After some modification, I compiled pdftk to Dynamic link library Version, pdftk.dll, and wote a delphi example to show how to use this DLL, here is the delphi example,

program pas;

{$APPTYPE CONSOLE}

//uses
// SysUtils;
function Convert(argc : integer; argv : Array of string): Integer; stdcall; external 'pdftk.dll' name '_Z7ConvertiPPc@8';

var s: Array of string;
i,size:Integer;
begin
size :=System.ParamCount;

SetLength(s,size);
for i:=0 to size-1 do
s[i]:= ParamStr(i+1);
Convert(size,s);
end.

the point of this example is Convert function, and the usage of Convert function is as same as the main method of pdftk.cc, so we can easily implement some new methods, such as encrypt40, encrypt128, decrypt, compress, uncompress, flatten, cat(merge), attach_files, unpack_files, burst/split, fill_form Add_background, Add_stamp, generate_fdf, dump_data, dump_data_fields, update_info, and so on.
so the pdftk.dll has the following features,

Encrypt PDF with 48-bit and 128-bit support, of course, I can also implement AES support.
Decrypt PDF
Compress PDF
UnCompress PDF
Flatten PDF
Cat PDF/Merge PDF, AKA, PDF Cat/PDF Merge
Attach file to PDF
Extract attachment from PDF
Burst/Split PDF, AKA, PDF Split
Fill PDF Form
Add background to PDF
Add stamp to PDF
Generate FDF from PDF
Dump data
Dump data fields
Update PDF Info
Get PDF Info
Repair PDF
Rotate PDF

and if needed, I can also write a VB module to show how to use the pdftk.dll.
Any way, I still have no plan to release the pdftk.dll, because of some issues.
