If the key is based on hardware details that only root can obtain, it would
require at least having the time to boot the victim computer into another OS
to create the key. If the key is also dependant on details of the running
kernel, it could be even harder to crack it.
Password-based encryption might be wanted for certain cases, but I think most
cases would do fine to prevent the image from being used for anything except
restoring on the original system. That way, it would be significantly more
difficult for someone to gain access to the memory that could be used for
other encrypted things (such as GPG key generation).
