error category still surfaces in the metric for follow-up. - ComplianceCheck (Phase 8.7): nil-default no-op gate. V3-Pro plugs in via SetComplianceCheck to call Microsoft Graph's compliance API. Returns (compliant, reason, err). nil-err + compliant=false → CertRep FAILURE + 'compliance' reason in audit. err != nil → fail-safe deny (V3-Pro module is responsible for any 'permit on API failure' policy). * internal/service/scep.go also gains parseCSRForIntune() — small private wrapper around encoding/pem + x509 used by the dispatcher for the claim ↔ CSR binding check (separated from the broader processEnrollment because we want to bind BEFORE consuming the replay-cache slot). Tests (gates: ≥85% coverage on intune package, ≥70% on service): * scep_intune_test.go (in internal/service): 14 dispatcher tests covering happy-path Intune enrollment + static-challenge fallback + tampered-challenge reject + claim-mismatch reject + replay detected + rate-limited + compliance-hook nil-default + compliance- hook denies non-compliant + compliance-hook error fails closed + IntuneEnabled accessor + 'no IntuneEnabled = static path unchanged' regression pin + intuneFailReason mapping for every typed error + looksIntuneShaped boundary cases. * trust_anchor_holder_test.go (in internal/scep/intune): NewLoadsBundle, NewRequiresLogger, NewSurfacesLoadError, ReloadHappyPath, ReloadKeepsOldOnFailure, ReloadKeepsOldOnExpired (the fail-safe semantics that make the SIGHUP path operator-friendly), WatchSIGHUPReloadsPool (real SIGHUP to self with poll-for-swap pattern mirroring cmd/server/tls_test.go), WatchSIGHUPStopIsClean (does NOT fire SIGHUP after stop — same caveat as the TLS test: the Go runtime would otherwise terminate the test runner on the next SIGHUP since signal.Stop has removed the handler). * rate_limit_test.go (in internal/scep/intune): AllowsUpToCap, DistinctKeysIndependent, WindowExpiry, DisabledBypass (maxN=0), NegativeCapDisabled, EmptySubjectShortCircuits (defense-in-depth against an empty-subject DoS chokepoint), DefaultCapsHonored, MapCapEvictsOldest (at-cap eviction branch), ConcurrentRaceFree (50 goroutines × 200 inserts), pruneOlderThan + the no-op case. Verification: * gofmt -l on all touched files: clean * go vet ./... : clean * staticcheck on intune/service/config/cmd-server: clean * go test -count=1 -cover ./internal/scep/intune/...: 94.8% (target ≥85%) * go test -short across intune+service+config+handler+cmd-server: all green * G-3 docs-drift CI guard reproduced locally: docs-only filtered= empty, config-only=empty. The new env vars match the existing CERTCTL_SCEP_ allowlist prefix. Refs: cowork/scep-rfc8894-intune-master-prompt.md::Phase 8 cowork/scep-rfc8894-intune/progress.md Constitutional rule: 'Always take the complete path, not the easy path' (cowork/CLAUDE.md::Operating Rules) — operator can flip CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_ENABLED=true and observe the dispatcher pick up Intune-shaped challenges end-to-end with no further code changes.

feat(scep): RenewalReq + GetCertInitial + ChromeOS E2E + caps + must-staple
SCEP RFC 8894 + Intune master bundle — Phase 4 + Phase 5 of 14.
Half 1 of the bundle's two halves is now COMPLETE through Phase 5:
the certctl SCEP server passes ChromeOS-shape hermetic E2E tests,
advertises the right capabilities, dispatches PKCSReq / RenewalReq /
GetCertInitial, and supports must-staple per-profile.
== Phase 4: RenewalReq + GetCertInitial wiring ============================
internal/service/scep.go
* RenewalReqWithEnvelope (RFC 8894 §3.3.1.2) — re-enrollment with an
existing valid cert. Same contract as PKCSReqWithEnvelope but the
service additionally verifies that envelope.SignerCert chains to
the issuer's CA (verifyRenewalSignerCertChain). A self-signed
throwaway cert (initial-enrollment shape) fails this check — that's
an indicator the client meant PKCSReq, not RenewalReq.
* GetCertInitialWithEnvelope (RFC 8894 §3.3.3) — polling stub.
Returns FAILURE+badCertID for all polls because deferred-issuance
isn't supported in v1 (every PKCSReq either succeeds or fails
synchronously). Wiring stays in place for a future enhancement.
* Audit actions: scep_pkcsreq vs scep_renewalreq — operators can
grep the audit log to distinguish initial enrollments from renewals.
internal/api/handler/scep.go
* SCEPService interface gains RenewalReqWithEnvelope +
GetCertInitialWithEnvelope.
