I want to switch to Linux at work, and I am quite happy with the combo: Thunderbird ESR + Owl for Exchange and iCloud(!), Only Office for documents, Obsidan + Zotero for scientific notes.

I want to switch to Linux at work, and I am quite happy with the combo: Thunderbird ESR + Owl for Exchange and iCloud(!), Only Office for documents, Obsidan + Zotero for scientific notes.
I am struggling, however, to sign digitally PDF documents. Is there a way to get it in Debian Linux 12? #AskFedi #Debian #Linux

@jakmarcin are you able to run simple docker containers inside the VM? checkout bentopdf or stirlingpdf

@jakmarcin Foxit was great for me, when I was strictly Debian.

[jakmarcin@mstdn.science]

@numodular Will it allow me to sign the documents?

sudo apt install poppler-utils libnss3-tools

[1][2]

Poppler-utils has pdfsig: verify/add signatures; + pdftotext, pdfseparate, pdftops, pdfunite, ...

Libnss3-tools has certutil, signtool, ...

There's a PL gov web service for "trusted" signatures, though it violates the GDPR (publishes the signee's PESEL number in the signed pdf) [3][4] (update @UODO ?)
