Hi, thanks a lot, calling
reader.getAcroForm().remove(PdfName.SIGFLAGS) in addition to removing the signature field indeed solves my problem!

Also remove the sigflags in acroform. You can remove all in the reader and just use the stamper to output the result.

Hi, using stamper.getAcroFields() still isn't enough to completely remove the signature. I still cannot apply password encryption to the resulting pdf file in acrobat pro v8 ("the security policy cannot be changed because the document is signed or certified"). Any other ideas?

You should get it from the stamper: AcroFields acroFields = stamper.getAcroFields(); But I don't know if this will be sufficient to remove the signature. -- This answer is provided by 1T3XT BVBA http://www.1t3xt.com/ - http://www.1t3xt.info ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php This e-mail and any attachment thereto may contain confidential information and/or information protected by intellectual property rights for the exclusive attention of the intended addressees named above.
