I want to create 200MB encrypted filesystem inside a regular file to keep it on my VDS, but be able to mount it locally: all decryption must be done by my local host.
This is my current sulution:
- Make random 200MB file:
dd if=/dev/zero bs=1M count=200 of=~/zzz
- Initialize it with LIKS:
cryptsetup luksFormat ~/zzz
- Open LUKS device:
sudo cryptsetup luksOpen ~/zzz sss
- Make filesystem on it:
sudo mkfs.ext4 /dev/mapper/sss
Now I can close LUKS device and:
- Put it to my VDS.
- Mount directory containint it on local folder using
sshfs
- Open LUKS device from that local folder
- Mount LUKS device to another folder
/mnt/sssand use this path to access to my data.
But this seems overcomplicated. I don't need SSH to encrypt my data: LUKS already did that and I can transmit parts of file zzz without any encryption. So I want some special network protocol that consider my remote file zzz as block device and transfer blocks of that device to my local PC. The ext4 will take care of network failures: connection lost will be considered by ext4 as ordinary power failure.
