Diese Beispiele sind bewusst einfach gehalten, zeigen aber, wie alles funktioniert.

In den Kapiteln zum Thema Sicherheit gibt es Hilfsfunktionen, die auf die gleiche Weise implementiert werden.

Wenn Sie das hier alles verstanden haben, wissen Sie bereits, wie diese Sicherheits-Hilfswerkzeuge unter der Haube funktionieren.
