Darabonba Signature Utility

The `alibabacloud-darabonba-signature-util` library, version 0.0.4, is a low-level utility component of the Alibaba Cloud Python SDK ecosystem. It provides essential cryptographic functions for signing requests, including HMAC-SHA1 and HMAC-SHA256, and base64 encoding, based on the Darabonba framework. It's primarily designed for internal use by other Alibaba Cloud SDK modules rather than direct end-user application. The library currently has an infrequent release cadence, with the last significant update being over a year ago.
