I was wondering how I can store my keyfiles for my HDDs securely.
The situation:
I have 4 HDDs all of them are encrypted and I really don't want to type in each password for each drive, every time I start my machine.
I haven't added all of them into one LVM-Container, so I have to open each drive separately.
Anyway I was thinking about the following scenario:
I would create keyfiles for each drive and then put the keyfiles into one encrypted tar-archive or maybe something more handy.
And to make sure these files aren't stored in a permanent way I would mount an tmpfs and extract the archive only on that mountpoint/directory, so they are gone, when I umount the tmpfs.
What do you guys think? Would you consider this secure?
Do you have a more handy idea for archving the keyfiles?
Thanks for all advises
