   $cert_url = <FQDN for the certificate> $cert_sans = @("<certificate SAN #1>","<certificate SAN #2>",...) $cert_ipaddrs = @("<certificate IP address #1>","<certificate IP address #2>",...)

5. In the same administrative PowerShell session, run one of the following:

   • For VMware SSL certificates, run the following: 

     $cert_template = "VMwareSSL6.5"

6. In the same administrative PowerShell prompt, run the following to create the INF file then open the INF file to review the output: 

   $cert_file = $cert_url + "_" + (Get-Date -Format yyyyMMdd-HHmmss) $cert_file_inf = ((Get-Location).Path + "\" + $cert_file + ".inf") $cert_file_content = @" [Version] Signature=`"`$Windows NT`$`" [NewRequest] Subject=`"CN=$cert_url`" Exportable=TRUE MachineKeySet=TRUE KeyLength=2048 [Extensions] 2.5.29.17=`"{text}`" _continue_=`"DNS=$cert_url&`" "@ New-Item $cert_file_inf -Type File -Force Set-Content $cert_file_inf $cert_file_content

7. In the same administrative PowerShell prompt, run the following to add any DNS subject alternate names to the INF file:
