Disclaimer
Azure SDK Python packages support for Python 2.7 has ended 01 January 2022. For more information and questions, please refer to https://github.com/Azure/azure-sdk-for-python/issues/20691.
Python 3.8 or later is required to use this package. For more details, please refer to Azure SDK for Python version support policy.
Getting started
Install the package
Install azure-keyvault-keys and
azure-identity with pip:
pip install azure-keyvault-keys azure-identity

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

An Azure subscription
Python 3.8 or later
An existing Azure Key Vault. If you need to create one, you can do so using the Azure CLI by following the steps in this document.
If using Managed HSM, an existing Key Vault Managed HSM. If you need to create a Managed HSM, you can do so using the Azure CLI by following the steps in this document.

Authenticate the client
In order to interact with the Azure Key Vault service, you will need an instance of a KeyClient, as
well as a vault URL and a credential object. This document demonstrates using a
DefaultAzureCredential, which is appropriate for most scenarios. 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 client
After configuring your environment for the DefaultAzureCredential to use a suitable method of
authentication, you can do the following to create a key client (replacing the value of VAULT_URL with your vault's
URL):

from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient

VAULT_URL = os.environ["VAULT_URL"]
credential = DefaultAzureCredential()
client = KeyClient(vault_url=VAULT_URL, credential=credential)



NOTE: For an asynchronous client, import azure.keyvault.keys.aio's KeyClient instead.

Key concepts
Keys
Azure Key Vault can create and store RSA and elliptic curve keys. Both can optionally be protected by hardware security
modules (HSMs). Azure Key Vault can also perform cryptographic operations with them. For more information about keys
and supported operations and algorithms, see the
Key Vault documentation.
KeyClient can create keys in the vault, get existing keys
from the vault, update key metadata, and delete keys, as shown in the
examples below.
Examples
This section contains code snippets covering common tasks:

Create a key
Retrieve a key
Update an existing key
Delete a key
Configure automatic key rotation
List keys
Perform cryptographic operations
Async API
Asynchronously create a key
Asynchronously list keys

Create a key
The create_key method can be
used by a KeyClient to create a key of any type -- alternatively, specific helpers such as
create_rsa_key and
create_ec_key
create RSA and elliptic curve keys in the vault, respectively. If a key with the same name already exists, a new version
of that key is created.
from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient

credential = DefaultAzureCredential()

key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)

# Create an RSA key
rsa_key = key_client.create_rsa_key("rsa-key-name", size=2048)
print(rsa_key.name)
print(rsa_key.key_type)

# Create an elliptic curve key
ec_key = key_client.create_ec_key("ec-key-name", curve="P-256")
print(ec_key.name)
print(ec_key.key_type)

Retrieve a key
get_key retrieves a key
previously stored in the Vault.
from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient

credential = DefaultAzureCredential()

key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
key = key_client.get_key("key-name")
print(key.name)

Update an existing key
update_key_properties
updates the properties of a key previously stored in the Key Vault.
from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient

credential = DefaultAzureCredential()

key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)

# we will now disable the key for further use
updated_key = key_client.update_key_properties("key-name", enabled=False)

print(updated_key.name)
print(updated_key.properties.enabled)

Delete a key
begin_delete_key
requests Key Vault delete a key, returning a poller which allows you to wait for the deletion to finish. Waiting is
helpful when the vault has soft-delete enabled, and you want to purge (permanently delete) the key as
soon as possible. When soft-delete is disabled, begin_delete_key itself is permanent.
from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient

credential = DefaultAzureCredential()

key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
deleted_key = key_client.begin_delete_key("key-name").result()

print(deleted_key.name)
print(deleted_key.deleted_date)

Configure automatic key rotation
update_key_rotation_policy
can be used by a KeyClient to configure automatic key rotation for a key by specifying a rotation policy.

from azure.keyvault.keys import KeyRotationLifetimeAction, KeyRotationPolicy, KeyRotationPolicyAction

# Here we set the key's automated rotation policy to rotate the key two months after the key was created.
# If you pass an empty KeyRotationPolicy() as the `policy` parameter, the rotation policy will be set to the
# default policy. Any keyword arguments will update specified properties of the policy.
actions = [KeyRotationLifetimeAction(KeyRotationPolicyAction.rotate, time_after_create="P2M")]
updated_policy = client.update_key_rotation_policy(
"rotation-sample-key", policy=KeyRotationPolicy(), expires_in="P90D", lifetime_actions=actions
)
assert updated_policy.expires_in == "P90D"


