The core module of Aliyun Python SDK.

No for new projects—use V2.0 SDK instead. Yes-with-conditions for legacy systems: only if you are maintaining existing V1.0 code and cannot migrate immediately. The package is stable and receives security patches, but the maintainers have made clear that V1.0 is deprecated and will not evolve. High install friction and lack of new features make it unsuitable for greenfield work.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires valid Alibaba Cloud Access Key ID and Access Key Secret obtained from the Alibaba Cloud console; product must be activated in the console before use.
- High install friction due to a single large tarball dependency.
- Package is actively maintained but explicitly deprecated—the maintainers recommend migrating to V2.0 SDK for new projects and existing deployments.

What it is and what it does
This is the core authentication and HTTP client library for Alibaba Cloud's V1.0 Python SDK. It handles credential management, request signing, and communication with Alibaba Cloud APIs, and is used as a base dependency by service-specific SDK packages. The package is no longer receiving new features and has entered basic security maintenance only.
The maintainers explicitly recommend that new projects use the V2.0 SDK instead, citing better performance, a more concise API, and more complete documentation. If you are already using V1.0, the official guidance is to migrate to V2.0 as soon as possible. Continuing to use V1.0 is viable for legacy systems but carries the risk of eventual end-of-life without major updates.
Use it for
- Maintain legacy Alibaba Cloud integrations written against the V1.0 SDK while planning migration to V2.0.
- Access Alibaba Cloud services in existing Python applications that cannot yet be refactored to V2.0.
- Authenticate and send API requests to Alibaba Cloud endpoints using HMAC-SHA1 signing and region-based routing.
- Debug cloud API calls using the built-in HTTP DEBUG feature by setting the DEBUG environment variable.
