org.apache.pdfbox.pdmodel.encryption.PDEncryption
This class is a specialized view of the encryption dictionary of a PDF document. It contains a low level dictionary (COSDictionary) and provides the methods to manage its fields. The available fields are the ones who are involved by standard security handler and public key security handler. @author Ben Litchfield @author Benoit Guillon
