Digital signature in slackware?
 

I am trying to sign and certify an adobe file for this company that wants to hire. How can I do this in adobe and in general in slackware. Is there an adobe sign slackbuild for slackware? I guess this is more of a general question than a slackware one but since we are a separate distribution with its own package manager and style I wish to ask you guys, it MUST be a digital signature certificate. I downloaded adobe reader but can't seem to be able to access the certificate. So I guess naturally the next question would be can I use adobe reader to insert a Digital Signature Certificate and if not will adobe-sign work in slackware?

The title of your thread is so misleading that's worth of a scandal gazette!

What you make to think that Adobe's proprietary digital signing of PDF's is The Digital Signature Certificate which any "separate distribution" should sport?

Well can I use adobe reader to provide a Digital Signature Certificate in slackware and if not what can I use to digitally sign documents in slackware? If I can not do it in slakcware than just tell me.

I sign documents with PDF Studio Pro. It's commercial software, but there is a SlackBuild available (i.e., the maintainer rebundles the official binary for an easy upgrade/install on Slackware).

I thought it was possible to sign pdf's with Libreoffice. But I am not entirely sure.

In the menu File → Digital signatures → Sign existing PDF

edit: Nope, doesn't work.

The thread title seems fine (it could include the word PDF to be clearer, but whatever).

The OP wants a way to sign PDFs, preferably with software installed via Slackware's packaging system. I don't see the problem.

Master PDF Editor is an alternative. Buildscript at slackbuilds.org and you might prefer an older version (4.x), not version 5.x (see https://www.linuxuprising.com/2019/0...for-linux.html )
