Writing documentation about a software project that is very alive and to which new functionality is added frequently, is a work that is constantly under construction. You can reward the work that is done on the documentation by buying the book about iText.

From iText version 2.0.3 and iTextSharp 4.0.4 the password restrictions are enforced by the library instead of passing that responsability to the developer. Using PdfStamper or importing pages in PdfStamper, PdfCopy and PdfWriter will throw an exception if the PDF was not opened with the owner password.
