DESCRIPTION

This module implements Amazon's Signature Version 4 as documented at http://docs.amazonwebservices.com/general/latest/gr/signature-version-4.html

The tests for this module are taken from the test suite provided by Amazon. This implementation does not yet pass all the tests. The following test is failing:

get-header-value-multiline: Amazon did not supply enough files for this test. The test may be run, but the results can not be validated.

METHODS

get_authorized_request

This method does most of the work for the user.  After setting the
request, region, service, access key, and secret access key, this
method will return a copy of the request headers with
authorization.

get_authorization

This method gets the authorization line that should be added to
the headers.  It is likely never to be used by the end user.  It
is here as a convenient test.

get_derived_signing_key

This method implements the derived signing key required for
version 4. It is likely never to be used by the end user.  It is
here as a convenient test.

get_string_to_sign

This method returns the string to sign.  It is likely never to be
used by the end user.  It is here as a convenient test.

get_canonical_request

This method returns the canonical request.  It is likely never to
be used by the end user.  It is here as a convenient test.
