For overview information about Azure Key Vault, see What is Azure Key Vault? and Get started with Azure Key Vault
Prerequisites
To complete this tutorial, you must have the following:
- An existing key vault that you have been using.
- A pfx file stored on your hard drive.
- Azure PowerShell, minimum version of 2.1.0.
To install Azure PowerShell and associate it with your Azure subscription, see How to install and configure Azure PowerShell. If you have already installed Azure PowerShell and do not know the version, from the Azure PowerShell console, type (
Get-Module azure -ListAvailable).Version.
This tutorial is designed for Azure PowerShell beginners who understand the basic concepts, such as modules, cmdlets, and sessions but it also assumes that you are familiar with Azure Key Vault and have gone through Get started with Azure Key Vault.
Start an Azure PowerShell session and sign in to your Azure account with the following command:
In the pop-up browser window, enter your Azure account user name and password. Azure PowerShell will get all the subscriptions that are associated with this account and by default, uses the first one. If you have multiple subscriptions, you might have to specify a specific one that was used to create your Azure Key Vault. Type the following to see the subscriptions for your account:
Then, to specify the subscription that's associated with your key vault, type:
For more information about configuring Azure PowerShell, see How to install and configure Azure PowerShell.
In our first getting started tutorial, our key vault name was ContosoKeyVault, so we'll continue to use that name and store the details into a variable named vaultName and also set the name for certificate created in the end as ContosoFirstCertificate
A newly created Key Vault by default has following permissions set for the creator of the vault:
Keys: get, create, delete, list, update, import, backup,
Secrets: 'all'
Certificates: ‘all’
A vault which was created before the introduction of certificates won’t have any permissions. And in this exercise we are using a previously created key vault and hence, the user would need to set explicit permissions. Type following to give permissions for all operations:
PermissionsToCertificates can also be set selectively by allowing only certain operations on the certificates. The list of operations on which permissions can be set are ‘Get, Delete, List, Create, Import, ManageContacts, GetIssuers, ListIssuers, SetIssuers and ‘all’.
Import an existing certificate to key vault
To import an existing certificate, you must have the certificate in a .PFX or PEM file format. If necessary, export an installed certificate with the private key (.PFX format) and a strong password, and save your certificate to your C: drive in a file named clientcert.pfx that you want to upload to Azure Key Vault. Type the following to set the variable securepfxpwd for a password of 123 for the .PFX file:
Azure Key Vault Auto Generate Secrets
Then type the following to import the certificate from the .PFX file, which imports the certificate and monitors the lifetime of the certificate in the Key Vault service:
You can now reference this certificate that you created or uploaded to Azure Key Vault, by using its URI. Use https://ContosoKeyVault.vault.azure.net/certificates/ContosoFirstCertificate to always get the current version, and use https://ContosoKeyVault.vault.azure.net/certificates/ContosoFirstCertificate/24bb21dacfad4f178e3d00e9dd54c034 to get this specific version.
If you want to retrieve the pfx back i.e. the private key of the certificate then you use https://ContosoKeyVault.vault.azure.net/secrets/ContosoFirstCertificate to get the current version and use
https://ContosoKeyVault.vault.azure.net/secrets/ContosoFirstCertificate/24bb21dacfad4f178e3d00e9dd54c034
Create a self-signed certificate in key vault
To create certificates in key vault you will first create the certificate policy.
Type following to add a Self-Signed Certificate and use the above policy to be applied to create the certificate
Enroll programmatically from Public CA (Certificate Authority)
Azure Key Vault supports enrollment of certificates from Public CA such as DigiCert, and GlobalSign. Azure Key Vault goes on behalf of the user to enroll for certificates from one of the above issuers. In this process Issuer needs to authenticate the entity requesting the certificate and also authorize to receive the requested certificate. Each Issuer requires different set of information to do so and this needs to be set once in the Key Vault.
