OK: advisory

# cat /etc/fstab | gpg --detach-sign > fstab.sig
# gpg --verify fstab.sig /etc/fstab
→ gpg: Korrekte Unterschrift von "Test Univention <test@univention.de>"

# test "$(sha256sum /etc/fstab | cut -f 1 -d ' ')" = "$(cat /etc/fstab | gpg --encrypt --recipient test@univention.de | gpg --decrypt - | sha256sum | cut -f 1 -d ' ')" && echo OK
