# Azure Key Vault Certificates client library for Python
Azure Key Vault helps solve the following problems:
- Certificate management (this library) - create, manage, and deploy public and private SSL/TLS certificates
- Cryptographic key management
([azure-keyvault-keys](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/keyvault/azure-keyvault-keys)) - create, store, and control access to the keys used to encrypt your data
- Secrets management
([azure-keyvault-secrets](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/keyvault/azure-keyvault-secrets)) -
securely store and control access to tokens, passwords, certificates, API keys,
and other secrets

[Source code][certificates_client_src] | [Package (PyPI)][pypi_package_certificates] | [API reference documentation][reference_docs] | [Product documentation][keyvault_docs] | [Samples][certificates_samples]

## Getting started
### Install the package
Install [azure-keyvault-certificates][pypi_package_certificates] and
[azure-identity][azure_identity] with [pip][pip]:
```Bash
pip install azure-keyvault-certificates azure-identity
```
[azure-identity][azure_identity] is used for Azure Active Directory
authentication as demonstrated below.

### Prerequisites
* An [Azure subscription][azure_sub]
* Python 2.7, 3.5.3, or later
* A Key Vault. If you need to create one, you can use the
[Azure Cloud Shell][azure_cloud_shell] to create one with these commands
(replace `"my-resource-group"` and `"my-key-vault"` with your own, unique
names):

  (Optional) if you want a new resource group to hold the Key Vault:
  ```sh
  az group create --name my-resource-group --location westus2
  ```

  Create the Key Vault:
  ```Bash
  az keyvault create --resource-group my-resource-group --name my-key-vault
  ```

  Output:
  ```json
  {
      "id": "...",
      "location": "westus2",
      "name": "my-key-vault",
      "properties": {
          "accessPolicies": [...],
          "createMode": null,
          "enablePurgeProtection": null,
          "enableSoftDelete": null,
          "enabledForDeployment": false,
          "enabledForDiskEncryption": null,
          "enabledForTemplateDeployment": null,
          "networkAcls": null,
          "provisioningState": "Succeeded",
          "sku": { "name": "standard" },
          "tenantId": "...",
          "vaultUri": "https://my-key-vault.vault.azure.net/"
      },
      "resourceGroup": "my-resource-group",
      "type": "Microsoft.KeyVault/vaults"
  }
  ```

  > The `"vaultUri"` property is the `vault_url` used by [CertificateClient][certificate_client_docs]

### Authenticate the client
This document demonstrates using [DefaultAzureCredential][default_cred_ref]
to authenticate as a service principal. However, [CertificateClient][certificate_client_docs]
accepts any [azure-identity][azure_identity] credential. See the
[azure-identity][azure_identity] documentation for more information about other
credentials.

#### Create a service principal (optional)
This [Azure Cloud Shell][azure_cloud_shell] snippet shows how to create a
new service principal. Before using it, replace "your-application-name" with
a more appropriate name for your service principal.

Create a service principal:
```Bash
az ad sp create-for-rbac --name http://my-application --skip-assignment
```

> Output:
> ```json
> {
>     "appId": "generated app id",
>     "displayName": "my-application",
>     "name": "http://my-application",
>     "password": "random password",
>     "tenant": "tenant id"
> }
> ```

Use the output to set **AZURE_CLIENT_ID** ("appId" above), **AZURE_CLIENT_SECRET**
("password" above) and **AZURE_TENANT_ID** ("tenant" above) environment variables.
The following example shows a way to do this in Bash:
```Bash
export AZURE_CLIENT_ID="generated app id"
export AZURE_CLIENT_SECRET="random password"
export AZURE_TENANT_ID="tenant id"
```

Authorize the service principal to perform certificate operations in your Key Vault:
```Bash
az keyvault set-policy --name my-key-vault --spn $AZURE_CLIENT_ID --certificate-permissions backup create delete get import list purge recover restore update
```
> Possible certificate permissions: backup, create, delete, deleteissuers, get, getissuers, import, list, listissuers, managecontacts, manageissuers, purge, recover, restore, setissuers, update

#### Create a client
Once the **AZURE_CLIENT_ID**, **AZURE_CLIENT_SECRET** and
**AZURE_TENANT_ID** environment variables are set,
[DefaultAzureCredential][default_cred_ref] will be able to authenticate the
[CertificateClient][certificate_client_docs].