In addition,
rotate_key
allows you to rotate a key on-demand by creating a new version of the given key.

rotated_key = client.rotate_key("rotation-sample-key")
print(f"Rotated the key on-demand; new version is {rotated_key.properties.version}")


List keys
list_properties_of_keys
lists the properties of all of the keys in the client's vault.
from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient

credential = DefaultAzureCredential()

key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
keys = key_client.list_properties_of_keys()

for key in keys:
# the list doesn't include values or versions of the keys
print(key.name)

Cryptographic operations
CryptographyClient
enables cryptographic operations (encrypt/decrypt, wrap/unwrap, sign/verify) using a particular key.
from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient
from azure.keyvault.keys.crypto import CryptographyClient, EncryptionAlgorithm

credential = DefaultAzureCredential()
key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)

key = key_client.get_key("key-name")
crypto_client = CryptographyClient(key, credential=credential)
plaintext = b"plaintext"

result = crypto_client.encrypt(EncryptionAlgorithm.rsa_oaep, plaintext)
decrypted = crypto_client.decrypt(result.algorithm, result.ciphertext)

See the
package documentation
for more details of the cryptography API.
Async API
This library includes a complete set of async APIs. To use them, you must
first install an async transport, such as aiohttp.
See
azure-core documentation
for more information.
Async clients and credentials should be closed when they're no longer needed. These
objects are async context managers and define async close methods. For
example:
from azure.identity.aio import DefaultAzureCredential
from azure.keyvault.keys.aio import KeyClient

credential = DefaultAzureCredential()

# call close when the client and credential are no longer needed
client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
...
await client.close()
await credential.close()

# alternatively, use them as async context managers (contextlib.AsyncExitStack can help)
client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
async with client:
async with credential:
...

Asynchronously create a key
create_rsa_key and
create_ec_key
create RSA and elliptic curve keys in the vault, respectively. If a key with the same name already exists, a new
version of the key is created.
from azure.identity.aio import DefaultAzureCredential
from azure.keyvault.keys.aio import KeyClient

credential = DefaultAzureCredential()
key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)

# Create an RSA key
rsa_key = await key_client.create_rsa_key("rsa-key-name", size=2048)
print(rsa_key.name)
print(rsa_key.key_type)

# Create an elliptic curve key
ec_key = await key_client.create_ec_key("ec-key-name", curve="P-256")
print(ec_key.name)
print(ec_key.key_type)

Asynchronously list keys
list_properties_of_keys
lists the properties of all of the keys in the client's vault.
from azure.identity.aio import DefaultAzureCredential
from azure.keyvault.keys.aio import KeyClient

credential = DefaultAzureCredential()
key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
keys = key_client.list_properties_of_keys()

async for key in keys:
print(key.name)

Troubleshooting
See the azure-keyvault-keys
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 key that doesn't exist in the vault, KeyClient
raises ResourceNotFoundError:
from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient
from azure.core.exceptions import ResourceNotFoundError

credential = DefaultAzureCredential()
key_client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)

try:
key_client.get_key("which-does-not-exist")
except ResourceNotFoundError as e:
print(e.message)

Logging
This library uses the standard
logging library for logging.
Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO
level.
Detailed DEBUG level logging, including request/response bodies and unredacted
headers, can be enabled on a client with the logging_enable argument:
from azure.identity import DefaultAzureCredential
from azure.keyvault.keys import KeyClient
import sys
import logging

# Create a logger for the 'azure' SDK
logger = logging.getLogger('azure')
logger.setLevel(logging.DEBUG)

# Configure a console output
handler = logging.StreamHandler(stream=sys.stdout)
logger.addHandler(handler)

credential = DefaultAzureCredential()

# This client will log detailed information about its HTTP sessions, at DEBUG level
client = KeyClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential, logging_enable=True)

Similarly, logging_enable can enable detailed logging for a single operation,
even when it isn't enabled for the client:
client.get_key("my-key", logging_enable=True)

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

Create/get/update/delete keys (async version)
Basic list operations for keys (async version)
Back up and recover keys (async version)
Recover and purge keys (async version)
Create/update key rotation policies and rotate keys on-demand (async version)
Use the send_request client method

as a context manager, a KeyClient closes opened sockets on exit.
(#9906)
Pollers no longer sleep after operation completion
(#9991)

