+- The Split GPG client will fail to sign or encrypt if the private key in the
+GnuPG backend is protected by a passphrase, it will give a *"Inappropriate ioctl

+backend domain, it won't provide extra security anyway, as explained before. If
+you have a private key that already has a passphrase set use `gpg2 --edit-key
