>
> The random number generated is used as a secret to append to a sequence and
> SHA to implement a CookieSigner. If this is attackable, then it's possible
> for an attacker to sign a cookie as if we had. We should fix this and use
> SecureRandom as a stronger random function .
> HTTPAuthUtils has a similar issue. If that is attackable, an attacker might
> be able to create a similar cookie. Paired with the above issue with the
> CookieSigner, it could reasonably spoof a HS2 cookie.
