# azure-storage-common — Microsoft Azure Storage Common Client Library for Python

License: permissive · Maintenance: dormant · Downloads: 11.3M/mo

## What it is and what it does

azure-storage-common is a shared foundation library for Microsoft Azure Storage client packages. It provides common code—authentication, request signing, retry logic, and utility functions—used by service-specific packages for blob, queue, and file storage. The package itself is not typically imported directly by end users; instead, it is a dependency of other Azure Storage packages.

The package depends on cryptography, requests, python-dateutil, and azure-common to handle secure communication, HTTP operations, date handling, and Azure SDK conventions. It supports Python 2.7, 3.3, 3.4, 3.5, 3.6, and 3.7 according to its classifiers. Because its last release was in August 2019 and no updates have been published since, it is considered dormant.

Use it for:

- Dependency resolution when installing azure-storage-blob, azure-storage-queue, or azure-storage-file packages that require shared common code.
- Legacy projects using pre-2019 Azure Storage SDK versions that cannot migrate to newer releases.
- Understanding or debugging authentication and request-signing logic in older Azure Storage client implementations.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides shared client library code for Microsoft Azure Storage services (blob, queue, file), handling authentication, common operations, and utilities used by service-specific packages.

No, not for new projects. This package is dormant (last release August 2019) and is a shared dependency of older Azure Storage SDK versions. For new work, install the service-specific packages you need directly—they will pull in azure-storage-common as a transitive dependency if required. If you are maintaining legacy code that explicitly depends on it, install it only as needed to satisfy those older packages.

## Install

pip install azure-storage-common
uv add azure-storage-common
poetry add azure-storage-common

## Installing azure-storage-common

Before you install: Low install friction with a pure-Python wheel. Maintenance is dormant: last release was 2019-08-02, though the repository remains active with a recent commit on 2024-08-09. This is a foundational package; check whether the service-specific packages you actually need have more recent updates.

License in practice: MIT License (permissive). You may use, modify, and distribute this package freely in commercial and private projects, with only the requirement to include the license notice.

Quickstart:

pip install azure-storage-common

from azure.storage.common import CloudStorageAccount

account = CloudStorageAccount(account_name='name', account_key='key')

Requires an Azure Storage account with valid credentials (account name and key or connection string). This is a shared library; you typically install service-specific packages instead of using it directly.

Verify before relying:

- Whether this package is still actively maintained or has been superseded by newer Azure SDK versions.
- Current compatibility with Python versions beyond 3.7, given the dormant maintenance status since 2019.
- Whether direct use of this package is recommended or if it should only be installed as a transitive dependency.
