Microsoft CA

General Information

This integrated user guide with MS CA (Microsoft Certificate Authority) has been prepared using the software and firmware versions below:

OS: Windows Server 2019 (English)
MS Certification Authority: 10.0
HSM firmware: 5.0.26.0 (or higher)
HSM client: 4.7.30 (or higher)

Requirements

Connectivity with the HSM (TCP port 4433).
HSM client software installed, (see Windows topic).
HSM service started.
Windows account with local administration permission.
Credentials of the HSM partition where the private key will be created or used.
You may need to restart Windows (to load the local machine settings).

Installation and configuration of MS CA with key generation in HSM

Configure the MS CAPI parameters with the HSM partition credentials in the GUI console (Dinamocon).
1. Configure the IP address, user and password of a partition in the HSM. The private key will be generated on this partition.
2. Select the Enable CNG option.
3. Click on the Apply button.
Note

Keep the Local Machine Configuration option unchecked and the CNG Compatibility Mode option checked.

MS CAPI configuration
Enable the MS CAPI parameters on a local machine in the GUI console (Dinamocon).

Enable the Local Machine Configuration option. Click the Apply button.

Note

Keep the Local Machine Configuration option checked and also the CNG Compatibility Mode option checked.

MS CAPI configuration, local machine
In the Windows Server Manager Dashboard, start the CA installation by clicking on Add Roles and Features

Dashboard Server Manager
Select the Role-based or feature-based installation type for the local computer.

Role-base installation

Server Selection
Select the Active Directory Certificate Services_role and confirm with _Add Feature.

Select Active Directory Certificate Services

List of tools for ADCS
Confirm the list of Features shown (no need to reselect). Click Next.
Read the installer's warning note. Note that the computer's domain name and settings cannot be changed once CA has been installed. Click Next.
Select other services to be installed in Active Directory Certificate Services. Other options can be selected according to the needs of each environment. For HSM integration purposes, only Certification Authority is required. Click Next.

Other services for ADCS
Confirm the summary of role, features and services information. Click on Install

Confirm installation
Once the installation is complete, the CA must be configured. This can be done on the installation completion screen or in the notification area of the Server Manager dashboard.

Completion of installation

During configuration it can be useful to leave the CLI console hsmcon.exe (command line) showing real-time HSM activity (option Logs/Follow) and verifying that the private key will be generated and used.
Check and confirm the Windows credentials that will be used in the service.

Confirmation of credentials for the service
Select the services to be configured. For HSM integration purposes, only the Certification Authority is required.

Services to be configured
Specify the type of AC setup. In this guide we are assuming the Standalone AC type.
Specify the type of CA. In this guide we are assuming the Root CA type.
Specify the type of private key as Create a new private key.

Type of private key
In the encryption options select the HSM RSA algorithm provider as the cryptopraphic provider Dinamo:

RSA#Dinamo HSM Cryptographic Provider

Select the size of the key and the hash algorithm for signing the certificates as defined by your specific environment. For example, 4096-bit RSA key and SHA256 hash algorithm.

Cryptographic Provder
Specify the Common Name for the CA. This name will be used on all certificates issued by the CA.

AC Common Name
Specify the validity period of the certificates issued by the CA. For example 01 year.
Specify the CA's storage and log and database locations.
Check and confirm the CA configuration information.

AC configuration confirmation
The ADCS service will generate an RSA private key in the HSM and complete the configuration process.

AC configuration confirmation

In the CA manager(Certification Authority) you can check the CA's information and details.

The HSM logs should show the generation of the private key and its use by ADCS during the CA configuration process. In the log example below, the RSA key was generated with the name DBB0823FF3A4C57A993829E486C81038. This is the CA's private key. It is recommended to immediately generate a backup of the HSM.

The details of the CA's private key can be checked in the HSM console.

Note

ADCS explicitly requests that the generated key be exportable.
