Azure Key Vault Administration client library for Python

Note: The Administration library only works with Managed HSM – functions targeting a Key Vault will fail.

Azure Key Vault helps solve the following problems:

  • Vault administration (this library) - role-based access control (RBAC), and vault-level backup and restore options
  • Cryptographic key management (azure-keyvault-keys) - create, store, and control access to the keys used to encrypt your data
  • Secrets management (azure-keyvault-secrets) - securely store and control access to tokens, passwords, certificates, API keys, and other secrets
  • Certificate management (azure-keyvault-certificates) - create, manage, and deploy public and private SSL/TLS certificates

Getting started

Install packages

Install azure-keyvault-administration and azure-identity with pip:

pip install azure-keyvault-administration azure-identity

azure-identity is used for Azure Active Directory authentication as demonstrated below.

Prerequisites

Authenticate the client

In order to interact with the Azure Key Vault service, you will need an instance of either a KeyVaultAccessControlClient or KeyVaultBackupClient, as well as a vault url (which you may see as "DNS Name" in the Azure Portal) and a credential object. This document demonstrates using a DefaultAzureCredential, which is appropriate for most scenarios, including local development and production environments. We recommend using a managed identity for authentication in production environments.

See azure-identity documentation for more information about other methods of authentication and their corresponding credential types.

Create a KeyVaultAccessControlClient

After configuring your environment for the DefaultAzureCredential to use a suitable method of authentication, you can do the following to create an access control client (replacing the value of vault_url with your Managed HSM's URL):

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient

credential = DefaultAzureCredential()

client = KeyVaultAccessControlClient(
    vault_url="https://my-managed-hsm-name.managedhsm.azure.net/",
    credential=credential
)

NOTE: For an asynchronous client, import azure.keyvault.administration.aio's KeyVaultAccessControlClient instead.

Create a KeyVaultBackupClient

After configuring your environment for the DefaultAzureCredential to use a suitable method of authentication, you can do the following to create a backup client (replacing the value of vault_url with your Managed HSM's URL):

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultBackupClient

credential = DefaultAzureCredential()

client = KeyVaultBackupClient(
    vault_url="https://my-managed-hsm-name.managedhsm.azure.net/",
    credential=credential
)

NOTE: For an asynchronous client, import azure.keyvault.administration.aio's KeyVaultBackupClient instead.

Create a KeyVaultSettingsClient

After configuring your environment for the DefaultAzureCredential to use a suitable method of authentication, you can do the following to create a settings client (replacing the value of vault_url with your Managed HSM's URL):

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultSettingsClient

credential = DefaultAzureCredential()

client = KeyVaultSettingsClient(
    vault_url="https://my-managed-hsm-name.managedhsm.azure.net/",
    credential=credential
)

NOTE: For an asynchronous client, import azure.keyvault.administration.aio's KeyVaultSettingsClient instead.

Key concepts

Role definition

A role definition defines the operations that can be performed, such as read, write, and delete. It can also define the operations that are excluded from allowed operations.

A role definition is specified as part of a role assignment.

Role assignment

A role assignment is the association of a role definition to a service principal. They can be created, listed, fetched individually, and deleted.

KeyVaultAccessControlClient

A KeyVaultAccessControlClient manages role definitions and role assignments.

KeyVaultBackupClient

A KeyVaultBackupClient performs full key backups, full key restores, and selective key restores.

KeyVaultSettingsClient

A KeyVaultSettingsClient manages Managed HSM account settings.

Examples

This section contains code snippets covering common tasks:

List all role definitions

List the role definitions available for assignment.

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient, KeyVaultRoleScope

credential = DefaultAzureCredential()

client = KeyVaultAccessControlClient(
    vault_url="https://my-managed-hsm-name.managedhsm.azure.net/",
    credential=credential
)

# this will list all role definitions available for assignment
role_definitions = client.list_role_definitions(KeyVaultRoleScope.GLOBAL)

for definition in role_definitions:
    print(definition.id)
    print(definition.role_name)
    print(definition.description)

Set, get, and delete a role definition

set_role_definition can be used to either create a custom role definition or update an existing definition with the specified name.

import uuid
from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import (
    KeyVaultAccessControlClient,
    KeyVaultDataAction,
    KeyVaultPermission,
    KeyVaultRoleScope
)

credential = DefaultAzureCredential()

client = KeyVaultAccessControlClient(
    vault_url="https://my-managed-hsm-name.managedhsm.azure.net/",
    credential=credential
)

# create a custom role definition
permissions = [KeyVaultPermission(allowed_data_actions=[KeyVaultDataAction.READ_HSM_KEY])]
created_definition = client.set_role_definition(KeyVaultRoleScope.GLOBAL, permissions=permissions)

# update the custom role definition
permissions = [
    KeyVaultPermission(allowed_data_actions=[], denied_data_actions=[KeyVaultDataAction.READ_HSM_KEY])
]
updated_definition = client.set_role_definition(
    KeyVaultRoleScope.GLOBAL, permissions=permissions, role_name=created_definition.name
)

# get the custom role definition
definition = client.get_role_definition(KeyVaultRoleScope.GLOBAL, role_name=definition_name)

# delete the custom role definition
deleted_definition = client.delete_role_definition(KeyVaultRoleScope.GLOBAL, role_name=definition_name)

