[TYPO3-mvc] Implement own tt_address subscription (direct_mail)

[Jan Kornblum]

Hi all,

i would like to implement an own "tt_address" subscription for newsletters sent by "direct_mail". Similar to (old, not extbase) "direct_mail_subscription", users should be able to subscribe/confirm/unsubscribe/edit their subscription. Double-opt-in must be available.

As far as i know, something like an hash/authcode must be included into the requests (generated urls) to authorize any actions (unsubscribe/confirm). This authcode must be available inside "direct_mail" as well as inside the subscription module. So a "direct_mail" template contains this link pattern:

<f:link.page pageUid=123 additionalParams="{cmd: 'edit', aC: '###SYS_AUTHCODE###', rU: '###USER_uid###'}">
   Newsletter abbestellen | Empfängerdaten ändern
</f:link.page>

What about this "authcode"? How to generate it? Are there any core libraries? Can anybody point me into the right direction?

Kind regards, Jan
