Namespace: PdfSharp.Pdf.Security
Abstract class declaring the common methods of crypt filters. These may be the IdentityCryptFilter or PdfCryptFilters defined in the CF dictionary of the security handler.

Gets the dictionary containing the elements of this dictionary.
public DictionaryElements Elements { get; }
Gets or sets the PDF stream belonging to this dictionary. Returns null if the dictionary has no stream. To create the stream, call the CreateStream function.
public PdfStream Stream { get; set; }
Gets the PdfDocument this object belongs to.
public PdfDocument Owner { get; }
Indicates whether the object is an indirect object.
public bool IsIndirect { get; }
Gets the PdfInternals object of this document, that grants access to some internal structures which are not part of the public interface of PdfDocument.
public PdfObjectInternals Internals { get; }
Gets the indirect reference of this object. If the value is null, this object is a direct object.
public PdfReference Reference { get; internal set; }
Gets the indirect reference of this object. Throws if it is null.
public PdfReference ReferenceNotNull { get; }
InvalidOperationException
The indirect reference must be not null here.
Encrypts the given bytes. Returns true if the crypt filter encrypted the bytes, or false, if the security handler shall do it.
