EncryptIfKeySet/DecryptIfKeySet in internal/crypto/encryption.go previously
returned plaintext + wasEncrypted=false when the operator had not configured
CERTCTL_CONFIG_ENCRYPTION_KEY. That produced a data-at-rest confidentiality
bypass (CWE-311): sensitive fields on dynamically-configured issuer and
target rows (source='database') were persisted to PostgreSQL without any
encryption, and no caller could distinguish the encrypted from the plaintext
branch at runtime. The only visible signal was a single warning log line
emitted once at startup.
Fail closed instead:
- EncryptIfKeySet / DecryptIfKeySet now return crypto.ErrEncryptionKeyRequired
(a new exported sentinel, errors.Is-unwrappable) when the key is empty or
nil, rather than silently emitting plaintext. The (result, wasEncrypted,
err) tuple signature is preserved for source compatibility; only the
semantics of the no-key branch changed.
- cmd/server/main.go grows a startup pre-flight check: if no encryption key
is configured the server lists issuers and targets, counts rows with
source='database', and refuses to start (os.Exit(1)) if any exist. Operators
must either configure CERTCTL_CONFIG_ENCRYPTION_KEY or remove the exposed
rows before the control plane can boot. The warning-only path is retained
for the clean-slate case (no database rows).
- internal/service/issuer.go's SeedFromEnvVars now guards the encryption call
with len(s.encryptionKey) > 0 so env-seeded rows (source='env', which are
reconstructable on every boot from process env) continue to persist as
plaintext in the 'config' column when no key is configured. Registry load
already falls through to cfg.Config when EncryptedConfig is nil. GUI/API
write paths (source='database') remain fail-closed via propagation of
ErrEncryptionKeyRequired.
- Integration tests that exercise CreateIssuer via the handler layer now
supply a real 32-byte AES-256 test key so the encrypt path runs instead of
returning ErrEncryptionKeyRequired. Same pattern in internal/service/
testutil_test.go for consolidated service-layer tests.
- internal/crypto/encryption_test.go grows regression guards:
TestEncryptIfKeySet_EmptyKeyFailsClosed (nil_key + empty_key subtests),
TestDecryptIfKeySet_EmptyKeyFailsClosed (nil_key + empty_key subtests),
TestEncryptDecryptIfKeySet_RoundTripProducesDifferentCiphertext,
TestDecryptIfKeySet_RejectsTamperedCiphertext, and
TestEncryptIfKeySet_PreservesErrEncryptionKeyRequiredSentinel (verifies
the sentinel unwraps through fmt.Errorf(%w)-style wrapping).
Wire format is unchanged: AES-256-GCM Encrypt/Decrypt/DeriveKey, the
12-byte nonce prefix, the GCM auth tag, the PBKDF2 salt
('certctl-config-encryption-v1'), and the 100,000 iteration count are all
byte-identical. Ciphertexts produced before this change remain decryptable.

Replaces math/rand-based agent API key generation in internal/service/agent.go
with crypto/rand.Read over a 32-byte buffer encoded with base64.RawURLEncoding,
yielding a 43-character URL-safe unpadded ASCII string (256 bits of entropy).
generateAPIKey now returns (string, error); Register and RegisterAgent propagate
entropy-source failures. hashAPIKey is unchanged — the SHA-256 hashed-at-rest
invariant is preserved.
Fixes C-1 (CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator)
from certctl-audit-report.md.
Changes:
- internal/service/agent.go: new imports (crypto/rand, encoding/base64);
generateAPIKey rewritten to return (string, error); Register and RegisterAgent
updated to propagate the error.
- internal/service/agent_test.go: TestGenerateAPIKey_Properties regression test
(non-empty, length 43, valid base64url, 32 decoded bytes, no collisions over
64 calls). No entropy-failure test — Go 1.24+ (issue #66821) makes crypto/rand
errors fatal, so that branch is defensively unreachable.

The previous fix (--include=dev) was necessary but insufficient. The
real issue is that node_modules created by npm ci in one layer can be
lost when COPY web/ . creates the next layer — depending on the Docker
storage driver (fuse-overlayfs, vfs). Merging install and build into a
single RUN eliminates the layer boundary entirely.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
npm ci skips devDependencies when NODE_ENV=production leaks from the
host environment into the Docker build. This breaks the frontend stage
because typescript and vite are devDependencies. Adding --include=dev
makes the install hermetic regardless of host environment.

