The accumulated step breadcrumb is appended to EnrollmentResult.StatusMessage on both success and failure, so operators see a scannable per-step summary in the Command UI instead of just a single exception message. Changes: - FlowLogger.cs: ported verbatim from barracuda with namespace changed to Keyfactor.Extensions.CAPlugin.Acme. Added StepAsync overload for async methods that return a value. - Enroll: wraps each stage (ValidateInput, FormatCsr, LoadConfig, CreateHttpClient, InitAcmeAccount, CreateAcmeClient, DecodeCsr, ExtractDomainsFromCsr, CreateOrder, ExtractOrderIdentifier, FinalizeOrder, DownloadCertificate, EncodeCertificateToPem) as a timed flow.Step. Success returns include flow.GetSummary(); failure paths include DescribeException(ex) + flow.GetSummary(). - ProcessAuthorizations: takes the flow and records per-domain work in three branches (StageDnsRecords / VerifyAndSubmit / CleanupDnsRecords), so the breadcrumb shows which specific domain failed when a challenge breaks. - DescribeException helper: unwraps AggregateException/TargetInvocation wrappers, surfaces HttpRequestException context, and truncates overlong messages so the summary stays readable. - Initialize: added ValidateConfigForEnrollment — fails fast (at save time, not first enroll) on missing DirectoryUrl/Email, non-absolute or non-http(s) DirectoryUrl, mismatched EAB key pair, or negative DnsPropagationDelaySeconds. Build: net6.0 / net8.0 / net10.0 — 0 errors, pre-existing warnings only.

DNS Provider Plugin Architecture

+

Developer guide — how a CA Gateway plugin and DNS provider plugins interact end-to-end

+
+ +

+ This document walks through the code-level integration between a Keyfactor CA Gateway plugin + (e.g. the ACME CA plugin) and the DNS provider plugins that it delegates domain-control validation to. + The AWS Route 53 DNS provider is used as the concrete example, but every provider plugin + (Azure DNS, Cloudflare, NS1, RFC 2136, Infoblox, Google Cloud DNS) follows the same contract. +

+ +

1. Architectural Overview

+ +

+ The CA Gateway plugin never talks to a DNS provider’s SDK directly. Instead, it depends on a small + set of interfaces from Keyfactor.AnyGateway.IAnyCAPlugin + that let the gateway runtime resolve the correct provider at runtime — per-domain — based on + whatever provider DLLs have been dropped into the gateway’s extension folder. +

+ +
+ CA Plugin Gateway Runtime DNS Provider Plugin + + ┌─────────────────────┐ ┌─────────────────────┐ ┌──────────────────────────┐ + │ AcmeCaPlugin │ │ IDomainValidator- │ │ AwsRoute53Domain- │ + │ (IAnyCAPlugin) │─────▶│ Factory │────▶│ Validator │ + │ │ (1) │ (injected DI-style) │ (2) │ (IDomainValidator) │ + │ • Enroll │ │ │ │ • Initialize │ + │ • ProcessAuths │◀─────│ │◀────│ • StageValidation │ + └─────────────────────┘ (4) └─────────────────────┘ (3) │ • CleanupValidation │ + │ • GetValidationType │ + │ • GetDomainValidator- │ + │ Annotations │ + └───────────┬──────────────┘ + │ + ▼ + ┌──────────────────────────┐ + │ AwsRoute53DnsProvider │ + │ (wraps AWSSDK.Route53) │ + └───────────┬──────────────┘ + │ + ▼ + ┌──────────────────────────┐ + │ AWS Route 53 │ + │ (TXT record) │ + └──────────────────────────┘ +
+ +
    +
  1. Resolve — the CA plugin calls factory.ResolveDomainValidator(domain, challengeType).
    2. +
  2. Dispatch — the gateway returns the IDomainValidator implementation matching the domain’s zone.
    3. +
  3. Work — the CA plugin calls StageValidation() / CleanupValidation() on the validator.
    4. +
  4. Return — the validator returns a DomainValidationResult { Success, ErrorMessage }.
    5. +
+ +

2. The Contract

+ +

+ Three interfaces — all shipped in the Keyfactor.AnyGateway.IAnyCAPlugin + NuGet package — define the entire relationship: +

+ + + + + + +
InterfaceImplemented byPurpose
IDomainValidatorFactoryGateway runtimeResolves a validator given a domain + challenge type.
IDomainValidatorEach DNS provider pluginStages / cleans up the DNS record for a challenge.
IDomainValidatorConfigProviderGateway runtimeDelivers user-entered config to the validator at Initialize() time.
+ +

