awssig 0.2.2

AWS signature verification routines

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 on pythonhosted.

Currently only SigV4 is 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": (

...             "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)
