Yes it's true, I need to realize a deferred signature. So I tried to "adapt" iText to my needs and I modified the src code. The differences between two consecutive hash computations are caused by: - the file ID (md5 of date, free space and a sequence) - the ModDate that it's impossible to eliminate also using this code (while it's possible for CreationDate): HashMap<String, String> info = (HashMap<String, String>)pdfReader.getInfo(); info.put("ModDate", null); Now that I have reached my goal, I'd like gently to know which are the problems that these changes can cause? Obviously I won't be aligned with future versions of iText but will my pdf files be valid and will they respect the Adobe standards (Acrobat doesn't find anything wrong)? 10x -- View this message in context: http://www.nabble.com/Hash-computation-problem-tp22801988p22842675.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------------ _______________________________________________ iText-questions mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php ------------------------------------------------------------------------------ _______________________________________________ iText-questions mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php
