What does the "Certificates" / "System Trust" section of seahorse do?
I am trying to sign a document in LibreOffice and the menu there uses the word "Certificate", so I am thinking that I need to have something here. I already have my GPG key imported into the "PGP Keys" -> "GnuPG keys" menu and its trust is set to ultimate.
Is there a way I can make the system trust the key or make the key into a certificate so that I can use it to sign my document? Or is this part of the menu for something completely different (if so, how do I get LibreOffice to use my GPG key?).
