318 * Functions used to protect against Cross-Site Request Forgery
319 * The security token has to base on at least one value that an attacker can't know - here it's the session ID and the private key.
320 * In this implementation, a security token is reusable (if the user submits a form, goes back and resubmits the form, maybe with small changes;
321 * or if the security token is used for ajax-calls that happen several times), but only valid for a certain amout of time (3hours).
322 * The "typename" seperates the security tokens of different types of forms. This could be relevant in the following case:
323 * A security token is used to protekt a link from CSRF (e.g. the "delete this profile"-link).
324 * If the new page contains by any chance external elements, then the used security token is exposed by the referrer.
325 * Actually, important actions should not be triggered by Links / GET-Requests at all, but somethimes they still are,
326 * so this mechanism brings in some damage control (the attacker would be able to forge a request to a form of this type, but not to forms of other types).
