Hello Natale, first of all, thank you very much for your quick reply. Perhaps I did not explain the problem well enough. I did not modify a digitally signed pdf. In short, the problem is any writer document containing at least one text box cannot be properly exported to pdf with a digital signature.
The easiest way to reproduce (with the mentioned Version/Build on debian 10) is as follows. 1) Open libreoffice writer 2) Insert a text box into the blank sheet containing the text "This is a text box" 3) Export the document to pdf with digital signature 4) Open the pdf with libreoffice draw => Look at libreoffice draw's notice about the signature Greetings, -----Original Message----- From: Natale Tarantino <[email protected]> To: [email protected] Cc: [email protected] Subject: Re: [libreoffice-users] Problems when digitally signing PDF exports of *.odt documents containing text boxes Date: Thu, 19 May 2022 18:39:56 +0200 If you modify a digitally signed pdf this is the correct behavior.
