use chilkat();

$cert = chilkat::CkCert->new();

# 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 == 0) {
    print $cert->lastErrorText() . "\r\n";
    exit;
}

$json = chilkat::CkJsonObject->new();

# 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 = chilkat::CkJsonObject->new();
$jsonOut->put_EmitCompact(0);
$success = $cert->UploadToCloud($json,$jsonOut);
if ($success == 0) {
    print $cert->lastErrorText() . "\r\n";
    print $jsonOut->emit() . "\r\n";
    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.
print $jsonOut->emit() . "\r\n";
print "Success" . "\r\n";

# Here is sample jsonOut
