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={
... "date": ["Mon, 09 Sep 2011 23:36:00 GMT"],
... "host": ["host.foo.com"],
... "authorization": [(
... "AWS4-HMAC-SHA256 "
... "Credential=AKIDEXAMPLE/20110909/us-east-1/host/aws4_request, "
... "SignedHeaders=date;host, "
... "Signature=0dc122f3b28b831ab48ba65cb47300de53fbe91b577fe113edac383730254a3b")],
... },
... body=b"",
... region="us-east-1",
... service="host",
... key_mapping=key_mapping,
... timestamp_mismatch=None)
>>> try:
... v.verify()
... print("ok")
... except awssig.InvalidSignatureError as e:
... print("error: %s" % e)
ok
>>> v = awssig.AWSSigV4S3Verifier(

... "x-amz-content-sha256": ["UNSIGNED-PAYLOAD"],
... },
... body=b"Hello world",
... region="us-east-1",
... service="host",
... key_mapping=key_mapping,
