Property Value

This is used when creating encrypted PDF documents. PDF documents can be encrypted at two levels: low (40-bit RC4) and high (128-bit RC4). To change the encryption level, use the EncryptionMode property.

PDF documents can be protected (secured) in two different ways, as follows:

• Protected against viewing. PDF viewer applications will request a password from the user when the document is opened for viewing. This password is called the user password. To protect a PDF document against viewing, set the Protected property to true and the UserPassword property to the password value.

• Protected against editing. PDF editor applications will request a password from the user when the document is opened for editing. This password is called the owner password. To protect a PDF document against editing, set the Protected property to true and the OwnerPassword property to the password value.

When a PDF document is protected against editing (through the use of an owner password), an encryption level and owner access rights can be granted or denied in the resulting document. The following table lists the PDF access rights supported by the LEADTOOLS Document Writers:

Note that Owner Access Rights (UserPassword and OwnerPassword) have effect only if you set the Protected property to true.

Note that Protected is not supported when the DocumentType is PdfDocumentType.PdfA.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
