NAME

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

VERSION

       Version 0.21

SYNOPSIS

           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 );
           ...

DESCRIPTION

       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.

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

METHODS

   new
           my $sig = Net::Amazon::Signature::V4->new( $access_key_id, $secret, $endpoint, $service );
           my $sig = Net::Amazon::Signature::V4->new({
               access_key_id => $access_key_id,
               secret        => $secret,
               endpoint      => $endpoint,
               service       => $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".

       Since version 0.20, parameters can be passed in a hashref. The keys "access_key_id",
       "secret", "endpoint", and "service" are required.  "security_token", if passed, will be
       applied to each signed request as the "X-Amz-Security-Token" header.

   sign
           my $signed_request = $sig->sign( $request );

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