WebService::AWS::Auth::V4

A library for AWS Auth V4 methods.

DESCRIPTION

AWS employs a set of signing processes in order to create authorized requests. This library provides an implementation of the v4 signing requirements as described here:

http://docs.aws.amazon.com/general/latest/gr/signature-version-4.html

This library conforms to a set of published conformance tests that AWS publishes here:

http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html

This library passes these tests. This is not a general purpose library for using AWS services, although v4 signing is a requirement for any toolkit that provides an AWS API, so this library may be useful as a foundation for an AWS API.
