        You must specify the ``cookie_secret`` setting in your Application
        to use this method. It should be a long, random sequence of bytes
        to be used as the HMAC secret for the signature.

        To read a cookie set with this method, use `get_secure_cookie()`.

        Note that the ``expires_days`` parameter sets the lifetime of the
        cookie in the browser, but is independent of the ``max_age_days``
        parameter to `get_secure_cookie`.

        Secure cookies may contain arbitrary byte values, not just unicode
        strings (unlike regular cookies)

           Added the ``version`` argument.  Introduced cookie version 2
           and made it the default.
