Choosing a key modulus greater than 512 may take a few minutes. I have to generate two keys (private and public) to encrypt a text with the public and let the user with the private key decrypt the text. How to create a pair private/public keys using Node.js crypto? Ask Question Asked 8 years. Most servers run on Linux, I guess I'll make this a temporary solution untill nodejs supports RSA key. API principles¶. Asymmetric keys are represented by Python objects. Each object can be either a private key or a public key (the method hasprivate can be used to distinguish them). A key object can be created in four ways: generate at the module level (e.g. Crypto.PublicKey.RSA.generate).The key is randomly created each time.
-->Azure managed disks automatically encrypt your data by default when persisting it to the cloud. Server-side encryption protects your data and helps you meet your organizational security and compliance commitments. Data in Azure managed disks is encrypted transparently using 256-bit AES encryption, one of the strongest block ciphers available, and is FIPS 140-2 compliant.
Encryption does not impact the performance of managed disks. There is no additional cost for the encryption.
For more information about the cryptographic modules underlying Azure managed disks, see Cryptography API: Next Generation
About encryption key management
You can rely on platform-managed keys for the encryption of your managed disk, or you can manage encryption using your own keys. If you choose to manage encryption with your own keys, you can specify a customer-managed key to use for encrypting and decrypting all data in managed disks.
The following sections describe each of the options for key management in greater detail.
Platform-managed keys
By default, managed disks use platform-managed encryption keys. As of June 10, 2017, all new managed disks, snapshots, images, and new data written to existing managed disks are automatically encrypted-at-rest with platform-managed keys.
Customer-managed keys
You can choose to manage encryption at the level of each managed disk, with your own keys. Server-side encryption for managed disks with customer-managed keys offers an integrated experience with Azure Key Vault. You can either import your RSA keys to your Key Vault or generate new RSA keys in Azure Key Vault.
Azure managed disks handles the encryption and decryption in a fully transparent fashion using envelope encryption. It encrypts data using an AES 256 based data encryption key (DEK), which is, in turn, protected using your keys. The Storage service generates data encryption keys and encrypts them with customer-managed keys using RSA encryption. The envelope encryption allows you to rotate (change) your keys periodically as per your compliance policies without impacting your VMs. When you rotate your keys, the Storage service re-encrypts the data encryption keys with the new customer-managed keys.
You have to grant access to managed disks in your Key Vault to use your keys for encrypting and decrypting the DEK. This allows you full control of your data and keys. You can disable your keys or revoke access to managed disks at any time. You can also audit the encryption key usage with Azure Key Vault monitoring to ensure that only managed disks or other trusted Azure services are accessing your keys.
For premium SSDs, standard SSDs, and standard HDDs: When you disable or delete your key, any VMs with disks using that key will automatically shut down. After this, the VMs will not be usable unless the key is enabled again or you assign a new key.
For ultra disks, when you disable or delete a key, any VMs with ultra disks using the key won't automatically shut down. Once you deallocate and restart the VMs then the disks will stop using the key and then VMs won't come back online. To bring the VMs back online, you must assign a new key or enable the existing key.

The following diagram shows how managed disks use Azure Active Directory and Azure Key Vault to make requests using the customer-managed key:
The following list explains the diagram in more detail:
- An Azure Key Vault administrator creates key vault resources.
- The key vault admin either imports their RSA keys to Key Vault or generate new RSA keys in Key Vault.
- That administrator creates an instance of Disk Encryption Set resource, specifying an Azure Key Vault ID and a key URL. Disk Encryption Set is a new resource introduced for simplifying the key management for managed disks.
- When a disk encryption set is created, a system-assigned managed identity is created in Azure Active Directory (AD) and associated with the disk encryption set.
- The Azure key vault administrator then grants the managed identity permission to perform operations in the key vault.
- A VM user creates disks by associating them with the disk encryption set. The VM user can also enable server-side encryption with customer-managed keys for existing resources by associating them with the disk encryption set.
- Managed disks use the managed identity to send requests to the Azure Key Vault.
- For reading or writing data, managed disks sends requests to Azure Key Vault to encrypt (wrap) and decrypt (unwrap) the data encryption key in order to perform encryption and decryption of the data.
To revoke access to customer-managed keys, see Azure Key Vault PowerShell and Azure Key Vault CLI. Revoking access effectively blocks access to all data in the storage account, as the encryption key is inaccessible by Azure Storage.
Supported regions
For premium SSDs, standard SSDs, and standard HDDs, only the following regions currently support customer-managed keys:
- Available as a GA offering in the public regions and Azure Government regions.
For ultra disks, only the following regions support customer-managed keys as a GA offering:
- East US
- West US 2
Restrictions
For now, customer-managed keys have the following restrictions:
- If this feature is enabled for your disk, you cannot disable it.If you need to work around this, you must copy all the data to an entirely different managed disk that isn't using customer-managed keys.
- Only 'soft' and 'hard' RSA keys of size 2080 are supported, no other keys or sizes.
- Disks created from custom images that are encrypted using server-side encryption and customer-managed keys must be encrypted using the same customer-managed keys and must be in the same subscription.
- Snapshots created from disks that are encrypted with server-side encryption and customer-managed keys must be encrypted with the same customer-managed keys.
