Hi Randolph, have a look at the Doc from Adobe: 'PDF Public-Key Digital Signature and Encryption Specification' http://partners.adobe.com/asn/developer/pdfs/tn/ppk_pdfspec.pdf
There you can find information about how Byte-Ranges are calculated. The signature has to be calculated exactly over the bytes referenced in the ByteRange parameter. The best start is to produce a signed PDF with Acrobat full version (or download one from the Internet) and look at it with a text editor.
