Steven Lembark will walk us thru...
how to encrypt File systems in User SpacE (FUSE) for securing your private data. Both
LOCAL & REMOTE.
He’ll show us how to set it up, mount it, back it up, and recover it.
In the beginning was LUKS, and it was good... enough.
It encrypted a filesystem but it required privileged
access and knowlege of LVM and encryption standards.
(Linux Unified Key Setup (LUKS) is a disk encryption specification created in 2004. It
encrypts entire block devices and is therefore well-suited for protecting the contents of
mobile devices such as removable storage media.)
Then came FUSE (File systems in User SpacE ). This allows a non-privileged user to mount
filesystems using local code. The variety of
filesystems supported show just how useful the idea can be.
One early example encfs, which made it easy for non-
privileged users to access and encrypted filesystem.
Its an Encrypted FileSystem in user-space (EncFS). It runs stackably in userspace, using
the FUSE library for the filesystem interface. EncFS is open source.
Over time holes in its algorithm emerged and it became
un-maintained and is no longer secure. The good news
is, as every competent programmer knows, There's More
Than One Way To Do It. (At least 5!)
This talk looks at some alterntives to EncFS, their
foibles, and how to use them.
