Hi, we get signed PDF documents made with 3rd party software we need to add additional signature with iText. Problem is that the 1st signature gets invalid when 2nd is added. The error is: Error during signature verification. Unexpected byte range values defining scope of signed data. Details: The signature byte range is invalid We don't understand why this happens ? When we open the original document (with only 1st signature) no error is given so why is this invalidated with iText when new signature is added ? I attach the file with the 2 signatures (only 10 kb) so if someone can tell us what the problem is we might solve it. Any help much appreciated. ------------------------------------------------------------------------------ _______________________________________________ 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
