Validates a dictionary containing Google service account data.

    Creates and returns a :class:`google.auth.crypt.Signer` instance from the
    private key specified in the data.

    Args:
        data (Mapping[str, str]): The service account data
        require (Sequence[str]): List of keys required to be present in the
            info.

    Returns:
        google.auth.crypt.Signer: A signer created from the private key in the
            service account file.

    Raises:
        ValueError: if the data was in the wrong format, or if one of the
            required keys is missing.
