Hi.
I've been using iText to sign PDF files. I've learned how to do that with
the help of the examples in http://itextpdf.sourceforge.net/howtosign.html.

My problem is: I need the signature to be calculated from the bytes of the
original file only. When using the examples in the site above, the signature
is calculated from the original file plus the bytes of the signature
dictionary. I don't want to include the signature dictionary in the
calculation of the digest and signature. So, what I need is a way to set the
ByteRange field to the number bytes in the original file.

Any ideas on how to do this? Is it possible? From what I've read in the PDF
Reference, I think it is. I just need some help on how to do it using iText.

Thanks in advance.
