    An object to sign requests before they go out over the wire using
    one of the authentication mechanisms defined in ``auth.py``. 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`

    First you create a cloudfront signer based on a normalized RSA signer::

        import rsa

            private_key = open('private_key.pem', 'r').read()
            return rsa.sign(

                'SHA-1')  # CloudFront requires SHA-1 hash
        cf_signer = CloudFrontSigner(key_id, rsa_signer)

    To sign with a canned policy::

        signed_url = cf_signer.generate_signed_url(
            url, date_less_than=datetime(2015, 12, 1))

    :type Bucket: string
    :param Bucket: The name of the bucket to presign the post to. Note that
        bucket related conditions should not be included in the
        ``conditions`` parameter.

    :type Key: string
    :param Key: Key name, optionally add ${filename} to the end to
        attach the submitted filename. Note that key related conditions and
        fields are filled out for you and should not be included in the
        ``Fields`` or ``Conditions`` parameter.

    :type Fields: dict
    :param Fields: A dictionary of prefilled form fields to build on top
        of. Elements that may be included are acl, Cache-Control,
        Content-Type, Content-Disposition, Content-Encoding, Expires,
        success_action_redirect, redirect, success_action_status,
        and x-amz-meta-.

        Note that if a particular element is included in the fields
        dictionary it will not be automatically added to the conditions
        list. You must specify a condition for the element as well.

    :type Conditions: list
    :param Conditions: A list of conditions to include in the policy. Each
        element can be either a list or a structure. For example:

        [
         {"acl": "public-read"},
         ["content-length-range", 2, 5],
         ["starts-with", "$success_action_redirect", ""]
        ]

        Conditions that are included may pertain to acl,
        content-length-range, Cache-Control, Content-Type,
        Content-Disposition, Content-Encoding, Expires,
        success_action_redirect, redirect, success_action_status,
        and/or x-amz-meta-.

        Note that if you include a condition, you must specify
        the a valid value in the fields dictionary as well. A value will
        not be added automatically to the fields dictionary based on the
        conditions.

    :type ExpiresIn: int
    :param ExpiresIn: The number of seconds the presigned post
        is valid for.

    :rtype: dict
    :returns: A dictionary with two elements: ``url`` and ``fields``.
        Url is the url to post to. Fields is a dictionary filled with
        the form fields and respective values to use when submitting the
        post. For example:

        {'url': 'https://mybucket.s3.amazonaws.com
