[jira] [Commented] (PDFBOX-1837) PDDocument.save(String) doesn't correctly save digital signatures

    [ https://issues.apache.org/jira/browse/PDFBOX-1837?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13865291#comment-13865291 ] 

Álison Fernandes commented on PDFBOX-1837:
------------------------------------------

Thanks for your input on this Thomas!

In the context of my usage, all the changes were already made and I just need to digitally sign it, thus, the COSWriter problem doesn't affect me. That being said, if this is not to be supported, the final PDF shouldn't have any mention of a digital signature and it should be explicitly stated in the documentation (if it is, I'm sorry for the trouble but I missed it).

All in all, it would be great to have it supported nonetheless :)

> After digitally signing a PDF, if I save it with PDDocument.save(String), Adobe Reader reports the signature as invalid. The same doesn't happen if the PDF is saved with PDDocument.saveIncremental(FileInputStream, OutputStream).
