  var aws_params = {
    aws_endpoint : '',
    aws_secret_key : '',
    uri : '',
    verb : '',
    host : '',
    parameters : {
      signatureVersion : '',
      signatureMethod : '',
      accessKey : ''
    }
  };

and optional params from http://docs.aws.amazon.com/AmazonFPS/2010-08-28/FPSBasicGuide/GenericParameters.html

see test.js for an example https://github.com/theRemix/aws_signature_utils_js/blob/master/test.js
