Bug ID: 143134
Summary: PDF restrictions in signed PDF documents
Product: LibreOffice
Version: 7.1.0.1 rc
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Printing and PDF export
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: renato...@gmail.com
Description:
This is an inquire about digital signatures on PDF files.
First, I would like to congratulate about the well done job which delivers
digital signature to PDF at LibreOffice. The process has been implemented by a
very good functionality; however, The departament of my city is not accepting
the signed PDF once they intend to add notes and new signatures to the same
PDF. Retrieving permissions of the signed PDF in another PDF reader, I realized
that new comments and signatures are not allowed in their software. Some
permissions that had been allowed before the signature process became
restricted after the signature at LibreOffice. I also realized that their
software are opening PDF in read-only status.
To sum up, the signed PDF generated have been flagged with no comments, no new
signatures and no editable permissions. Therefore, I would request you to
provide new flags available through checkbox selection in PDF exportation or
PDG signing process.
PS.: a ICP Brasil token was used in the process.

PDF signing at LibreOffice.
Reproducible: Always
User Profile Reset: No
Additional Info:
