Version 4.0.0b3 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-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.

- 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

- 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.
