After Leonard stated in this thread I experimented a bit, and indeed, it was possible to add LTV-DSS data to a signed document using iText methods for PDF manipulation, and Acrobat Reader used them. Admittedly, the iText methods to use are low-level, but the public iText API sufficed. If you are content with using the iText methods for external signature container and signature dictionary creation, I'm inclined to think even PAdES BES and EPES signatures and document timestamps can be applied to a PDF document using merely the public iText API for PDF manipulation. Otherwise I'm with Leonard when he states Leonard Rosenthol-3 wrote: > Yes, you would need to modify the source code.
