Generate a new secret for a ticket with product ``item``, variation ``variation``, subevent ``subevent``,
attendee name ``attendee_name`` (can be ``None``) and the current secret ``current_secret`` (if any).
attendee name ``attendee_name`` (can be ``None``), earliest validity ``valid_from``, lastest validity
``valid_until``, and the current secret ``current_secret`` (if any).
The result must be a string that should only contain the characters ``A-Za-z0-9+/=``.
