Introduction

This AnyGateway plug-in enables issuance, revocation, and synchronization of certificates from the Hashicorp Vault PKI Secrets Engine.

Hashicorp Vault Authentication

This plug-in supports two types of authentication into Hashicorp Vault.

1. Token
2. Certificate

When filling in the configuration values, if a value for "AuthToken" is present, it will be used. If not, then the values for certificate location should be populated for Authentication via certificate.

Prerequisites

Certificate Chain

In order to enroll for certificates the Keyfactor Command server must trust the trust chain. Once you create your Root and/or Subordinate CA, make sure to import the certificate chain into the AnyGateway and Command Server certificate store

Install

• Download latest successful build from GitHub Releases

• Copy .dll to the Program Files\Keyfactor\Keyfactor AnyGateway directory

• Update the CAProxyServer.config file

  • Update the CAConnection section to point at the DigiCertCAProxy class

  <alias alias="CAConnector" type="Keyfactor.Extensions.AnyGateway.Company.Product.GatewayNameCAConnector, DLLName"/>

Configuration

The following sections will breakdown the required configurations for the AnyGatewayConfig.json file that will be imported to configure the AnyGateway.

Templates

The Template section will map the CA's products to an AD template.

• ProductID This is the ID of the product to map to the specified template.

 "Templates": {
   "WebServer": {
     "ProductID": "<productID>",
     "Parameters": {
     }
  }
}

Security

The security section does not change specifically for the Hashicorp Vault PKI CA Gateway. Refer to the AnyGateway Documentation for more detail.

  /*Grant permissions on the CA to users or groups in the local domain.
	READ: Enumerate and read contents of certificates.
	ENROLL: Request certificates from the CA.
	OFFICER: Perform certificate functions such as issuance and revocation. This is equivalent to "Issue and Manage" permission on the Microsoft CA.
	ADMINISTRATOR: Configure/reconfigure the gateway.
	Valid permission settings are "Allow", "None", and "Deny".*/
    "Security": {
        "Keyfactor\\Administrator": {
            "READ": "Allow",
            "ENROLL": "Allow",
            "OFFICER": "Allow",
            "ADMINISTRATOR": "Allow"
        },
        "Keyfactor\\gateway_test": {
            "READ": "Allow",
            "ENROLL": "Allow",
            "OFFICER": "Allow",

        }
    }

CerificateManagers

The Certificate Managers section is optional. If configured, all users or groups granted OFFICER permissions under the Security section must be configured for at least one Template and one Requester. Uses "" to specify all templates. Uses "Everyone" to specify all requesters. Valid permission values are "Allow" and "Deny".

  "CertificateManagers":{
		"DOMAIN\\Username":{
			"Templates":{
				"MyTemplateShortName":{
					"Requesters":{
						"Everyone":"Allow",
						"DOMAIN\\Groupname":"Deny"
					}
				},
				"<All>":{
					"Requesters":{
						"Everyone":"Allow"
					}
				}
			}
		}
	}

  "CAConnection": {
	"AuthToken":"<auth token value>",
	"ClientCertificate": {
        "StoreName": "My",
        "StoreLocation": "LocalMachine",
        "Thumbprint": "0123456789abcdef"
    },
