Purpose: How to create a Private Key, CSR and Import Certificate on Microsoft Azure KeyVault (Cloud HSM)

Requirements
1. You must have an active Microsoft Azure account.
2. You must have selected either the Free or HSM (paid) subscription option. These steps will work for either Microsoft Azure account type.
3. Microsoft Azure PowerShell must be installed. You can download it here.
The solution is in three parts:
1) Login and Create a Resource Group
2) Creating a Private Key and Certificate Signing Request (CSR)
3) Importing the Public Signed Certificate to Microsoft Azure KeyVault

1. Launch Microsoft Azure PowerShell.
2. Log in to your Microsoft Azure account by typing:
Login-AzureRmAccount
You will be prompted to enter your credentials to log in to your account. Once you login successfully you will see something like the below:
3. Determine your Resource Group. If you already have an existing Resource Group, you can skip this step. Otherwise, to create a resource group you need to provide the pieces of information shown below:

To create a new resource group, use the command below:
New-AzureRMResourceGroup -Name 'ECSTestCertificatesGroup' -Location 'Canada Central'
4. Determine your keyvault. If you do not have an existing keyvault, you will need to generate one.
To create a new keyvault follow the command line below:
New-AzureRmKeyVault -VaultName '<your Vault Name>' -ResourceGroupName '<your Group Name>' -Location '<your Location>' -SKU 'Premium'
Where:

You can issue a new FileVault 2 recovery key to computers with OS X v10.9–v10.11 that have FileVault 2 activated. This allows you to do the following: Update the recovery key on computers on a regular schedule, without needing to decrypt and then re-encrypt the computers. I have been trying to create a class which has a property for key value pair, I have tried the Dictionary keyword, but I need something like this: ClassName clsName = new ClassName; clsName.PropertyName.Add'Key' = value; I want it to be dynamic property so I can send any datatype. The FileVault option in macOS is a fantastic way to enhance the security of your data at rest. It’s full-disk encryption (FDE), meaning that your entire startup volume is locked away when macOS is shut down (not just sleeping) using strong encryption. This parameter is required when you create a new key. If you import a key by using the KeyFilePath parameter, this parameter is optional: If you do not specify this parameter, and this cmdlet imports a key that has.byok file name extension, it imports that key as an HSM-protected key. The cmdlet cannot import that key as software-protected key.

1. Make sure you are still logged into your Microsoft Azure account from PowerShell.
2. Set the parameters for your certificate policy by using the following commands:
$vaultName = '<your Vault Name>'
$certificateName = '<your Certificate Name>'
$manualPolicy = New-AzureKeyVaultCertificatePolicy -SubjectName '<your FQDN>' -ValidityInMonths 24 -IssuerName Unknown
Where:

3. Execute the Certificate Operation Command:
$certificateOperation = Add-AzureKeyVaultCertificate -VaultName $vaultName -Name $certificateName -CertificatePolicy $manualPolicy
Your private key has been generated. To view your private key inside KeyVault, use the command:
Get-AzureKeyVaultKey -VaultName 'MyNewECSKeyVault'
4. Generate Certificate Signing Request (CSR) by using the below command:
$certificateOperation.CertificateSigningRequest
You have successfully created the CSR and are ready to create the certificate. This is the CSR you will use to create the certificate in either your ECS Enterprise Account or during the ordering process if you are requesting an individual Code Signing certificate.

After completing the creation of your certificate using either your ECS Enterprise account, or by completing the individual certificate purchase on our website, follow these steps to successfully import the Public Signed Certificate to Microsoft Azure KeyVault:
1. Download your certificate, which will be delivered in a .zip format.
2. Unzip the file and store it to your local drive so you may import it to Microsoft Azure Keyvault.
3. Import the certificate to Microsoft Azure KeyVault using the command:
Import-AzureKeyVaultCertificate -VaultName $vaultName -Name $certificateName -FilePath
Where:

You have successfully imported your certificate into your Microsoft Azure KeyVault Cloud HSM.
Note that at this time Microsoft Azure does not allow direct signing from within keyvault. Applications that use a keyvault must authenticate by using a token from Azure Active Directory. That means the usage of keyvault is limited to Azure Cloud environment only and cannot be used for third party application outside this realm. For more information, see this article by Microsoft.
For best practices regarding the protection of private keys related to Code Signing certificates, please see our Best Practices article here.

Creates a new key, stores it, then returns key parameters and attributes to the client.
The create key operation can be used to create any key type in Azure Key Vault. If the named key already exists, Azure Key Vault creates a new version of the key. It requires the keys/create permission.
