So cryptsetup-reencrypt seems to be the recommended way. Therefore I recommend switching to cryptsetup-reencrypt, which is properly maintained and tested upstream even when the format of the LUKS header changes (to my knowledge, this has at least happened twice and can cause luksipc to catastrophically fail, i.e., destroy all your data in the worst case). Luksipc was created before any alternative from dm-crypt/cryptsetup/LUKS side was available. There is a tool called luksipc(Luks in place encryption) after further research I found the most recent documentation and a warning from the author of that tool:

Is there a way to do full disk encryption after the install?

I'm not going into the details at the moment because I don't know if you're using LVM and if you'd rather not just use ecrypfs for now and skip the hassle of full disk encryption until the next fresh installation.Īs this is still the top result on google, I want to update it with some new information. Yes and it's going to be easier if you're currently using LVM and have enough space on your system to copy all of your unencrypted system files into an encrypted LUKS partition. If I didn't enable disk encryption during installation, is there any way to enable it post facto? Besides, if you've been singularly targeted by an organization with the right means, having full disk encryption or just home encryption will not make much of a difference unless you've also established a lot of other paranoid behaviors (like: keeping the kernel in a separate pen-drive which is always on you constantly checking for hardware tampering/keyloggers and so on) Notice though that for most users just encrypting their home with ecryptfs will be enough for their needs: keeping their friends and the common laptop thieves off their private data.

Since most modern desktops can handle full disk encryption without a sweat and it adds a thin layer of security against off-line code injection, full disk encryption was added into the installer. An added bonus of this scenario is that this is quite easy to set up even after you've installed Ubuntu, by just using ecryptfs-migrate-home.Īlso, this has been the default Ubuntu setup before it changed a few releases back, adding the possibility of full disk encryption.

HOME ECRYPTFS ENCRYPTION ONLY: If you're not too worried about someone tampering your system while you're away but you still like to keep your private data safe then skip the full disk encryption and just use ecryptfs (encryption of home).

FULL DISK ENCRYPTION ONLY: If you're the only one using your computer and your machine can.

Here's a list of possible set-ups, depending on different security needs:

So, full disk encryption and home encryption are not necessarily mutually exclusive. If your system is to be shared between multiple users, this is a very nice feature to have even if you decide to add full disk encryption along with this: the safety of Full disk encryption is off when the machine is up and running while home (ecryptfs) encryption is On as long as you're logged out. The only information leak is: filesize, timestamps and number of files (with full disk encryption these are hidden as well). They look like a bunch of scrabbled/random files since filenames are encrypted as well. When you log out /home/username is unmounted and only the encrypted files remain visible in the system (usually in /home/.ecryptfs/username/.Private/).

It is very well done and tightly knitted into the default auth system so that you'll have zero usability drawbacks: when you enter your account (either from a remote shell or from the default login screen) your password is used to unwrap a secure key, which is then used to encrypt/decrypt your files in your home directory on the fly(The mounted filesystem will reside directly in /home/username). just /home?Įncryption in /home is done using a user space filesystem called ecryptfs.
