/** <p><em><b>Veraltete</b></em> Passport-Klasse f�r RDH-Zug�nge mit Sicherheitsmedium "Datei".
Diese Klasse sollte nicht mehr benutzt werden, sondern statt dessen die Klasse

RDH-Passport-Datei k�nnen mit dem Tool
{@link org.kapott.hbci.tools.ConvertRDHPassport} oder
mit Hilfe des separat verf�gbaren <em>HBCI4Java Passport Editors</em>
in RDHNew-Passport-Dateien umgewandelt werden. Siehe dazu auch die Daten
