Hello all, I've been using iText for a while, and now I need to implement a 2-step signing process which is similar to signing using a smart card. The book iText in Action (second edition) mentions that there is a way to avoid keeping the PdfStamper open throughout the signing process (note at the end of section 12.4.5), but I couldn't figure out how to do such a thing.
I've tried creating the following process: 1. Do the normal signing stuff, up to the point where the hash of the contents to be signed is generated (right after the preClose); 2. Sign the hash (using BC); 3. Repeat the first step (open pdf, do stuffs, preClose); 4. Insert signed hash from step 2 (which is the hash from step 1). But this didn't work out. Adobe Reader says the document was changed. Is this approach wrong? How could I accomplish this?
