Sign PDF with digital signature
Submitted by Hanno Meyer-Thurow

Since "support for digital signature" bug 16770 is included, how about adding support for actually signing PDF files?
For reference: LibreOffice 5.3 and newer supports signing PDF 1.5+ format. I wonder if it is possible to reuse their code wrt licensing? Just in case someone is interested, may talk to LibreOffice developers.
I mailed the LibreOffice developer, but got no response (yet).