If you select DigiCert to be your certificate authority or Issuer to issue certificates then go through these one-time setup steps to configure DigiCert as one of the Issuer in your vault.
Note: Customer will need to have an existing account or go here to create one with DigiCert and get domains pre-vetted
If you select GlobalSign to be your Issuer then go through these one-time setup steps to configure GlobalSign as one of the Issuer in your vault.
Note: Customer will need to have an existing account or go here to create one with GlobalSign and get your domains pre-vetted
Download warcraft 3 frozen throne cd key generator v1 2. Create the certificate policy similar to creating the template that defines what needs to be in the certificate (SubjectName, SAN etc.), when to renew the certificate and from which Issuer the certificate is to be issued.
Request for a certificate based on the above set policy
Certificate enrollment in Key Vault is an asynchronous process. The Add-AzureKeyVaultCertificate will return back an operation object which will indicate the status of enrollment. You can poll the creation of Certificate till the status is returned as complete.
Once the certificate is created you can view at the newly issued certificate details by following cmdlet
Create a certificate manually and get signed by a CA
Azure Key Vault supports to create the certificate signing request with private-public key pair and get it signed by any Certificate Authority of your choice. It could be internal enterprise CA or external public CA.
First create the certificate policy. Key Vault will not enroll or renew the certificate from the Issuer on behalf of the user as CA chosen in this scenario is not a supported one and hence the IssuerName is set to Unknown.
Create the certificate signing request
The $certificateOperation.CertificateSigningRequest is the base4 encoded certificate signing request for the certificate. You can take this blob and dump into Issuer’s certificate request website or use tools such as certreq or openssl to get the certificate request signed and complete the process of generating a certificate.
After the certificate request has been signed by the Issuer, you can bring back the signed certificate usually a file with .cer extension and merge it with the initial private-public key created in Azure Key Vault
Retrieve pfx file & add password back
A typical scenario is that the application would need to pull the pfx of the certificate to the machine where it is going to consume the certificate. Here is an example on how an application can retrieve the pfx from Azure Key Vault to consume it.
If the certificate file needs to be stored on the hard disk then it is good practice to encrypt it with a password.
How To Create Secret In Azure Key Vault
Get public portion of Certificate from Certificates Endpoint
Type following to retrieve the certificate or the public portion and store in a file with *.cer extension.
Listing all the certificates from the management endpoint
For management purposes, you would want to know the certificates in your key vault and related information about it. You would retrieve these information by running following queries as below:
Azure Key Vault Auto Generate Secret Key
Azure Key Vault certificates are auto renewed as per the configured certificate policy. Certificate policy is set to either say how many days before expiry do you want to renew the certificate or at what percentage of the lifetime of the certificate. And the policy also needs to have the Issuer value set to a supported Certificate Authority. In case where Certificate Authority needs authorization and authentication details then those should be set while adding the Issuer to the key vault.
Auto-renewal of certificates can fail due to misconfigured values or it can fail due to lack of funds and at times lack of incomplete vetting of domains. In any of the cases the Azure Key Vault Certificate Contact gets notified with the error message. You can choose to rectify the misconfigured values or add the required funds to your contract so that Azure Key Vault can go ahead and re-attempt the renewal. There will be few instances where Azure key Vault will notify the customer that it is better to manually enroll for the certificate mainly when it is very close to expiry. In such cases, you should go through and add a certificate using one of the above options.
Few other commands that you might find useful for managing Azure Key Vault Certificate are:
Add-AzureKeyVaultCertificateContact -VaultName $vaultName -EmailAddress '[email protected]”The Add-AzureKeyVaultCertificateContact cmdlet adds a contact to an Azure Key Vault for certificate notifications. The contact receives updates about events such as certificate close to expiry, certificate renewed, and so on. These events are determined by the certificate policy.Stop-AzureKeyVaultCertificateOperation -VaultName $vaultName -Name $certificateName –ForceThis cmdlet cancels the certificate operation in process on the $certificateName object.Remove-AzureKeyVaultCertificate -VaultName $vaultName -Name $certificateNameExample how to remove a specific certificate.

