Support mounting luks containers and devices

[vbenndorf]

Is your feature request related to a problem? Please describe.
I do not understand why cryfs and gocryptfs based encryption tools are treated so differently compared to other encryption systems (sorry, I'm not an expert. My terminology may be off). Not just in this app, but pretty much everywhere on the Linux desktop.

Describe the solution you'd like
I am hoping for Vaults to offer a way to import existing luks2 containers and disks (the stuff that uses cryptsetup on the terminal) pretty much the same way this can be done for cryfs and gocryptfs. The app should also be able to unlock, mount and open these devices.

Additional context
I understand that luks containers and disks are not suitable for cloud storage, but they are great for large media collections, and I'd like to have a central app I can use to mount all my encrypted filesystems (as a regular user without gaining privileges).

I am not a programmer and I have no idea how difficult this is, and, of course, I understand that we all face time constraints.

Hi! Vaults is intended to be a very simple and user friendly way to create and manage encrypted folders (e.g. for cloud or external storage). From a quick glance, it should be possible to add this backend, depending how much is available in the sandbox and what is available outside. It also depends on what you want to configure when adding/importing/opening such a container, so it's user-friendly as well. However, Vaults is somewhat in a maintenance mode since I no longer use it that frequently anymore, so features will be implemented at a slower pace.
