Chilkat .NET Downloads Chilkat .NET Assemblies

Add-Type -Path "C:\chilkat\ChilkatDotNet47-9.5.0-x64\ChilkatDotNet47.dll"

$cert = New-Object Chilkat.Cert

# The certificate must originate from a source where the private key material is available to be included
# in the upload to Azure Key Vault.

$success = $cert.LoadPfxFile("qa_data/pfx/myCert.pfx","pfx_password")
if ($success -eq $false) {
    $($cert.LastErrorText)
    exit
}

$json = New-Object Chilkat.JsonObject

# Indicate this request is to upload to Azure Key Vault.
$json.UpdateString("service","azure-keyvault")

# Provide your OAuth2 client credentials for your Azure App (service principal) that has
# the required Role-Based Access Control (RBAC) permissions.
$json.UpdateString("auth.client_id","APP_ID")
$json.UpdateString("auth.client_secret","APP_PASSWORD")
$json.UpdateString("auth.tenant_id","TENANT_ID")

# Indicate the key vault name
$json.UpdateString("vault_name","VAULT_NAME")

# When you import a certificate into an Azure Key Vault, the certificate name and vault name are included as 
# parts of the URL to specify the target location where the certificate should be stored. 
# The URL follows a specific format to identify the target Key Vault and the certificate within it. 
# Here's how the certificate name and vault name are incorporated into the URL:
# https://VAULT_NAME.vault.azure.net//certificates/CERT_NAME/import?api-version=7.4

# Specify an arbitrary certificate name, but one that can be used in a URL as shown above.  (i.e. alphanumeric with no SPACE chars)
$json.UpdateString("cert_name","CERT_NAME")

# Add optional tags if desired. Tags can be anything you want.   
$json.UpdateString("tags.serial",$cert.SerialNumber)
$json.UpdateString("tags.issuer",$cert.IssuerCN)
$json.UpdateString("tags.subject",$cert.SubjectCN)

# OK.. everything is specified.  Simply call UploadToCloud.
$jsonOut = New-Object Chilkat.JsonObject
$jsonOut.EmitCompact = $false
$success = $cert.UploadToCloud($json,$jsonOut)
if ($success -eq $false) {
    $($cert.LastErrorText)
    $($jsonOut.Emit())
    exit
}

# Success!  Go to the Azure portal and refresh to see the certificate has been uploaded.
# The jsonOut provides the JSON response from the Azure server.
$($jsonOut.Emit())
