I am the root user of the VPS but the hosting company also has access to the VPS and thus all files. Is it possible to create a LUKS-container on the VPS and those files only be accessible by me? IOW, most of the file system on the VPS would be regular file system but the container could be used by me as needed. This would allow the VPS to reboot normally, I could ssh in normally etc etc. I would rsync files as needed to this LUKS-container though. >>> >>> _______________________________________________ >>> CentOS mailing list >>> CentOS at centos.org >>> https://lists.centos.org/mailman/listinfo/centos >> How about a loop way?

I googled it together with Linux and file and did not find anything. Is this simply like a separate file that is LUKS-encrypted and I would then mount it for remote access? If so, what would prevent the hosting company - which I presume is the root user - from also accessing it? That's that precisely, very easy. a) use dd to create a a file, eg.: dd if=/dev/zero of=gor.loop bs=1M count=2000 b) luks encrypt it: cryptsetup luksFormat gor.loop c) dev mapper mount it: cryptsetup luksOpen gor.loop luks-gor.loop d) fs it: mkfs.ext4 /dev/mapper/luks-gor.loop e) mount it: mount /dev/mapper/luks-gor.loop $PWD/gor.rootfs.encrypted f) use it (to simplify I'd put cryptOpen + mount + unmount + luksClose into a script) g) remember!! still at least (depending how you mount it) the 'root' will have access to that data while mounted, obviously! > _______________________________________________ > CentOS mailing list > CentOS at centos.org > https://lists.centos.org/mailman/listinfo/centos
