All the content, links, outlines, etc, are kept. It is also possible to change the info dictionary. Method Summary public static  void encrypt(PdfReader reader, OutputStream os, byte userPassword, byte ownerPassword, int permissions, boolean strength128Bits)      Entry point to encrypt a PDF document. public static  void encrypt(PdfReader reader, OutputStream os, byte userPassword, byte ownerPassword, int permissions, boolean strength128Bits, HashMap newInfo)      Entry point to encrypt a PDF document. public static  void encrypt(PdfReader reader, OutputStream os, boolean strength, String userPassword, String ownerPassword, int permissions)      Entry point to encrypt a PDF document. public static  void encrypt(PdfReader reader, OutputStream os, boolean strength, String userPassword, String ownerPassword, int permissions, HashMap newInfo)      Entry point to encrypt a PDF document. public static  void encrypt(PdfReader reader, OutputStream os, int type, String userPassword, String ownerPassword, int permissions, HashMap newInfo)      Entry point to encrypt a PDF document. public static  void encrypt(PdfReader reader, OutputStream os, int type, String userPassword, String ownerPassword, int permissions)      Entry point to encrypt a PDF document. public static  String getPermissionsVerbose(int permissions)      Give you a verbose analysis of the permissions. Method Detail encrypt public static void encrypt(PdfReader reader, OutputStream os, byte userPassword, byte ownerPassword, int permissions, boolean strength128Bits) throws DocumentException, IOException(Code) Entry point to encrypt a PDF document. The encryption parameters are the same as in PdfWriter. The userPassword and the ownerPassword can be null or have zero length. In this case the ownerPassword is replaced by a random string. The open permissions for the document can be AllowPrinting, AllowModifyContents, AllowCopy, AllowModifyAnnotations, AllowFillIn, AllowScreenReaders, AllowAssembly and AllowDegradedPrinting. The permissions can be combined by ORing them. Parameters:   reader - the read PDF Parameters:   os - the output destination Parameters:   userPassword - the user password. Can be null or empty Parameters:   ownerPassword - the owner password. Can be null or empty Parameters:   permissions - the user permissions Parameters:   strength128Bits - true for 128 bit key length, false for 40 bit key length throws:   DocumentException - on error throws:   IOException - on error encrypt public static void encrypt(PdfReader reader, OutputStream os, byte userPassword, byte ownerPassword, int permissions, boolean strength128Bits, HashMap newInfo) throws DocumentException, IOException(Code) Entry point to encrypt a PDF document.