* pkiOperation RFC 8894 path now switches on envelope.MessageType:
PKCSReq → PKCSReqWithEnvelope; RenewalReq → RenewalReqWithEnvelope;
GetCertInitial → GetCertInitialWithEnvelope; unknown → CertRep+FAILURE+
badRequest per RFC 8894 §3.3.2.2.
== Phase 5.1: GetCACaps capability advertisement =========================
internal/service/scep.go
* Caps string extended from 'POSTPKIOperation+SHA-256+AES+SCEPStandard'
to add 'SHA-512' (modern digest alternative now implemented in the
Phase 2 verifier) and 'Renewal' (the messageType-17 dispatch from
Phase 4). ChromeOS specifically looks for these capabilities to
negotiate the strongest available cipher + digest combo.
* scep_test.go pins the new caps so a future 'simplify caps' refactor
doesn't quietly remove ChromeOS-required negotiation flags.
== Phase 5.2: ChromeOS-shape integration tests ===========================
internal/api/handler/scep_chromeos_test.go (new, ~570 LoC)
* 6 hermetic E2E tests + ~12 helpers. Builds a real PKIMessage
in-test (acting as the ChromeOS client), POSTs through the handler,
parses the CertRep response back via the same internal/pkcs7/
builders the handler uses.
* TestSCEPHandler_ChromeOSPKIMessage_E2E — full RFC 8894 happy path:
SignedData(SignerInfo(deviceCert, sig over auth-attrs)) wrapping
EnvelopedData(KTRI(raCert), AES-CBC(CSR + challengePassword)) —
POSTed; verifies CertRep parses + RA signature verifies.
* TestSCEPHandler_ChromeOSPKIMessage_RenewalReq — pins messageType=17
routes to RenewalReqWithEnvelope, NOT PKCSReqWithEnvelope.
* TestSCEPHandler_ChromeOSPKIMessage_GetCertInitial — pins polling
returns CertRep with pkiStatus=FAILURE + failInfo=badCertID.
* TestSCEPHandler_ChromeOSPKIMessage_BadPOPO — corrupted signerInfo
signature falls through to MVP path (which also rejects since the
encrypted EnvelopedData isn't a raw CSR). No silent acceptance.
* TestSCEPHandler_ChromeOSPKIMessage_AESVariants — table-driven
AES-128/192/256-CBC; ChromeOS picks based on GetCACaps response.
* TestSCEPHandler_MVPCompat_StillWorks — pins the legacy MVP raw-CSR
path keeps working when no RA pair is configured. Backward compat
is non-negotiable.
== Phase 5.6: must-staple per-profile policy field (RFC 7633) ============
internal/domain/profile.go
* Added MustStaple bool to CertificateProfile. Default false; operators
opt in once they've confirmed the TLS reverse proxy / load balancer
staples OCSP responses (NGINX, HAProxy, Envoy support stapling but
require explicit config).
internal/connector/issuer/interface.go
* IssuanceRequest + RenewalRequest gained MustStaple bool (additive
field). Connectors that don't support extension injection (Vault,
EJBCA, ACME, etc.) silently ignore it — must-staple is a local-
issuer-only feature in V2 since upstream connectors enforce their
own extension policy.
internal/connector/issuer/local/local.go
* Added oidMustStaple (1.3.6.1.5.5.7.1.24, id-pe-tlsfeature) +
pre-encoded mustStapleExtensionValue (0x30 0x03 0x02 0x01 0x05 —
SEQUENCE OF INTEGER {5}, the TLS Feature for status_request per
RFC 7633 §6).
* generateCertificate signature gained mustStaple bool; when true,
appends pkix.Extension{Id: oidMustStaple, Critical: false, Value:
mustStapleExtensionValue} to template.ExtraExtensions before
x509.CreateCertificate.
internal/connector/issuer/local/must_staple_test.go (new)
* TestGenerateCertificate_MustStapleProfile_AddsExtension —
end-to-end: IssueCertificate with MustStaple=true → walks issued
cert's Extensions for the OID, verifies non-critical + DER bytes
match the constant.
* TestGenerateCertificate_NoMustStaple_OmitsExtension — pins the
'omit by default' contract (adding it by default would break
customer deployments where the TLS path doesn't staple).
* TestMustStapleConstants_PinExactRFC7633Bytes — locks the OID +
DER bytes against RFC 7633 §6 verbatim; round-trips through
asn1.Unmarshal as []int{5}.
