Question

By following this,
Install certificate with PowerShell on remote server
I'm trying to install a pfx certificate on a remote server by using the following Powershell command,
Invoke-command -ComputerName myservername -scriptblock { Import-PfxCertificate –FilePath D:\pfxcert.pfx cert:\localMachine\my -Password (ConvertTo-SecureString -String "mypassword" -Force –AsPlainText) }
This is giving below error message for me...
The term 'Import-PfxCertificate' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
+ CategoryInfo : ObjectNotFound: (Import-PfxCertificate:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
+ PSComputerName : myservername
Please help me out on this.

Answer 1

The Cmdlet Import-PfxCertificate is part of the module PKIClient.
The PKI Client Cmdlets in Windows PowerShell are only available on
Windows 8.1
Windows PowerShell 4.0
Windows Server 2012 R2
Try to load the PKI Client in your Script:
Invoke-command -ComputerName myservername -scriptblock
{
Get-Command -Module PKIClient;
Import-PfxCertificate –FilePath D:\pfxcert.pfx cert:\localMachine\my -Password (ConvertTo-SecureString -String "mypassword" -Force –AsPlainText)
}
You could try Get-Command -Module PKIClient to see all cmdlets.

Answer 2

The Import-PfxCertificate cmdlet does not exist on the target machine. Probably because it is running a version of Powershell less than 3.
You'll have to install a newer version of PowerShell if possible, or find a different method of importing the certificate.

Answer 3

Well, if you need to call it from C# anyway, then it will be probably worth to install it from C#, like
using System.Security.Cryptography.X509Certificates;
X509Certificate2 certificate = new X509Certificate2("C:\TEMP\yourcerthere.pfx", "yourpasswordhere");
X509Store store = new X509Store(StoreName.TrustedPublisher, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadWrite);
store.Add(certificate);
store.Close();
It will be approx the same code in powershell actually, since it's no other way but use .net system class or some tool like this.
