Generate Private Key From Existing Csr

Posted By admin On 14.12.20

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. You must have selected either the Free or HSM (paid) subscription opti. $ openssl req -out codesigning.csr -key private.key -new Where private.key is the existing private key. As you can see you do not generate this CSR from your certificate (public key). Also you do not generate the 'same' CSR, just a new one to request a new certificate. All SSL Certificates require a private key to work. The private key is a separate file that’s used in the encryption/decryption of data sent between your server and the connecting clients. A private key is created by you—the certificate owner—when you request your certificate with a Certificate Signing Request (CSR). Jul 16, 2015  If you don't have the private key, the only thing you can do is generate a new CSR (which will generate a new key) and re-issue the certificate.

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. Des key generation code in c. 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. /crysis-wars-cd-key-generator.html. Otherwise, to create a resource group you need to provide the pieces of information shown below:

EntityDescription Example
Resource Group NameThis is the name you choose for your Resource Group. ECSTestCertificatesGroup
LocationGeographic location for your key. Canada Central


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:

EntityDescription Example
VaultNameYour own Vault Name. This name is unique. Microsoft Azure will reject your Vault Name if someone else has already registered that name in the Cloud.MyNewECSKeyVault
ResourceGroupNameYour own Group Name (chosen in Step 3).ECSTestCertificatesGroup
LocationGeographic location for your key.Central Canada


How To Generate Private Key From Csr File

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:

EntityDescription Example
$vaultNameYour Vault Name.MyNewECSKeyVault
$CertificateNameYour own designated Certificate Friendly Name.MyCSCertificate
-subjectNameYour Fully Qualified Domain Name (FQDN).CN=www.testcertificates.com

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:

EntityDescription Example
$VaultNameYour Vault Name.MyNewECSKeyVault
$CertificateNameYour Certificate Friendly NameMyCSCertificate
FilePathLocation in your drive where you store your downloaded certificate file.C:azuretestServerCertificate.crt

Extract Private Key From Csr


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.
