![]() Replace the values for -ValutName and -ResourceGroupName. Now, you can associate Azure Resource Manager Service Principal to Key Vault instance. $azureRmADServicePrincipal = New-AzureRmADServicePrincipal -ApplicationId $azureRmADApplication.ApplicationId $azureRmADApplication = New-AzureRmADApplication -DisplayName "KeyVault Reader - Cert" -HomePage " -IdentifierUris " -CertValue $credValue -StartDate $startDate -EndDate $endDate Login-AzureRmAccount -SubscriptionId 00000000-0000-0000-0000-000000000000Īfter importing the certificate and casting Certificate Data to Base64, you are ready to create your Azure Resource Manager AD Application ( AzureRMAdApplication) and Service Principal ( AzureRmADServicePrincipal). $startYear and $endYear should match the X508Certificate dates. $credValue = ::ToBase64String($x509Cert.GetRawCertData())Īssign correct certificate date to PowerShell variable to use in future. $x509Cert = New-Object 509Certificates.X509Certificate2 Note: Azure Key Vault REST API interface would require Base64 encoding. The below command would create an X509Certificate2 instance and import newly created key. Get started with Azure PowerShell cmdlets If you are not familiarised with PowerShell cmdlets, then I would recommend you I have used PowerShell and Azure PowerShell cmdlets to configure and associate the certificate with Azure AD Application. pfx contains the All Keys and certificate chains and it should always be passphrase(password) protected.Ĭonfigure Azure AD and Associate the Certificate pvk contains the Private key and securely stored. cer contains the Public Key and usually distributed outside. Pvk2pfx -pvk nilayblogkey.pvk -spc nilayblogkey.cer -pfx nilayblogkey.pfx -po password123 Makecert -sv nilayblogkey.pvk -n "cn=NPBlogKVApp" nilayblogkey.cer -b -e -r * use developer command prompt if you see `command not found` errors */ I would simply demonstrate, how to create a self-signed. Azure Key Vault goes on behalf of the user to enroll for certificates from one of the above issuers. Referance Azure Key Vault and Managed PKIĪzure Key Vault supports enrollment of certificates from Public CA such as DigiCert, GlobalSign and WoSign. The scenario has limited impact in this context.You can still use other Managed PKI but they would require additional engineering and security efforts.Microsoft Azure Key Vault supports DigiCert, GlobalSign and WoSign. ![]() Obtain X509 Certificate from CA or Certification Management.Here are couple of options available to you, Configure Azure AD and Associate the Certificate.This is the very useful solution for B2C and B2B integrations.Īuthenticate with Certificate to Azure Key VaultĪzure AD Application authenticates to Key Vault by using a Client Id and an X509 Certificate instead of Client Secret. This would allow to localise Security Orchestration and minimise the scope. In a Hybrid Network or Multi-Tenant System scenario, certificates can be associated with Local AD and Groups. ![]() Client Secret would require additional configuration and efforts to achieve a similar level of orchestration.Ĭertificate reduce Attack Surface Area than Client Secret due to limited redundancy if implemented correctly.Ĭertificates simplify DevOps requirement, where CD/CI pipeline can generate or renew and delegate grunt job to Certificate Authority or Certificate Management would propagate the change throughout a cluster of machines. It is easy to revoke X509 Certificate in the event of security breach or compromise, and existing Security Orchestration configuration with CA or Certificate Provider could beneficial. While Certificates can be persisted securely in Local or Server Certificate Store, engineering efforts would be less with Certificate and it would be more secure. However, these are some key points,Ĭlient Secret is like a strong password and application would require employing adequate measures to store it safely for first-time use. I would do a detail blog post in future regarding the subject. There are some advantages that I see for using Certificate over Client Secret. To access Azure Key Vault securely, you can opt for either of the following options. Let’s move to next logical topic, how to access Azure Key Vault securely from client applications. In a previous post we have discussed options for setting up an Azure Key Vault.
