B4J Question Protect editing of a PDF

[cardo]

Hello everyone.
I use PDFBox (version 0.27) with B4J to create a PDF and I would like to protect it against modification when saving the document.
Thank you for your help or for another lead

From what I know, it is possible to download edit protection from almost any PDF.
