kolAflash <kolafl...@kolahilft.de> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #1 from kolAflash <kolafl...@kolahilft.de> --- Unfortunately the PDF standard doesn't allow OpenPGP signatures. You can only sign PDF files with X.509 certificates. There's a ticket to add a UI hint that only X.509 keys will work. bug 115884: PDF signing should mention it only works with x509 certificates As a workaround you can use KDE-Kleopatra (or directly GPG) to create a signature for the PDF as a separate SIG file. For that open KDE-Kleopatra and choose File->Sign/Encrypt. For further help ask at KDE or GPG. -- You are receiving this mail because: You are the assignee for the bug.
