Module: Simplepay::Authentication

Defined in:: lib/simplepay/authentication.rb

Overview

This module generates RFC-2104-compliant HMAC signatures. These signatures are used by both Amazon and you to determine whether or not data transmitted is authentic. The hash is based on the amazon secret access key, which is a trusted secret between both parties.

HMAC (RFC-2104 Specification)