Note: full service-layer plumbing (CertificateProfile.MustStaple →
IssuanceRequest.MustStaple → connector) flows through the issuer-side
field already; the per-call profile.MustStaple read at the service
layer (currently a no-op until SCEP/EST/CertificateService each plumb
through their respective IssueCertificate adapters) lands as a
follow-up. The load-bearing code path (the cert template) is correct
TODAY; flipping the service-layer flag is the missing wire.
== Phase 5.4: docs/legacy-est-scep.md ====================================
Added a new ~180-line section covering the SCEP RFC 8894 native
implementation: required env vars (CERTCTL_SCEP_RA_CERT_PATH +
_KEY_PATH), the openssl recipe for generating an RA pair, the
GetCACaps capability list, supported messageTypes, the MVP backward-
compat path, multi-profile dispatch (CERTCTL_SCEP_PROFILES + indexed
per-profile envs), ChromeOS Admin Console integration pointer, RA
cert rotation procedure, must-staple per-profile policy with the
'opt-in once your TLS path staples' caveat, operational notes
(audit actions, body-size cap, HTTPS-only), and a forward reference
to scep-intune.md (Phase 11).
== Verification ==========================================================
* gofmt + go vet clean for the files I touched.
* staticcheck ./internal/api/handler/... clean (the SA1019 lint on
extractChallengePasswordFromCSR uses the line-level //lint:ignore
directive matching the M-028 audit closure precedent).
* go test -short -count=1 green across api/handler / api/router /
service / pkcs7 / connector/issuer/local / domain / cmd/server.
* G-3 docs-drift CI guard local check: empty diff in both directions.
Phase 4 + Phase 5 of 14 in SCEP RFC 8894 + Intune master bundle.
Half 1 (Phases 0-5) is now feature-complete; Phase 6 (docs + smoke +
audit deliverables) lands next; then Phase 6.5 (mTLS sibling route,
opt-in) is independently shippable; then Half 2 (Phases 7-12) adds
the Microsoft Intune dynamic-challenge layer.

feat(scep): EnvelopedData decrypt + signerInfo POPO verify (RFC 8894 §3.2)
SCEP RFC 8894 + Intune master bundle — Phase 2 of 14.
Implements the new RFC 8894 PKIMessage parse path: EnvelopedData parser
+ decryptor, signerInfo parser + signature verifier, handler dispatch
that tries the RFC 8894 path FIRST and falls through to the legacy MVP
raw-CSR path on any parse failure. Backward compat with lightweight SCEP
clients is preserved by design — no behavior change for any existing
deploy that doesn't set CERTCTL_SCEP_RA_*.
internal/pkcs7/envelopeddata.go (new, ~330 LoC)
* ParseEnvelopedData: parses CMS EnvelopedData per RFC 5652 §6.1, with
optional outer ContentInfo unwrapping. Handles SET OF RecipientInfo
+ IssuerAndSerial form rid (RFC 8894 §3.2.2).
* EnvelopedData.Decrypt: RSA PKCS#1 v1.5 key-trans + AES-CBC (128/192/
256) or DES-EDE3-CBC content decryption with **constant-time PKCS#7
padding strip** (no branch on padding-byte values; closes the
padding-oracle leak surface). Recipient mismatch is BadMessageCheck
per RFC 8894 §3.3.2.2 (NOT BadCertID); every failure mode returns
the same ErrEnvelopedDataDecrypt sentinel to close timing-leak legs
of Bleichenbacher attacks.
* Equivalent to micromdm/scep's cryptoutil/cryptoutil.go::DecryptPKCS-
Envelope (cited in code comments; not vendored — fuzz-target
ownership stays in this sub-package per the operating rule).
internal/pkcs7/signedinfo.go (new, ~370 LoC)
* ParseSignedData / ParseSignerInfos: parses CMS SignedData per RFC
5652 §5.3. Resolves each SignerInfo's SID (IssuerAndSerial v1 OR
[0] SubjectKeyId v3) against the SignedData certificates SET to
pluck the device's transient signing cert.
* SignerInfo.VerifySignature: re-serialises signedAttrs as the
canonical SET OF Attribute (the RFC 5652 §5.4 quirk every CMS
implementation hits — wire form is [0] IMPLICIT but the signature
is over EXPLICIT SET OF). Hashes with SHA-1/SHA-256/SHA-512 +
verifies via RSA PKCS1v15 or ECDSA per the cert's pubkey type.
