NAS feature seems to work ok with ntfs, exfat and ext4. Openwrt includes packages for cryptsetup, so luks encryption should be possible with ext4. Perhaps veracrypt works also ok. I not sure whether it is (easily) possible to use bitlocker (cryptsetup or dislocker) in openwrt.
I think it would be nice to include a tab in the Network Storage option for disk encryption, password based perhaps is enough.
Not sure if this is a desired feature, so I open a poll.
- Yes, luks or any other option
- No, not needed
