AWS-Signature4
==============

This is a Perl module for generating Version 4 signatures for use with
Amazon Web Services. It can be used to add authentication information
to the headers of GET, POST, PUT and DELETE.

The module can be also used to generate "signed" URLs. These are
preauthorized URLs that contain all the authentication and header
information in the URL query parameters. They can be sent to another
user to, for example, grant time-limited access to a private S3
bucket.

Relationship to Other Signature Modules
=======================================

This module has overlapping functionality with
Net::Amazon::Signature::V4, WebService::Amazon::Signature::v4, and
Net::Amazon::SignatureVersion4. None of these modules offers the
