awssig

This library provides signature verification for requests made to an AWS service. Typically, this is used to provide mock interfaces for AWS services or to rewrite AWS requests through a proxy host.

The current source tree can be found on GitHub.

Documentation is available at docs.ionosphere.io.

Currently only SigV4 and SigV4S3 (the S3 variant of SigV4) are supported.

Example Usage

>>> import awssig
>>> access_key = "AKIDEXAMPLE"
>>> secret_key = "wJalrXUtnFEMI/K7MDENG+bPxRfiCYEXAMPLEKEY"
>>> key_mapping = { access_key: secret_key }
>>> v = awssig.AWSSigV4Verifier(
...     request_method="GET",
...     uri_path="/",
...     query_string="a=foo&b=foo",
...     headers={
