Thank you again Paulo.
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)?