4.0.1 (2020-02-11)

azure.keyvault.keys defines __version__
Challenge authentication policy preserves request options
(#8999)
Updated msrest requirement to >=0.6.0
Challenge authentication policy requires TLS
(#9457)
Methods no longer raise the internal error KeyVaultErrorException
(#9690)
Fix AttributeError in async CryptographyClient when verifying signatures remotely
(#9734)

4.0.0 (2019-10-31)
Breaking changes:

Removed KeyClient.get_cryptography_client() and CryptographyClient.get_key()
Moved the optional parameters of several methods into kwargs (
docs
detail the new keyword arguments):

create_key now has positional parameters name and key_type
create_ec_key and create_rsa_key now have one positional parameter, name
update_key_properties now has two positional parameters, name and
(optional) version
import_key now has positional parameters name and key


CryptographyClient operations return class instances instead of tuples and renamed the following
properties

Renamed the decrypted_bytes property of DecryptResult to plaintext
Renamed the unwrapped_bytes property of UnwrapResult to key
Renamed the result property of VerifyResult to is_valid


Renamed the UnwrapKeyResult and WrapKeyResult classes to UnwrapResult and WrapResult
Renamed list_keys to list_properties_of_keys
Renamed list_key_versions to list_properties_of_key_versions
Renamed sync method delete_key to begin_delete_key
The sync method begin_delete_key and async delete_key now return pollers that return a DeletedKey
Renamed Key to KeyVaultKey
KeyVaultKey properties created, expires, and updated renamed to created_on,
expires_on, and updated_on
The vault_endpoint parameter of KeyClient has been renamed to vault_url
The property vault_endpoint has been renamed to vault_url in all models

New features:

Now all CryptographyClient returns include key_id and algorithm properties

4.0.0b4 (2019-10-08)


Enums JsonWebKeyCurveName, JsonWebKeyOperation, and JsonWebKeyType have
been renamed to KeyCurveName, KeyOperation, and KeyType, respectively.


Key now has attribute properties, which holds certain properties of the
key, such as version. This changes the shape of the returned Key type,
as certain properties of Key (such as version) have to be accessed
through the properties property.


update_key has been renamed to update_key_properties


The vault_url parameter of KeyClient has been renamed to vault_endpoint


The property vault_url has been renamed to vault_endpoint in all models


Fixes and improvements:

The key argument to import_key should be an instance of azure.keyvault.keys.JsonWebKey
(#7590)

4.0.0b3 (2019-09-11)
Breaking changes:

CryptographyClient methods wrap and unwrap are renamed wrap_key and
unwrap_key, respectively.

New features:

CryptographyClient performs encrypt, verify and wrap operations locally
when its key's public material is available (i.e., when it has keys/get
permission).

4.0.0b2 (2019-08-06)
Breaking changes:

Removed azure.core.Configuration from the public API in preparation for a
revamped configuration API. Static create_config methods have been renamed
_create_config, and will be removed in a future release.
Removed wrap_key and unwrap_key from KeyClient. These are now available
through CryptographyClient.
This version of the library requires azure-core 1.0.0b2

If you later want to revert to a version requiring azure-core 1.0.0b1,
of this or another Azure SDK library, you must explicitly install azure-core
1.0.0b1 as well. For example:
pip install azure-core==1.0.0b1 azure-keyvault-keys==4.0.0b1



New features:

Added CryptographyClient, a client for performing cryptographic operations
(encrypt/decrypt, wrap/unwrap, sign/verify) with a key.
Distributed tracing framework OpenCensus is now supported
Added support for HTTP challenge based authentication, allowing clients to
interact with vaults in sovereign clouds.

Other changes:

Async clients use aiohttp for transport
by default. See
azure-core documentation
for more information about using other transports.

4.0.0b1 (2019-06-28)
Version 4.0.0b1 is the first preview of our efforts to create a user-friendly
and Pythonic client library for Azure Key Vault. For more information about
preview releases of other Azure SDK libraries, please visit
https://aka.ms/azure-sdk-preview1-python.
This library is not a direct replacement for azure-keyvault. Applications
using that library would require code changes to use azure-keyvault-keys.
This package's
documentation
and
samples
demonstrate the new API.
Major changes from azure-keyvault

Packages scoped by functionality

azure-keyvault-keys contains a client for key operations,
azure-keyvault-secrets contains a client for secret operations


Client instances are scoped to vaults (an instance interacts with one vault
only)
Asynchronous API supported on Python 3.5.3+

the azure.keyvault.keys.aio namespace contains an async equivalent of
the synchronous client in azure.keyvault.keys


Authentication using azure-identity credentials

see this package's
documentation
, and the
Azure Identity documentation
for more information
