Quickstart: Set and retrieve a certificate from Azure Key Vault using Azure PowerShell
In this quickstart, you create a key vault in Azure Key Vault with Azure PowerShell. Azure Key Vault is a cloud service that works as a secure secrets store. You can securely store keys, passwords, certificates, and other secrets. For more information on Key Vault you may review the Overview. Azure PowerShell is used to create and manage Azure resources using commands or scripts. Once that you have completed that, you will store a certificate.
If you don't have an Azure subscription, create a free account before you begin.
Azure Cloud Shell
Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. You can use either Bash or PowerShell with Cloud Shell to work with Azure services. You can use the Cloud Shell preinstalled commands to run the code in this article, without having to install anything on your local environment.
To start Azure Cloud Shell:
|Select Try It in the upper-right corner of a code or command block. Selecting Try It doesn't automatically copy the code or command to Cloud Shell.|
|Go to https://shell.azure.com, or select the Launch Cloud Shell button to open Cloud Shell in your browser.|
|Select the Cloud Shell button on the menu bar at the upper right in the Azure portal.|
To use Azure Cloud Shell:
Start Cloud Shell.
Select the Copy button on a code block (or command block) to copy the code or command.
Paste the code or command into the Cloud Shell session by selecting Ctrl+Shift+V on Windows and Linux, or by selecting Cmd+Shift+V on macOS.
Select Enter to run the code or command.
If you choose to install and use PowerShell locally, this tutorial requires Azure PowerShell module version 1.0.0 or later. Type
$PSVersionTable.PSVersion to find the version. If you need to upgrade, see Install Azure PowerShell module. If you are running PowerShell locally, you also need to run
Login-AzAccount to create a connection with Azure.
Create a resource group
A resource group is a logical container into which Azure resources are deployed and managed. Use the Azure PowerShell New-AzResourceGroup cmdlet to create a resource group named myResourceGroup in the eastus location.
New-AzResourceGroup -Name "myResourceGroup" -Location "EastUS"
Create a key vault
Use the Azure PowerShell New-AzKeyVault cmdlet to create a Key Vault in the resource group from the previous step. You will need to provide some information:
Key vault name: A string of 3 to 24 characters that can contain only numbers (0-9), letters (a-z, A-Z), and hyphens (-)
Each key vault must have a unique name. Replace <your-unique-keyvault-name> with the name of your key vault in the following examples.
Resource group name: myResourceGroup.
The location: EastUS.
New-AzKeyVault -Name "<your-unique-keyvault-name>" -ResourceGroupName "myResourceGroup" -Location "EastUS"
The output of this cmdlet shows properties of the newly created key vault. Take note of the two properties listed below:
- Vault Name: The name you provided to the -Name parameter above.
- Vault URI: In the example, this is https://<your-unique-keyvault-name>.vault.azure.net/. Applications that use your vault through its REST API must use this URI.
At this point, your Azure account is the only one authorized to perform any operations on this new vault.
Add a certificate to Key Vault
To add a certificate to the vault, you just need to take a couple of additional steps. This certificate could be used by an application.
Type the commands below to create a self-signed certificate with policy called ExampleCertificate :
$Policy = New-AzKeyVaultCertificatePolicy -SecretContentType "application/x-pkcs12" -SubjectName "CN=contoso.com" -IssuerName "Self" -ValidityInMonths 6 -ReuseKeyOnRenewal Add-AzKeyVaultCertificate -VaultName "<your-unique-keyvault-name>" -Name "ExampleCertificate" -CertificatePolicy $Policy
You can now reference this certificate that you added to Azure Key Vault by using its URI. Use
https://<your-unique-keyvault-name>.vault.azure.net/certificates/ExampleCertificate to get the current version.
To view previously stored certificate:
Get-AzKeyVaultCertificate -VaultName "<your-unique-keyvault-name>" -Name "ExampleCertificate"
Now, you have created a Key Vault, stored a certificate, and retrieved it.
Operation returned an invalid status code 'Forbidden'
If you receive this error, the account accessing the Azure Key Vault does not have the proper permissions to create certificates.
Run the following Azure PowerShell command to assign the proper permissions:
Set-AzKeyVaultAccessPolicy -VaultName <KeyVaultName> -ObjectId <AzureObjectID> -PermissionsToCertificates get,list,update,create
Clean up resources
Other quickstarts and tutorials in this collection build upon this quickstart. If you plan to continue on to work with other quickstarts and tutorials, you may want to leave these resources in place.
When no longer needed, you can use the Azure PowerShell Remove-AzResourceGroup cmdlet to remove the resource group and all related resources.
Remove-AzResourceGroup -Name "myResourceGroup"
In this quickstart you created a Key Vault and stored a certificate in it. To learn more about Key Vault and how to integrate it with your applications, continue on to the articles below.
