Hi all, I've been reading this mailing list archives' for a week and i have two questions that i don't have so clear. I've been using itext for a long time but only for local signatures, so i'm stuck. I hope you can help me with these... #1.- I'm working in a project that has to sign a PDF with a external signature (PDF is in the server, certificate in the browser). I've no problem accesing the certificate, because this project in windows and jdk 6 based, so i can access it through "Windows-My". I´ve taken a look at the external signatures samples (http://itextpdf.sourceforge.net/howtosign.html) but i can't make my code work, because i don't have any private key to call mySignatureAppearance.setCrypto method... ¿how can i do this? I've also read that the hash is different each time, so you couldn't do this kind of signature without sending the PDF bytes to the client but im'not so sure ... is this really true? Is there anything smaller than the full PDF that i can send to the client to be signed? #2.- I know itext is not a PDF Parser (just read http://www.lowagie.com/iText/tutorial/ch13.html) and i know that there are several java based pdf parsers like PDFBox (http://www.pdfbox.org/) or JPedal (http://www.jpedal.org/) but i'd like to know if someone has used them successfully. All that i need is to read some data of a PDF that is always created the same way, so the data to read should be always located at the same place (al least, visually, i don't know if the PDF bytes would be similar). Thanks in advance, --
