NAME
   Net::Amazon::Signature::V4 - Implements the Amazon Web Services
   signature version 4, AWS4-HMAC-SHA256

VERSION
   Version 0.19

SYNOPSIS
   This module signs an HTTP::Request to Amazon Web Services by appending
   an Authorization header. Amazon Web Services signature version 4,
   AWS4-HMAC-SHA256, is used.

       use Net::Amazon::Signature::V4;

       my $sig = Net::Amazon::Signature::V4->new( $access_key_id, $secret, $endpoint, $service );
       my $req = HTTP::Request->parse( $request_string );
       my $signed_req = $sig->sign( $req );
       ...

   The primary purpose of this module is to be used by
   Net::Amazon::Glacier.

METHODS
 new( $access_key_id, $secret, $endpoint, $service )
   Constructs the signature object, which is used to sign requests.

   Note that the access key ID is an alphanumeric string, not your account
   ID. The endpoint could be "eu-west-1", and the service could be
   "glacier".

 sign( $request )
   Signs a request with your credentials by appending the Authorization
   header. $request should be an HTTP::Request. The signed request is
   returned.