List all role assignments

Before creating a new role assignment in the next snippet, list all of the current role assignments:

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient, KeyVaultRoleScope

credential = DefaultAzureCredential()

client = KeyVaultAccessControlClient(
    vault_url="https://my-managed-hsm-name.managedhsm.azure.net/",
    credential=credential
)

# this will list all role assignments
role_assignments = client.list_role_assignments(KeyVaultRoleScope.GLOBAL)

for assignment in role_assignments:
    print(assignment.name)
    print(assignment.principal_id)
    print(assignment.role_definition_id)

Create, get, and delete a role assignment

Assign a role to a service principal. This will require a role definition ID and service principal object ID. You can use an ID from the retrieved list of role definitions for the former, and an assignment's principal_id from the list retrieved in the above snippet for the latter.

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient, KeyVaultRoleScope

credential = DefaultAzureCredential()

client = KeyVaultAccessControlClient(
    vault_url="https://my-managed-hsm-name.managedhsm.azure.net/",
    credential=credential
)

# Replace <role-definition-id> with the id of a definition from the fetched list from an earlier example
role_definition_id = "<role-definition-id>"
# Replace <service-principal-object-id> with the principal_id of an assignment returned from the previous example
principal_id = "<service-principal-object-id>"

# first, let's create the role assignment
role_assignment = client.create_role_assignment(KeyVaultRoleScope.GLOBAL, role_definition_id, principal_id)
print(role_assignment.name)
print(role_assignment.principal_id)
print(role_assignment.role_definition_id)

# now, we get it
role_assignment = client.get_role_assignment(KeyVaultRoleScope.GLOBAL, role_assignment.name)
print(role_assignment.name)
print(role_assignment.principal_id)
print(role_assignment.role_definition_id)

# finally, we delete this role assignment
role_assignment = client.delete_role_assignment(KeyVaultRoleScope.GLOBAL, role_assignment.name)
print(role_assignment.name)
print(role_assignment.principal_id)
print(role_assignment.role_definition_id)

Perform a full key backup

Back up your entire collection of keys. The backing store for full key backups is a blob storage container using Shared Access Signature authentication.

For more details on creating a SAS token using the BlobServiceClient, see the sample here. Alternatively, it is possible to generate a SAS token in Storage Explorer

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultBackupClient

credential = DefaultAzureCredential()
client = KeyVaultBackupClient(vault_url="https://my-managed-hsm-name.managedhsm.azure.net/", credential=credential)

# blob storage container URL, for example https://<account name>.blob.core.windows.net/backup
blob_storage_url = "<your-blob-storage-url>"
sas_token = "<your-sas-token>"  # replace with a sas token to your storage account

# Backup is a long-running operation. The client returns a poller object whose result() method
# blocks until the backup is complete, then returns an object representing the backup operation.
backup_poller = client.begin_backup(blob_storage_url, sas_token)
backup_operation = backup_poller.result()

# this is the Azure Storage Blob URL of the backup
print(backup_operation.folder_url)

Perform a full key restore

Restore your entire collection of keys from a backup. The data source for a full key restore is a storage blob accessed using Shared Access Signature authentication. You will also need the azure_storage_blob_container_uri from the above snippet.

For more details on creating a SAS token using the BlobServiceClient, see the sample here. Alternatively, it is possible to generate a SAS token in Storage Explorer

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultBackupClient

credential = DefaultAzureCredential()
client = KeyVaultBackupClient(vault_url="https://my-managed-hsm-name.managedhsm.azure.net/", credential=credential)

sas_token = "<your-sas-token>"  # replace with a sas token to your storage account

# URL to a storage blob, for example https://<account name>.blob.core.windows.net/backup/mhsm-account-2020090117323313
blob_url = "<your-blob-url>"

# Restore is a long-running operation. The client returns a poller object whose wait() method
# blocks until the restore is complete.
restore_poller = client.begin_restore(blob_url, sas_token)
restore_poller.wait()

Troubleshooting

See the azure-keyvault-administration troubleshooting guide for details on how to diagnose various failure scenarios.

General

Key Vault clients raise exceptions defined in azure-core. For example, if you try to get a role assignment that doesn't exist, KeyVaultAccessControlClient raises ResourceNotFoundError:

from azure.identity import DefaultAzureCredential
from azure.keyvault.administration import KeyVaultAccessControlClient
from azure.core.exceptions import ResourceNotFoundError

credential = DefaultAzureCredential()
client = KeyVaultAccessControlClient(vault_url="https://my-managed-hsm-name.managedhsm.azure.net/", credential=credential)

try:
    client.get_role_assignment("/", "which-does-not-exist")
except ResourceNotFoundError as e:
    print(e.message)

Clients from the Administration library can only be used to perform operations on a managed HSM, so attempting to do so on a Key Vault will raise an error.

Next steps

Several samples are available in the Azure SDK for Python GitHub repository. These samples provide example code for additional Key Vault scenarios:

File Description
access_control_operations.py create/update/delete role definitions and role assignments
access_control_operations_async.py create/update/delete role definitions and role assignments with an async client
backup_restore_operations.py full backup and restore
backup_restore_operations_async.py full backup and restore with an async client
settings_operations.py list and update Key Vault settings
settings_operations_async.py list and update Key Vault settings with an async client
