This class fires two events scoped to a service and operation name: * choose-signer: Allows overriding the auth signer name. * before-sign: Allows mutating the request before signing. Together these events allow for customization of the request signing pipeline, including overrides, request path manipulation, and disabling signing per operation. :type service_id: botocore.model.ServiceId :param service_id: The service id for the service, e.g. ``S3`` :type region_name: string :param region_name: Name of the service region, e.g. ``us-east-1`` :type signing_name: string :param signing_name: Service signing name. This is usually the same as the service name, but can differ. E.g. ``emr`` vs. ``elasticmapreduce``. :type signature_version: string :param signature_version: Signature name like ``v4``. :type credentials: :py:class:`~botocore.credentials.Credentials` :param credentials: User credentials with which to sign requests. :type event_emitter: :py:class:`~botocore.hooks.BaseEventHooks` :param event_emitter: Extension mechanism to fire events.
