ItextSharp - Merging pdf files disables extended reader permissions?

Reader permissions can be enabled only by Adobe products. They are based on a custom digital signature that is invalidated when the file is modified. The certificate for this digital signature is owned by Adobe and it is not public, also the computation of this digital signature is not documented.

You cannot re-enable in any way the reader permissions after you merged the files, unless you use Acrobat on the merged file.

In order to preserve existing reader enabled permissions, you have to use a PdfStamper in APPEND mode.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
