PDF verschlüsseln

Verschlüsseln Sie ein PDF Dokument mit einem Benutzerpasswort und einem Eigentümerpasswort. Beim Öffnen des Dokuments muss eines der beiden Passwörter angegeben werden. Mit dem Benutzerpasswort kann das Dokument nur angesehen und gedruckt werden. Die Angabe des Eigentümerpassworts gewährt den vollen Zugriff auf das Dokument.

Signaturen im PDF auflisten

Erstelle eine Liste aller Signaturfelder und deren Eigenschaften aus einem PDF Dokument.

C# Beispiel:
// Open input document