- Custom images encrypted using server-side encryption and customer-managed keys cannot be used in the shared image gallery.
- All resources related to your customer-managed keys (Azure Key Vaults, disk encryption sets, VMs, disks, and snapshots) must be in the same subscription and region.
- Disks, snapshots, and images encrypted with customer-managed keys cannot move to another subscription.
- If you use the Azure portal to create your disk encryption set, you cannot use snapshots for now.
- Managed disks encrypted using customer-managed keys cannot also be encrypted with Azure Disk Encryption.
PowerShell
Setting up your Azure Key Vault and DiskEncryptionSet
- Make sure that you have installed latest Azure PowerShell version, and you are signed in to an Azure account in with Connect-AzAccount
- Create an instance of Azure Key Vault and encryption key.When creating the Key Vault instance, you must enable soft delete and purge protection. Soft delete ensures that the Key Vault holds a deleted key for a given retention period (90 day default). Purge protection ensures that a deleted key cannot be permanently deleted until the retention period lapses. These settings protect you from losing data due to accidental deletion. These settings are mandatory when using a Key Vault for encrypting managed disks.ImportantDo not camel case the region, if you do so you may experience problems when assigning additional disks to the resource in the Azure portal.
- Create an instance of a DiskEncryptionSet.
- Grant the DiskEncryptionSet resource access to the key vault.NoteIt may take few minutes for Azure to create the identity of your DiskEncryptionSet in your Azure Active Directory. If you get an error like 'Cannot find the Active Directory object' when running the following command, wait a few minutes and try again.

Important
Customer-managed keys rely on managed identities for Azure resources, a feature of Azure Active Directory (Azure AD). When you configure customer-managed keys, a managed identity is automatically assigned to your resources under the covers. If you subsequently move the subscription, resource group, or managed disk from one Azure AD directory to another, the managed identity associated with managed disks is not transferred to the new tenant, so customer-managed keys may no longer work. For more information, see Transferring a subscription between Azure AD directories.
Portal
Setting up customer-managed keys for your disks will require you to create resources in a particular order, if you're doing it for the first time. First, you will need to create and set up an Azure Key Vault.
Setting up your Azure Key Vault
- Sign into the Azure portal.
- Search for and select Key Vaults.ImportantYour Azure key vault, disk encryption set, VM, disks, and snapshots must all be in the same region and subscription for deployment to succeed.
- Select +Add to create a new Key Vault.
- Create a new resource group.
- Enter a key vault name, select a region, and select a pricing tier.
- Select Review + Create, verify your choices, then select Create.
- Once your key vault finishes deploying, select it.
- Select Keys under Settings.
- Select Generate/Import.
- Leave both Key Type set to RSA and RSA Key Size set to 2048.
- Fill in the remaining selections as you like and then select Create.
Setting up your disk encryption set
- Search for Disk Encryption Sets and select it.
- On the Disk Encryption Sets blade select +Add.
- Select your resource group, name your encryption set, and select the same region as your key vault.
- Select Key vault and key.
- Select the key vault and key you created previously, as well as the version.
- Press Select.
- Select Review + Create and then Create.
- Open the disk encryption set once it finishes creating and select the alert that pops up.
Two notifications should pop up and succeed. Doing this will allow you to use the disk encryption set with your key vault.
Deploy a VM
Now that you've created and set up your key vault and the disk encryption set, you can deploy a VM using the encryption.The VM deployment process is similar to the standard deployment process, the only differences are that you need to deploy the VM in the same region as your other resources and you opt to use a customer managed key.
- Search for Virtual Machines and select + Add to create a VM.
- On the Basic tab, select the same region as your disk encryption set and Azure Key Vault.
- Fill in the other values on the Basic tab as you like.
- On the Disks tab, select Encryption at rest with a customer-managed key.
- Select your disk encryption set in the Disk encryption set drop-down.
- Make the remaining selections as you like.
Enable on an existing disk
Caution
Enabling disk encryption on any disks attached to a VM will require that you stop the VM.
- Navigate to a VM that is in the same region as one of your disk encryption sets.
- Open the VM and select Stop.
- After the VM has finished stopping, select Disks and then select the disk you want to encrypt.
- Select Encryption and select Encryption at rest with a customer-managed key and then select your disk encryption set in the drop-down list.
- Select Save.
- Repeat this process for any other disks attached to the VM you'd like to encrypt.
- When your disks finish switching over to customer-managed keys, if there are no there no other attached disks you'd like to encrypt, you may start your VM.
Important
Customer-managed keys rely on managed identities for Azure resources, a feature of Azure Active Directory (Azure AD). When you configure customer-managed keys, a managed identity is automatically assigned to your resources under the covers. If you subsequently move the subscription, resource group, or managed disk from one Azure AD directory to another, the managed identity associated with managed disks is not transferred to the new tenant, so customer-managed keys may no longer work. For more information, see Transferring a subscription between Azure AD directories.
Server-side encryption versus Azure disk encryption
Azure Disk Encryption leverages the BitLocker feature of Windows and the DM-Crypt feature of Linux to encrypt managed disks with customer-managed keys within the guest VM. Server-side encryption with customer-managed keys improves on ADE by enabling you to use any OS types and images for your VMs by encrypting data in the Storage service.
