Functionality Verification ✅ ### 5.1 DNSProviderCredential Model ✅ **Location:** `backend/internal/models/dns_provider_credential.go` **Verification:** - ✅ All required fields present - ✅ Proper GORM tags (indexes, foreign keys) - ✅ `json:"-"` tag on `CredentialsEncrypted` (prevents exposure) - ✅ UUID field with unique index - ✅ Key version support for rotation - ✅ Usage tracking fields (last_used_at, success/failure counts) - ✅ Propagation settings with defaults - ✅ Enabled flag for soft disable ### 5.2 Zone Matching Algorithm ✅ **Location:** `backend/internal/services/credential_service.go` (lines 456-560) **Algorithm Priority:** 1. ✅ **Exact Match** - `example.com` matches `example.com` 2. ✅ **Wildcard Match** - `*.example.com` matches `sub.example.com` 3. ✅ **Catch-All** - Empty zone_filter matches any domain **Test Coverage:** ``` ✅ Exact match: example.com → example.com ✅ Wildcard match: *.example.org → sub.example.org ✅ Catch-all: "" → any.domain.com ✅ Multiple zones: "example.com,other.com" → both domains ✅ IDN support: 测试.example.com (converted to punycode) ✅ Case insensitive: Example.COM → example.com ✅ No match: returns ErrNoMatchingCredential ``` **Verdict:** ✅ **FULLY FUNCTIONAL** ### 5.3 Caddy Integration ✅ **Location:** `backend/internal/caddy/manager_helpers.go` **Verification:** - ✅ `getCredentialForDomain()` uses `GetCredentialForDomain` service - ✅ Falls back to provider credentials if multi-cred not enabled - ✅ Proper decryption with key version support - ✅ Zone-specific credential selection in config generation - ✅ Error handling for missing credentials **Integration Points:** ``` ✅ manager.go:208 - Calls getCredentialForDomain per domain ✅ manager_helpers.go:68-120 - Credential resolution logic ✅ manager_multicred_test.go - 3 comprehensive tests ``` ### 5.4 Frontend Credential Management ✅ **Components:** - ✅ `CredentialManager.tsx` - Full CRUD modal for credentials - ✅ `useCredentials.ts` - React Query hooks - ✅ `credentials.ts` - API client with all endpoints - ✅ `DNSProviderSelector.tsx` - Multi-credential toggle **Features Verified:** - ✅ Create credential with zone filter - ✅ Edit credential - ✅ Delete credential with confirmation - ✅ Test credential connection - ✅ Enable multi-credential mode - ✅ Zone filter input (comma-separated, wildcards) - ✅ Credential form validation - ✅ Error handling and toast notifications ### 5.5 Multi-Credential Toggle ✅ **Verification:** - ✅ Toggle switch in DNS provider form - ✅ Calls `enableMultiCredentials` API - ✅ Migrates single credential to multi-credential mode - ✅ Creates default catch-all credential from existing - ✅ Sets `use_multi_credentials` flag - ✅ Irreversible (as designed for safety) --- ## 6. Regression Testing ✅ ### 6.1 Single Credential Mode (Backward Compatibility) ✅ **Test:** Provider with `UseMultiCredentials=false` **Verification:** ``` ✅ Existing providers work without multi-credential ✅ Caddy uses provider.CredentialsEncrypted directly ✅ GetCredentialForDomain returns nil (uses main cred) ✅ List credentials returns ErrMultiCredentialNotEnabled ✅ No breaking changes to existing APIs ``` ### 6.2 Phase 1 (Audit Logging) ✅ **Test:** Audit events for credential operations **Verification:** ``` ✅ credential_create logged ✅ credential_update logged ✅ credential_delete logged ✅ credential_test logged ✅ All events include resource_id, details, actor ``` ### 6.3 Phase 2 (Key Rotation) ✅ **Test:** Credential encryption with key versioning **Verification:** ``` ✅ KeyVersion field stored in DNSProviderCredential ✅ RotationService.DecryptWithVersion() used ✅ Falls back to basic encryptor if rotation unavailable ✅ Encrypted credentials never exposed (json:"-" tag) ``` ### 6.4 Existing Tests ✅ **Verification:** - ✅ All pre-Phase 3 tests still pass - ✅ No breaking changes to existing endpoints - ✅ DNS provider CRUD unchanged - ✅ Certificate generation unaffected --- ## 7. Security Verification ✅ ### 7.1 Encryption at Rest ✅ **Verification:** - ✅ **Algorithm:** AES-256-GCM - ✅ **Key Versioning:** Supported via `key_version` field - ✅ **Storage:** `credentials_encrypted` field (text blob) - ✅ **Key Source:** Environment variable (CHARON_ENCRYPTION_KEY) **Code References:** ```go // credential_service.go:150-160 encryptedData, err := s.rotationService.EncryptWithLatestKey(credJSON) credential.KeyVersion = s.rotationService.GetLatestKeyVersion() ``` ### 7.2 Credential Exposure Prevention ✅ **Verification:** - ✅ `json:"-"` tag on `CredentialsEncrypted` field - ✅ API responses never include raw credentials - ✅ Decryption only happens server-side - ✅ Frontend receives only metadata (label, zone_filter, enabled) **Test:** ```go // API response excludes credentials_encrypted type DNSProviderCredential struct { CredentialsEncrypted string `json:"-"` // NEVER sent to client } ``` ### 7.3 Audit Logging ✅ **Verification:** - ✅ All credential operations logged - ✅ Actor, action, resource tracked - ✅ Details include label, zone_filter, provider_id - ✅ Test results logged (success/failure) **Logged Events:** ``` credential_create credential_update credential_delete credential_test ``` ### 7.4 Zone Isolation ✅ **Verification:** - ✅ Zone matching algorithm prevents credential leakage - ✅ Each domain uses only its matching credential - ✅ No cross-zone credential access - ✅ Priority system ensures correct selection **Test Scenarios:** ``` Domain: example.com → Credential A (zone: example.com) Domain: other.com → Credential B (zone: other.com) Domain: sub.example.com → Credential C (zone: *.example.com) ``` ### 7.5 Access Control ✅ **Verification:** - ✅ Credential endpoints require authentication - ✅ Provider ownership verified before credential access - ✅ Admin-only access where appropriate - ✅ RBAC integration (via AuthMiddleware) --- ## 8. Backward Compatibility ✅ ### 8.1 Single Credential Mode ✅ **Verification:** - ✅ Providers with `UseMultiCredentials=false` work normally - ✅ No code changes required for existing providers - ✅ Caddy config generation backward compatible - ✅ API endpoints return proper errors when multi-cred not enabled ### 8.2 Migration Path ✅ **Verification:** - ✅ `EnableMultiCredentials()` creates default catch-all credential - ✅ Migrates existing `credentials_encrypted` to new credential - ✅ Sets `use_multi_credentials=true` flag - ✅ Preserves all existing provider settings - ✅ Irreversible (safety measure to prevent data loss) **Code:** ```go // credential_service.go:552-620 func (s *credentialService) EnableMultiCredentials(ctx context.Context, providerID uint) error { // Creates default credential with empty zone_filter (catch-all) // Copies existing credentials_encrypted // Updates provider.UseMultiCredentials = true } ``` ### 8.3 API Compatibility ✅ **Verification:** - ✅ No breaking changes to existing endpoints - ✅ New credential endpoints prefixed: `/api/dns-providers/:id/credentials` - ✅ Optional multi-credential toggle in provider update - ✅ Existing client code unaffected --- ## 9.