DomainValidationResult

+ +

The return shape is intentionally small:

+ +
public class DomainValidationResult
+{
+    public bool Success { get; set; }
+    public string ErrorMessage { get; set; }
+}
+ +

3. The CA Plugin Side (Caller)

+ +

+ The CA plugin receives an IDomainValidatorFactory through constructor injection, then + resolves a validator per-domain during enrollment. +

+ +

3.1 — Constructor injection

+ +AcmeCaPlugin/AcmeCaPlugin.cs +
public class AcmeCaPlugin : IAnyCAPlugin
+{
+    private readonly IDomainValidatorFactory _validatorFactory;
+
+    public AcmeCaPlugin(IDomainValidatorFactory validatorFactory)
+    {
+        _validatorFactory = validatorFactory ?? throw new ArgumentNullException(nameof(validatorFactory),
+            "IDomainValidatorFactory is required. DNS providers are externalized as plugins.");
+    }
+}
+ +

3.2 — Resolving the validator per-domain

+ +AcmeCaPlugin/AcmeCaPlugin.cs — inside ProcessAuthorizations() +
var domain = authz.Identifier.Value;
+
+var domainValidator = _validatorFactory.ResolveDomainValidator(domain, DNS_CHALLENGE_TYPE);
+if (domainValidator == null)
+{
+    throw new InvalidOperationException(
+        $"Failed to resolve domain validator for domain '{domain}'. " +
+        "Ensure the appropriate DNS provider plugin is deployed and configured.");
+}
+
+// Stage the DNS TXT record through whichever provider the gateway selected
+var result = await domainValidator.StageValidation(
+    validation.DnsRecordName,       // e.g. "_acme-challenge.example.com"
+    validation.DnsRecordValue,      // the ACME-provided challenge token
+    CancellationToken.None);
+
+if (!result.Success)
+    throw new InvalidOperationException(
+        $"Failed to stage DNS validation for {domain}: {result.ErrorMessage}");
+ +
+

Key insight: the CA plugin resolves a validator per domain, not per enrollment. + That is what allows a single cert request spanning api.example.com (Route 53) and + internal.corp (Infoblox) to work with zero special-casing in the CA plugin.

+
+ +

3.3 — Cleanup

+ +

+ Regardless of whether the challenge succeeded, the CA plugin calls CleanupValidation + on each validator it used, so temporary TXT records don’t linger in the customer’s zone. +

+ +
foreach (var (authz, challenge, validation, validator) in pendingChallenges)
+{
+    try
+    {
+        await validator.CleanupValidation(validation.DnsRecordName, CancellationToken.None);
+    }
+    catch (Exception ex)
+    {
+        _logger.LogWarning(ex, "Failed to cleanup DNS record for {Domain}", domain);
+        // Continue cleanup for other domains even if one fails
+    }
+}
+ +

4. The DNS Provider Plugin Side (AWS Route 53 Example)

+ +

+ A DNS provider plugin is a standalone .NET project that produces a single DLL plus a + manifest.json. No code in the CA plugin needs to change to add a new provider. +

+ +

4.1 — Project layout

+ +
aws-route53-dnsplugin/
+├── Keyfactor.DnsProvider.AwsRoute53/
+│   ├── AwsRoute53DomainValidator.cs      // implements IDomainValidator
+│   ├── AwsRoute53DnsProvider.cs          // wraps AWSSDK.Route53
+│   └── Keyfactor.DnsProvider.AwsRoute53.csproj
+├── manifest.json
+└── integration-manifest.json
+ +