Constructing the client also requires your vault's URL, which you can
get from the Azure CLI or the Azure Portal. In the Azure Portal, this URL is
the vault's "DNS Name".

```python
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient

credential = DefaultAzureCredential()

certificate_client = CertificateClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
```

## Key concepts
With a [CertificateClient][certificate_client_docs] you can get certificates from the vault, create new certificates and
new versions of existing certificates, update certificate metadata, and delete certificates. You
can also manage certificate issuers, contacts, and management policies of certificates. This is
illustrated in the [examples](#examples) below.

### Certificate Client:

## Examples
This section contains code snippets covering common tasks:
* [Create a Certificate](#create-a-certificate "Create a Certificate")
* [Retrieve a Certificate](#retrieve-a-certificate "Retrieve a Certificate")
* [Update Properties of an existing Certificate](#update-properties-of-an-existing-certificate "Update Properties of an existing Certificate")
* [Delete a Certificate](#delete-a-certificate "Delete a Certificate")
* [List Properites of Certificates](#list-properties-of-certificates "List Properties of Certificates")
* [Asynchronously create a Certificate](#asynchronously-create-a-certificate "Asynchronously create a Certificate")
* [Asynchronously list properties of Certificates](#asynchronously-list-properties-of-certificates "Asynchronously list properties of Certificates")

### Create a Certificate
[begin_create_certificate](https://aka.ms/azsdk-python-keyvault-certificates-begincreatecert-ref) creates a certificate to be stored in the Azure Key Vault.
If a certificate with the same name already exists, then a new version of the certificate is created.
Before creating a certificate, a management policy for the certificate can be created or our default
policy will be used. The [begin_create_certificate](https://aka.ms/azsdk-python-keyvault-certificates-begincreatecert-ref) operation returns a long running operation poller.
```python
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient, CertificatePolicy

credential = DefaultAzureCredential()

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

create_certificate_poller = certificate_client.begin_create_certificate(
    certificate_name="cert-name", policy=CertificatePolicy.get_default()
)
print(create_certificate_poller.result())
```
If you would like to check the status of your certificate creation, you can call `status()` on the poller or
[get_certificate_operation](https://aka.ms/azsdk-python-keyvault-certificates-getcertop-ref) with the name of the certificate.

### Retrieve a Certificate
[get_certificate](https://aka.ms/azsdk-python-keyvault-certificates-getcert-ref) retrieves a certificate previously stored in the Key Vault without
having to specify version.
```python
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient

credential = DefaultAzureCredential()

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

certificate = certificate_client.get_certificate("cert-name")

print(certificate.name)
print(certificate.properties.version)
print(certificate.policy.issuer_name)
```

[get_certificate_version](https://aka.ms/azsdk-python-keyvault-certificates-getcertversion-ref) retrieves a certificate based on the certificate name and the version of the certificate.
Version is required.
```python
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient

credential = DefaultAzureCredential()

certificate_client = CertificateClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential)
certificate = certificate_client.get_certificate_version(certificate_name="cert-name", version="cert-version")

print(certificate.name)
print(certificate.properties.version)
```

### Update properties of an existing Certificate
[update_certificate_properties](https://aka.ms/azsdk-python-keyvault-certificates-updatecertprops-ref) updates a certificate previously stored in the Key Vault.
```python
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient

credential = DefaultAzureCredential()

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

# we will now disable the certificate for further use
updated_certificate= certificate_client.update_certificate_properties(
    certificate_name="cert-name", enabled=False
)

print(updated_certificate.name)
print(updated_certificate.properties.enabled)
```

### Delete a Certificate
[begin_delete_certificate](https://aka.ms/azsdk-python-keyvault-certs-deletecert-ref) requests Key Vault delete a certificate, returning a poller which allows you to
wait for the deletion to finish. Waiting is helpful when the vault has [soft-delete][soft_delete]
enabled, and you want to purge (permanently delete) the certificate as soon as possible.
When [soft-delete][soft_delete] is disabled, [begin_delete_certificate](https://aka.ms/azsdk-python-keyvault-certs-deletecert-ref) itself is permanent.

```python
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient

credential = DefaultAzureCredential()

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

deleted_certificate = certificate_client.begin_delete_certificate("cert-name")

print(deleted_certificate.name)
print(deleted_certificate.deleted_on)
```
### List properties of Certificates
[list_properties_of_certificates](https://aka.ms/azsdk-python-keyvault-certs-listcerts-ref) lists the properties of all certificates in the specified Key Vault.
```python
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient

credential = DefaultAzureCredential()

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

certificates = certificate_client.list_properties_of_certificates()

for certificate in certificates:
    # this list doesn't include versions of the certificates
    print(certificate.name)
```

### Async operations
This library includes a complete async API supported on Python 3.5+. To use it, you must
first install an async transport, such as [aiohttp](https://pypi.org/project/aiohttp/).
See
[azure-core documentation](https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/core/azure-core/README.md#transport)
for more information.

