+# Azure Key Vault Certificates client library for Python
+Azure Key Vault is a cloud service that provides a secure management of certificates, which are built on top of keys and secrets and adds an automated renewal feature. The certificate client library allows you securely store and manage the life-cycle of your certificate, be notified about certificate life-cycle events, and supports automatic renewal with selected issuers. This library offers operations to create, retrieve, update, delete, purge, backup, restore, and list the certificates and its versions, and offers CRUD operations for the certificate issuers, contacts, and management policies of the certificates..
+
+[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 the Azure Key Vault client library for Python with [pip][pip]:
+
+```Bash
+pip install azure-keyvault-certificates
+```
+
+### Prerequisites
+* An [Azure subscription][azure_sub].
+* Python 2.7, 3.5.3, or later to use this package.
+* An existing Key Vault. If you need to create a Key Vault, you can use the [Azure Cloud Shell][azure_cloud_shell] to create one with this Azure CLI command. Replace `<your-resource-group-name>` and `<your-key-vault-name>` with your own unique names:
+
+    ```Bash
+    az keyvault create --resource-group <your-resource-group-name> --name <your-key-vault-name>
+    ```
+
+### Authenticate the client
+In order to interact with the Key Vault service, you'll need to create an instance of the [CertificateClient][certificate_client_docs] class. You would need a **vault url** and **client certificate credentials (client id, client secret, tenant id)** to instantiate a client object for using the `DefaultAzureCredential` examples in the README. `DefaultAzureCredential` authentication is achieved by providing client certificate credentials as seen in this getting started section, but you can find more ways to authenticate with [azure-identity][azure_identity].
+
+ #### Create/Get credentials
+Use the [Azure Cloud Shell][azure_cloud_shell] snippet below to create/get client certificate credentials.
+
+ * Create a service principal and configure its access to Azure resources:
+    ```Bash
+    az ad sp create-for-rbac -n <your-application-name> --skip-assignment
+    ```
+    Output:
+    ```json
+    {
+        "appId": "generated-app-ID",
+        "displayName": "dummy-app-name",
+        "name": "http://dummy-app-name",
+        "password": "random-password",
+        "tenant": "tenant-ID"
+    }
+    ```
+* Use the credentials returned above to set **AZURE_CLIENT_ID**(appId), **AZURE_CLIENT_SECRET**(password) and (password) and **AZURE_TENANT_ID**(tenant) 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"
+  ```
+
+* Grant the above mentioned application authorization to perform certificate operations on the keyvault:
+    ```Bash 
+    az keyvault set-policy --name <your-key-vault-name> --spn $AZURE_CLIENT_ID --certificate-permissions backup create delete get import list purge recover restore update
+    ```
+    > --certificate-permissions:
+    > Accepted values: backup, create, delete, deleteissuers, get, getissuers, import, list, listissuers, managecontacts, manageissuers, purge, recover, restore, setissuers, update
+
+* Use the above mentioned Key Vault name to retrieve details of your Vault which also contains your Key Vault URL:
+    ```Bash
+    az keyvault show --name <your-key-vault-name>
+    ```
+
+#### Create Certificate client
+Once you've populated the **AZURE_CLIENT_ID**, **AZURE_CLIENT_SECRET** and **AZURE_TENANT_ID** environment variables and replaced **your-vault-url** with the above returned URI, you can create the [CertificateClient][certificate_client_docs]:
+
+```python
+    from azure.identity import DefaultAzureCredential
+    from azure.keyvault.certificates import CertificateClient
+
+    credential = DefaultAzureCredential()
+
+    # Create a new certificate client using the default credential
+    certificate_client = CertificateClient(vault_url=<your-vault-url>, credential=credential)
+```
+## Key concepts
+### Certificate
+  A certificate is the fundamental resource within Azure KeyVault. From a developer's perspective, Key Vault APIs accept and return certificates as the Certificate type. In addition to the certificate data, the following attributes may be specified:
+* expires: Identifies the expiration time on or after which the certificate data should not be retrieved.
+* not_before: Identifies the time after which the certificate will be active.
+* enabled: Specifies whether the certificate data can be retrieved.
+* created: Indicates when this version of the certificate was created.
+* updated: Indicates when this version of the certificate was updated.
+
+### Certificate Client:
+The Certificate client performs the interactions with the Azure Key Vault service for getting, setting, updating, deleting, and listing certificates and their versions. An asynchronous and synchronous CertificateClient exists in the SDK allowing for selection of a client based on an application's use case. Once you've initialized a CertificateClient, you can interact with the primary resource types in Key Vault.
+
+## Examples
+The following section provides several code snippets using the above created `certificate_client`, covering some of the most common Azure Key Vault Certificate service related tasks, including:
+* [Create a Certificate](#create-a-certificate)
+* [Retrieve a Certificate](#retrieve-a-certificate)
+* [Update an existing Certificate](#update-an-existing-certificate)
+* [Delete a Certificate](#delete-a-certificate)
+* [List Certificates](#list-certificates)
+* 
+
+### Create a Certificate
+`create_certificate` 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 `create_certificate` operation returns a long running operation poller in both the synchronous and asynchronous method.
+```python
+    create_certificate_poller = certificate_client.create_certificate(name="cert-name")
+
+    create_certificate_poller.wait()
+    print(create_certificate_poller.result())
+```
+
+### Retrieve a Certificate
+`get_certificate_with_policy` retrieves a certificate previously stored in the Key Vault without having to specify version.
+```python
+    certificate = certificate_client.get_certificate_with_policy(name="cert-name")
+
+    print(certificate.name)
+    print(certificate.version)
+```
+
+### Update an existing Certificate
+`update_certificate` updates a certificate previously stored in the Key Vault.
+```python
+    # You can specify additional application-specific metadata in the form of tags.
+    tags = {"foo": "updated tag"}
+
+    updated_certificate= certificate_client.update_certificate(name="cert-name", tags=tags)
+
+    print(updated_certificate.name)
+    print(updated_certificate.version)
+    print(updated_certificate.updated)
+    print(updated_certificate.tags)
+
+```
+
+### Delete a Certificate
+`delete_certificate` deletes a certificate previously stored in the Key Vault. When [soft-delete][soft_delete] is not enabled for the Key Vault, this operation permanently deletes the certificate.
+```python
+    deleted_certificate = certificate_client.delete_certificate(name="cert-name")
+
+    print(deleted_certificate.name)
+    print(deleted_certificate.deleted_date)
+```
+### List Certificates
+This example lists all the certificates in the specified Key Vault.
+```python
+    certificates = certificate_client.list_certificates()
+
+    for certificate in certificates:
+        # this list doesn't include versions of the certificates
+        print(certificate.name)
+```
+
+## Troubleshooting
+### General
+Key Vault clients raise exceptions defined in azure-core. For more detailed information about exceptions and how to deal with them, see [Azure Core exceptions][azure_core_exceptions].
+
+For example, if you try to retrieve a certificate after it is deleted a `404` error is returned, indicating resource not found. In the following snippet, the error is handled gracefully by catching the exception and displaying additional information about the error.
+```python
+from azure.core.exceptions import ResourceNotFoundError
+try:
+    certificate_client.get_certificate(name="deleted_certificate", version="deleted_certificate_version")
+except ResourceNotFoundError as e:
+    print(e.message)
+
+Output: "certificate not found:deleted_certificate"
+```
+### Logging
+Network trace logging is disabled by default for this library. When enabled, this will be logged at DEBUG level. The logging policy is used to output the HTTP network trace to the configured logger. You can configure logging to print out debugging information to the stdout or write it to a file using the following example:
+
+ ```python
+import sys
+import logging
+ # Create a logger for the 'azure' SDK
+logger = logging.getLogger(__name__)
+logger.setLevel(logging.DEBUG)
+ # Configure a console output
+handler = logging.StreamHandler(stream=sys.stdout)
+logger.addHandler(handler)
+ # Configure a file output
+file_handler = logging.FileHandler(filename)
+logger.addHandler(file_handler)
+
+# Enable network trace logging. This will be logged at DEBUG level.
+# By default, network trace logging is disabled.
+config = CertificateClient.create_config(credential=credential, logging_enable=True)
+client = CertificateClient(vault_url=url, credential=credential, config=config)
+```
+The logger can also be enabled per operation.
+
+ ```python
+certificate = certificate_client.get_certificate_with_policy(name="cert-name", logging_enable=True)
+```
+
