Use the VMware Validated Design Certificate Generation Utility (CertGenVVD) to generate certificates that are signed by the Microsoft certificate authority (MSCA) for all life cycle products with a single operation.

About this task

For information about the VMware Validated Design Certificate Generation Utility, see VMware Knowledge Base article 2146215 and the VMware Validated Design Planning and Preparation.


  • Provide a Window Server 2012 host that is part of the sfo01.rainpole.local domain.

  • Install a Certificate Authority server on the rainpole.local domain.


  1. Log in to a Windows host that has access to your data center.
  2. Download the file of the Certificate Generation Utility from VMware Knowledge Base article 2146215 on the Windows host where you connect to the data center and extract the ZIP file to the C: drive.
  3. In the C:\CertGenVVD-version folder, open the default.txt file in a text editor.
  4. Verify that following properties are configured.
    ORG=Rainpole Inc.
  5. Verify that the C:\CertGenVVD-version\ConfigFiles folder contains only following files.

    • sfo01vrli01b.sfo01.rainpole.local

    • sfo01vrli01c.sfo01.rainpole.local


  6. Verify that each configuration file includes FQDNs and host names in the dedicated sections.
  7. Open a Windows PowerShell prompt and navigate to the CertGenVVD folder.
    cd C:\CertGenVVD-version
  8. Grant permissions to run third-party PowerShell scripts.
    Set-ExecutionPolicy Unrestricted
  9. Validate if you can run the utility using the configuration on the host and verify if VMware is included in the printed CA template policy.
    .\CertgenVVD-version.ps1 -validate
  10. Generate MSCA-signed certificates.
    .\CertGenVVD-version.ps1 -MSCASigned -attrib 'CertificateTemplate:VMware'
  11. In the C:\CertGenVVD-version folder, verify that the utility created the SignedByMSCACerts sub-folder.
