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


Version 0.16


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.


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.