### Asynchronously create a Certificate
[create_certificate](https://aka.ms/azsdk-python-keyvault-certs-async-createcert) creates a certificate to be stored in the Azure Key Vault. If a certificate with the
same name already exists, then a new version of the certificate is created.
Before creating a certificate, a management policy for the certificate can be created or our default policy
will be used. Awaiting the call to [create_certificate](https://aka.ms/azsdk-python-keyvault-certs-async-createcert) returns your created certificate if creation is successful,
and a [CertificateOperation](https://aka.ms/azsdk-python-keyvault-certs-models-certop-ref) if creation is not.
```python
from azure.identity.aio import DefaultAzureCredential
from azure.keyvault.certificates.aio import CertificateClient
from azure.keyvault.certificates import CertificatePolicy

credential = DefaultAzureCredential()

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

create_certificate_result = await certificate_client.create_certificate(
    certificate_name="cert-name", policy=CertificatePolicy.get_default()
)
print(create_certificate_result)
```

### Asynchronously list properties of Certificates
[list_properties_of_certificates](https://aka.ms/azsdk-python-keyvault-certs-async-listcerts-ref) lists all the
properties of the certificates in the client's vault:
```python
from azure.identity.aio import DefaultAzureCredential
from azure.keyvault.certificates.aio import CertificateClient

credential = DefaultAzureCredential()

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

certificates = certificate_client.list_properties_of_certificates()
async for certificate in certificates:
    print(certificate.name)
```

## Troubleshooting
### General
Key Vault clients raise exceptions defined in [azure-core][azure_core_exceptions].
For example, if you try to get a key that doesn't exist in the vault, [CertificateClient][certificate_client_docs]
raises [ResourceNotFoundError](https://aka.ms/azsdk-python-core-exceptions-resource-not-found-error):
```python
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient
from azure.core.exceptions import ResourceNotFoundError

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

try:
    certificate_client.get_certificate("which-does-not-exist")
except ResourceNotFoundError as e:
    print(e.message)
```
### Logging
This library uses the standard
[logging](https://docs.python.org/3.5/library/logging.html) 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:
```py
from azure.identity import DefaultAzureCredential
from azure.keyvault.certificates import CertificateClient
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 = CertificateClient(vault_url="https://my-key-vault.vault.azure.net/", credential=credential, logging_enable=True)
```

Network trace logging can also be enabled for any single operation:
 ```python
certificate = certificate_client.get_certificate(certificate_name="cert-name", logging_enable=True)
```

## Next steps
Several samples are available in the Azure SDK for Python GitHub repository. These samples provide example code for additional Key Vault scenarios:
* [test_examples_certificates.py][test_example_certificates] and
[test_examples_certificates_async.py][test_example_certificates_async] - code snippets from
the library's documentation
* [hello_world.py][hello_world_sample] and [hello_world_async.py][hello_world_async_sample] - create/get/update/delete certificates
* [backup_restore_operations.py][backup_operations_sample] and [backup_restore_operations_async.py][backup_operations_async_sample] - backup and
recover certificates

### 4.0.0b3 (2019-09-11)
Version 4.0.0b3 is the first preview of our efforts to create a user-friendly and Pythonic client library for Azure Key Vault's certificates.

 This library is not a direct replacement for `azure-keyvault`. Applications
using that library would require code changes to use `azure-keyvault-certificates`.
This package's
[documentation](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/keyvault/azure-keyvault-certificates/README.md)
and
[samples](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/keyvault/azure-keyvault-certificates/samples)
demonstrate the new API.

### Breaking changes from `azure-keyvault`:
- Packages scoped by functionality
    - `azure-keyvault-certificates` contains a client for certificate operations
- Client instances are scoped to vaults (an instance interacts with one vault
only)
- Authentication using `azure-identity` credentials
  - see this package's
  [documentation](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/keyvault/azure-keyvault-keys/README.md)
  , and the
  [Azure Identity documentation](https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/identity/azure-identity/README.md)
  for more information

### New Features:
- Distributed tracing framework OpenCensus is now supported
- Asynchronous API supported on Python 3.5.3+
    - the `azure.keyvault.certificates.aio` namespace contains an async equivalent of
    the synchronous client in `azure.keyvault.certificates`
    - Async clients use [aiohttp](https://pypi.org/project/aiohttp/) for transport
    by default. See [azure-core documentation](https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/core/azure-core/README.md/#transport)
    for more information about using other transports.