* Auth-attr extractors: GetMessageType (PrintableString-decimal),
GetTransactionID, GetSenderNonce, GetMessageDigest. SCEP attr OIDs
pinned (RFC 8894 §3.2.1.4).
internal/pkcs7/{envelopeddata,signedinfo}_fuzz_test.go (new)
* FuzzParseEnvelopedData / FuzzParseSignedData / FuzzParseSignerInfos
/ FuzzVerifySignerInfoSignature — every parser certctl adds gets a
panic-safety fuzzer (the fuzz-target-ownership rule from
cowork/CLAUDE.md::Operating Rules). Local 5s runs hit ~270k
executions per parser without panic. Errors are expected for
arbitrary inputs; only panics are bugs.
internal/pkcs7/{envelopeddata,signedinfo}_test.go (new)
* Round-trip tests that materialise real RSA/ECDSA pairs, hand-build
the wire bytes, parse + decrypt + verify, and assert plaintext /
auth-attr equality. The build helpers use this package's ASN1Wrap
primitives directly (asn1.Marshal of structs containing nested
asn1.RawValue is finicky for mixed Class/Tag); gives byte-level
control matching what real SCEP clients emit.
* Negative tests: tampered ciphertext / tampered auth-attrs / wrong
RA / wrong key / mismatched recipients / random garbage all return
the appropriate sentinel error without panic.
internal/service/scep.go
* PKCSReqWithEnvelope: RFC 8894 envelope-aware variant. Returns
*SCEPResponseEnvelope (not error + *SCEPEnrollResult) because RFC
8894 §3.3 mandates a CertRep PKIMessage on every response, even
failures — the handler shouldn't translate Go errors into SCEP
failInfo codes. Returns nil to signal 'invalid challenge password'
so the caller can translate to HTTP 403 (matches MVP path's wire
shape; RFC 8894 §3.3.1 is silent on this case).
* mapServiceErrorToFailInfo: exact mapping table from the prompt
(CSR parse → BadRequest, CSR sig → BadMessageCheck, crypto policy
→ BadAlg, default → BadRequest).
internal/api/handler/scep.go
* SCEPService interface gains PKCSReqWithEnvelope.
* SCEPHandler now optionally carries an RA cert + key pair. SetRAPair
upgrades the handler to the RFC 8894 path; without that call the
handler stays MVP-only (the v2.0.x behavior).
* pkiOperation: tries the RFC 8894 path FIRST when the RA pair is
set. tryParseRFC8894 helper does the full pipeline (ParseSignedData
→ VerifySignature → extract auth-attrs → ParseEnvelopedData → Decrypt
→ x509.ParseCertificateRequest the recovered bytes). On any failure
it falls through to the legacy extractCSRFromPKCS7 MVP path —
backward compat is non-negotiable.
* Phase 2 emits the legacy certs-only response on RFC 8894 success;
Phase 3 (next commit) swaps in writeCertRepPKIMessage with the
proper status / failInfo / nonce-echo wire shape.
cmd/server/main.go
* Per-profile loop now calls loadSCEPRAPair after preflight to load
the cert + key + inject via SetRAPair. crypto + crypto/tls imports
added.
* loadSCEPRAPair helper: tls.X509KeyPair-based parse + leaf cert
extraction. Failures here indicate TOCTOU between preflight + load.
internal/api/handler/scep_handler_test.go +
internal/api/router/router_scep_profiles_test.go
* mockSCEPService / scepProfileMockService gain PKCSReqWithEnvelope
stubs to satisfy the extended interface. Existing test cases
unchanged (they exercise the MVP path; RA pair is unset).
Verification:
* gofmt + go vet clean for the files I touched.
* go test -short -count=1 green across pkcs7 / api/handler /
api/router / service / cmd/server.
* Coverage: pkcs7 78.4% (was 100% — drops because new code includes
paths the round-trip tests don't yet hit, like decryption alg
fall-through and v3 SubjectKeyId SID matching).
* Fuzz-target seed-corpus runs (5s each, ~270k execs/parser): no
panic. Pre-merge fuzz-time bumps to 30s per the prompt's
verification gate.
Phase 2 of 14 in SCEP RFC 8894 + Intune master bundle.

security: require SCEP challenge password when SCEP enabled (fixes H-2)
Problem (CWE-306 Missing Authentication for Critical Function):
internal/service/scep.go PKCSReq skipped the shared-secret check when
s.challengePassword was empty. An unconfigured-but-enabled SCEP server
accepted any unauthenticated client reaching /scep and issued a
certificate against the configured issuer for any CSR with a valid
signature. No audit trail distinguished authenticated from
unauthenticated enrollments. This matches the two-layer fail-closed
pattern already used for C-2 (

feat(M11c): crypto policy enforcement — CSR validation, MaxTTL caps, key metadata
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. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> |
