I am working about a GUI PGP application with Zenity. GPG asks passphrase on terminal screen. But I want to enter passphrase from a GUI dialog box not in terminal (like
zenity --password) I tried piping
gpg -c <file_name> with Zenity command but not working. Is there any solution for this or another program feature? I know Kleopatra, GPA and seahorse by the way.