4.2 — The validator class

+ +Keyfactor.DnsProvider.AwsRoute53/AwsRoute53DomainValidator.cs +
using Keyfactor.AnyGateway.Extensions;
+
+namespace Keyfactor.Extensions.DomainValidator.AwsRoute53
+{
+    public class AwsRoute53DomainValidator : IDomainValidator
+    {
+        private AwsRoute53DnsProvider _provider;
+        private Dictionary<string, object> _configuration;
+
+        public void Initialize(IDomainValidatorConfigProvider configProvider)
+        {
+            _configuration = configProvider.DomainValidationConfiguration;
+
+            string accessKey = GetConfigValue("AwsRoute53_AccessKey");
+            string secretKey = GetConfigValue("AwsRoute53_SecretKey");
+
+            _provider = new AwsRoute53DnsProvider(accessKey, secretKey);
+        }
+
+        public async Task<DomainValidationResult> StageValidation(
+            string key, string value, CancellationToken cancellationToken)
+        {
+            try
+            {
+                var success = await _provider.CreateRecordAsync(key, value);
+                return new DomainValidationResult
+                {
+                    Success = success,
+                    ErrorMessage = success ? null : $"Failed to create TXT record for {key}"
+                };
+            }
+            catch (Exception ex)
+            {
+                return new DomainValidationResult
+                {
+                    Success = false,
+                    ErrorMessage = $"Failed to create TXT record: {ex.Message}"
+                };
+            }
+        }
+
+        public async Task<DomainValidationResult> CleanupValidation(
+            string key, CancellationToken cancellationToken)
+        {
+            var success = await _provider.DeleteRecordAsync(key);
+            return new DomainValidationResult
+            {
+                Success = success,
+                ErrorMessage = success ? null : $"Failed to delete TXT record for {key}"
+            };
+        }
+    }
+}
+ +

4.3 — The actual AWS SDK call (the only provider-specific bit)

+ +Keyfactor.DnsProvider.AwsRoute53/AwsRoute53DnsProvider.cs +
var request = new ChangeResourceRecordSetsRequest
+{
+    HostedZoneId = zone.Id,
+    ChangeBatch = new ChangeBatch
+    {
+        Changes = new List<Change>
+        {
+            new Change
+            {
+                Action = ChangeAction.UPSERT,
+                ResourceRecordSet = new ResourceRecordSet
+                {
+                    Name = EnsureTrailingDot(recordName),
+                    Type = RRType.TXT,
+                    TTL = 60,
+                    ResourceRecords = new List<ResourceRecord>
+                    {
+                        new ResourceRecord { Value = $"\"{txtValue}\"" }
+                    }
+                }
+            }
+        }
+    }
+};
+
+var response = await _route53Client.ChangeResourceRecordSetsAsync(request);
+ +

4.4 — Declaring configurable properties

+ +

+ Each plugin declares its configuration surface so the gateway can render the fields in the Command UI: +

+ +
public Dictionary<string, PropertyConfigInfo> GetDomainValidatorAnnotations()
+{
+    return new Dictionary<string, PropertyConfigInfo>
+    {
+        ["AwsRoute53_AccessKey"] = new PropertyConfigInfo
+        {
+            Comments = "AWS Route53: Access Key ID (Optional if using IAM role)",
+            Hidden = false,
+            DefaultValue = "",
+            Type = "Secret"
+        },
+        ["AwsRoute53_SecretKey"] = new PropertyConfigInfo
+        {
+            Comments = "AWS Route53: Secret Access Key (Optional if using IAM role)",
+            Hidden = true,
+            DefaultValue = "",
+            Type = "Secret"
+        }
+    };
+}
+ +

5. Discovery: manifest.json

+ +

+ The gateway discovers plugins by scanning its extension folder for manifest.json files. + Each manifest names the plugin’s assembly, its implementation type, and its provider key — + everything the gateway needs to load the DLL by reflection and register it with the factory. +

+ +manifest.json +
{
+  "pluginType":       "DomainValidator",
+  "validationType":   "DNS",
+  "providerName":     "awsroute53",
+  "displayName":      "AWS Route53 DNS",
+  "description":      "DNS-01 challenge validation using AWS Route53",
+  "assemblyName":     "AwsRoute53DomainValidator.dll",
+  "typeName":         "Keyfactor.Extensions.DomainValidator.AwsRoute53.AwsRoute53DomainValidator",
+  "version":          "1.0.0",
+  "author":           "Keyfactor",
+  "configurationFields": [
+    "AwsRoute53_AccessKey",
+    "AwsRoute53_SecretKey"
+  ]
+}
+ +

csproj wiring so the manifest ships with the DLL

+ +
<ItemGroup>
+  <PackageReference Include="Keyfactor.AnyGateway.IAnyCAPlugin" Version="3.3.0-PRERELEASE-..." />
+  <PackageReference Include="AWSSDK.Core"    Version="4.0.3.11" />

6. End-to-End Sequence

+ +

A full happy-path enrollment that spans a Route 53 domain and an Infoblox domain:

+ +

7. Why This Shape

+ +
    +
  • CA-agnostic: any CA Gateway plugin (ACME, DigiCert, etc.) that needs DNS validation + uses the exact same three interfaces. Replacing the ACME plugin with a DigiCert plugin does not require + rebuilding any DNS provider.
    • +
  • Minimum surface area per provider: a DNS plugin only has to deal with + one thing — creating and deleting a TXT record. No awareness of the ACME protocol, + no awareness of the CA plugin, no awareness of the gateway’s lifecycle.
    • +
  • Independent deployment: a bugfix in the Route 53 plugin ships as a single DLL. + Customers upgrade only the providers they actually use.
    • +
  • Credentials stay isolated: AWS keys live in the Route 53 plugin’s config + scope; they are never visible to the CA plugin or to other DNS provider plugins.
    • +
+ +

8. Building a New DNS Provider — Checklist

+ +
    +
  1. New .NET class library project targeting the same TFM as the gateway.
    2. +
  2. Reference Keyfactor.AnyGateway.IAnyCAPlugin.
    3. +
  3. Implement IDomainValidator — Initialize, StageValidation, + CleanupValidation, GetValidationType, GetDomainValidatorAnnotations, + ValidateConfiguration.
    4. +
  4. Add a manifest.json with pluginType: "DomainValidator", + a unique providerName, the assemblyName, and the fully-qualified + typeName.
    5. +
  5. Mark manifest.json as CopyToOutputDirectory: Always in the csproj.
    6. +
  6. Build — drop the output DLL + manifest into the gateway’s extension folder — restart the gateway.
    7. +
  7. Configure the plugin’s fields in the Command UI — the annotations you returned from + GetDomainValidatorAnnotations become the form schema.
    8. +
+ +
+

Tip: use an existing plugin (e.g. AWS Route 53) as a template. Every provider + plugin in the Keyfactor ecosystem has the same skeleton — the only meaningful difference is + how StageValidation/CleanupValidation talk to the vendor’s API.

This also means a single certificate with SANs across different zones/providers can be validated using different plugins, and CNAME-delegated challenges are routed to the plugin that owns the delegation target's zone (see **CNAME Delegation** above).

From 389a2c493f5a9ae0256d6276aca36b6ada18f849 Mon Sep 17 00:00:00 2001 From: Brian Hill Date: Wed, 8 Jul 2026 10:52:32 -0400 Subject: [PATCH 34/37] Remove externalized DNS provider config and unused SDK dependencies DNS providers are now separate plugins, so the ACME plugin no longer needs their SDKs or per-provider config fields. Drop the AWS, Azure, ARSoft (RFC2136), and Nager.PublicSuffix package references (all unused in code) and remove the DnsProvider selector plus every per-provider config entry from the integration manifest. Keep the ACME-level fields, AccountStoragePath (still used for account storage), and DnsVerificationServer (used for propagation checks and CNAME resolution). DnsClient is retained for CNAME delegation and TXT propagation. --- AcmeCaPlugin/AcmeCaPlugin.csproj | 28 +---------- integration-manifest.json | 86 +------------------------------- 2 files changed, 3 insertions(+), 111 deletions(-) diff --git a/AcmeCaPlugin/AcmeCaPlugin.csproj b/AcmeCaPlugin/AcmeCaPlugin.csproj index 942c7ec..961da45 100644 --- a/AcmeCaPlugin/AcmeCaPlugin.csproj +++ b/AcmeCaPlugin/AcmeCaPlugin.csproj @@ -22,32 +22,8 @@ - - - - - - - - - - - - - - - - - - - - - - - - - - + diff --git a/integration-manifest.json b/integration-manifest.json index 08ba468..77a7475 100644 --- a/integration-manifest.json +++ b/integration-manifest.json @@ -37,97 +37,13 @@ "name": "SignerEncryptionPhrase", "description": "Used to encrypt singer information when account is saved to disk (optional)" }, - { - "name": "DnsProvider", - "description": "DNS Provider to use for ACME DNS-01 challenges (options: Google, Cloudflare, AwsRoute53, Azure, Ns1, Rfc2136, Infoblox)" - }, - { - "name": "Google_ServiceAccountKeyPath", - "description": "Google Cloud DNS: Path to service account JSON key file only if using Google DNS (Optional)" - }, - { - "name": "Google_ServiceAccountKeyJson", - "description": "Google Cloud DNS: Service account JSON key content (alternative to file path for containerized deployments)" - }, - { - "name": "Google_ProjectId", - "description": "Google Cloud DNS: Project ID only if using Google DNS (Optional)" - }, { "name": "AccountStoragePath", "description": "Path for ACME account storage.