Azure Key Vault helps solve the following problems:
- Secrets Management - Azure Key Vault can be used to Securely store and tightly control access to tokens, passwords, certificates, API keys, and other secrets
- Key Management - Azure Key Vault can also be used as a Key Management solution. Azure Key Vault makes it easy to create and control the encryption keys used to encrypt your data.
- Certificate Management - Azure Key Vault is also a service that lets you easily provision, manage, and deploy public and private Transport Layer Security/Secure Sockets Layer (TLS/SSL) certificates for use with Azure and your internal connected resources.
- Store secrets backed by Hardware Security Modules - The secrets and keys can be protected either by software or FIPS 140-2 Level 2 validated HSMs
Why use Azure Key Vault?
Centralize application secrets
Centralizing storage of application secrets in Azure Key Vault allows you to control their distribution. Key Vault greatly reduces the chances that secrets may be accidentally leaked. When using Key Vault, application developers no longer need to store security information in their application. Not having to store security information in applications eliminates the need to make this information part of the code. For example, an application may need to connect to a database. Instead of storing the connection string in the app's code, you can store it securely in Key Vault.
Your applications can securely access the information they need by using URIs. These URIs allow the applications to retrieve specific versions of a secret. There is no need to write custom code to protect any of the secret information stored in Key Vault.
Securely store secrets and keys
Secrets and keys are safeguarded by Azure, using industry-standard algorithms, key lengths, and hardware security modules (HSMs). The HSMs used are Federal Information Processing Standards (FIPS) 140-2 Level 2 validated.
Azure Key Vault Key Vs Secret
Access to a key vault requires proper authentication and authorization before a caller (user or application) can get access. Authentication establishes the identity of the caller, while authorization determines the operations that they are allowed to perform.
Authentication is done via Azure Active Directory. Authorization may be done via role-based access control (RBAC) or Key Vault access policy. RBAC is used when dealing with the management of the vaults and key vault access policy is used when attempting to access data stored in a vault.
Azure Key Vault Retrieve Secret
Azure Key Vaults may be either software- or hardware-HSM protected. For situations where you require added assurance you can import or generate keys in hardware security modules (HSMs) that never leave the HSM boundary. Microsoft uses nCipher hardware security modules. You can use nCipher tools to move a key from your HSM to Azure Key Vault.
Finally, Azure Key Vault is designed so that Microsoft does not see or extract your data.
Monitor access and use
Once you have created a couple of Key Vaults, you will want to monitor how and when your keys and secrets are being accessed. You can monitor activity by enabling logging for your vaults. You can configure Azure Key Vault to:
- Archive to a storage account.
- Stream to an event hub.
- Send the logs to Azure Monitor logs.
You have control over your logs and you may secure them by restricting access and you may also delete logs that you no longer need.
Simplified administration of application secrets
When storing valuable data, you must take several steps. Security information must be secured, it must follow a life cycle, and it must be highly available. Azure Key Vault simplifies the process of meeting these requirements by:
- Removing the need for in-house knowledge of Hardware Security Modules.
- Scaling up on short notice to meet your organization's usage spikes.
- Replicating the contents of your Key Vault within a region and to a secondary region. Data replication ensures high availability and takes away the need of any action from the administrator to trigger the failover.
- Providing standard Azure administration options via the portal, Azure CLI and PowerShell.
- Automating certain tasks on certificates that you purchase from Public CAs, such as enrollment and renewal.
In addition, Azure Key Vaults allow you to segregate application secrets. Applications may access only the vault that they are allowed to access, and they can be limited to only perform specific operations. You can create an Azure Key Vault per application and restrict the secrets stored in a Key Vault to a specific application and team of developers.
Integrate with other Azure services
Create Secret In Azure Key Vault