Backend rejected lowercase type strings (e.g., "acme") sent by older
cached frontends. Add normalizeIssuerType() with alias map for
case-insensitive lookup, wire into both Create paths. Add missing
Entrust/GlobalSign/EJBCA to validIssuerTypes. Add lowercase fallbacks
to issuer factory switch. 39 new test subtests covering normalization,
lowercase create flows, and M49 type acceptance.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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,

CI thresholds, missing connectors in Mermaid diagrams, OpenAPI operation
count, GetCACertPEM behavior, and V2/V4 roadmap accuracy.
Also includes related fixes discovered during audit:
- Scheduler skips expired/failed/revoked certs from auto-renewal
- Seed demo expiry dates moved outside 31-day scheduler query window
- Agent pages use correct last_heartbeat_at field name

The Kubernetes Secrets target connector has config validation, tests, UI,
and Helm RBAC implemented but the realK8sClient is a stub — runtime
deployment will fail. Update README and connectors.md to reflect actual

Also increase the audit trail GUI default from 50 to 200 events per page
(backend already permits up to 500).

Closes#7. The issuer create/update handlers swallowed all service errors
as generic 500s. Now differentiates: 409 for UNIQUE constraint violations,
400 for unsupported issuer type, 404 for not-found on update, 500 for
unknown errors. Adds structured error logging via slog.
OnboardingWizard now pre-populates config field defaults when a type is
selected (matching IssuersPage behavior), preventing empty required fields
from causing silent failures.
install-agent.sh hardened for curl|bash usage: --agent-id flag, =value
syntax, /dev/tty stdin reopening, proper stderr routing in download_binary,
non-interactive install examples in help text, and updated wizard commands.
Adds adversarial security tests for EST, path traversal, and query
injection handlers.

Full audit of all ~100 backend API endpoints against frontend client functions
and TypeScript interfaces. Fixes field name mismatches, missing client functions,
phantom interface fields, type coercion for Go bool/int config fields, and
issuer type ID alignment with backend domain constants.
Backend:
- issuer.go/target.go: GUI-created entities default enabled=true (Go bool
zero value was overriding DB DEFAULT)
Frontend types (types.ts):
- Certificate: fingerprint→fingerprint_sha256, phantom fields made optional
- CertificateVersion: fingerprint→fingerprint_sha256, chain_pem→pem_chain,
removed phantom version/cert_pem fields
- Job: error_message→last_error (matches Go json tag)
Frontend client (client.ts):
- Added getNotification(id) and getAuditEvent(id) for existing backend routes
Frontend pages:
- CertificateDetailPage: derives serial/fingerprint/issuedAt from latest
CertificateVersion instead of empty Certificate fields
- JobsPage/JobDetailPage: error_message→last_error
- TargetsPage: reload_cmd→reload_command, validate_cmd→validate_command,
added missing config fields per backend structs (validate_command for
NGINX/Apache, hostname/winrm_timeout for IIS, private_key/passphrase/
cert_mode/key_mode for SSH, winrm_https/winrm_insecure for WinCertStore,
create_keystore for JavaKeystore, mode for Dovecot), type coercion via
buildConfigPayload() with BOOL_FIELDS/INT_FIELDS sets, IIS WinRM nesting
- TargetDetailPage: added passphrase to sensitiveKeys redaction
- issuerTypes.ts: type IDs aligned to backend constants (acme→ACME,
local→GenericCA, stepca→StepCA, openssl→OpenSSL), backward compat aliases
preserved, step-ca config fields updated to match backend struct
Utilities (utils.ts):
- formatDate/formatDateTime accept string|undefined|null

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.

Adds a new target connector enabling certificate deployment to any
Linux/Unix server without installing the certctl agent binary. Uses the
proxy agent pattern — a single agent in the same network zone deploys
certs to remote servers over SSH/SFTP.
Key additions:
- SSH/SFTP connector with key auth (file/inline) + password auth
- Injectable SSHClient interface for cross-platform testing (25 tests)
- Shell injection prevention via validation.ValidateShellCommand()
- Configurable cert/key/chain paths with octal permissions
- GUI: 11 SSH config fields in target create wizard
Also fixes pre-existing frontend bug where all target type strings
(nginx, apache, etc.) were sent as lowercase but the backend expects
proper-case (NGINX, Apache, etc.), breaking GUI-created targets.
Adds missing TargetTypeSSH to validTargetTypes service map.

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
