How to Encrypt Your Home Directory on Ubuntu 22.04

Encryption is a process of transforming data into an unreadable form that can only be accessed by authorized parties. Encryption can protect your personal and sensitive information from unauthorized access, theft, or tampering. One of the ways to encrypt your data on Ubuntu is to encrypt your home directory, which is where your personal files and settings are stored.

This gist will describe how to encrypt your home directory on Ubuntu 22.04 after installation. This method is useful if you have already installed Ubuntu without encryption and want to add it later. It will also work on other versions of Ubuntu that use the ecryptfs-utils package for encryption.

Backup Your Data

Please make sure you have created a backup of your system/files before proceeding with the encryption process. This process may involve significant changes to your system, and having a backup ensures that you can restore your data in case of any unexpected issues during the encr

fscrypt to encrypt existing user home

NOTE: I no longer rely on this procedure, as I've become more concerned about data corruption than privacy risks. But I also now only travel with a machine that has been privacy hardened and scrubbed of most private data, relying on secure cloud storage (Proton Drive) to retrieve any sensitive materials I may need.

Open source fscrypt provides native encryption for ext4 filesystems on Linux. With it you can encrpyt folders within a disk partition, including user folders. It cannot encrypt files in place, so data must be backed up before proceeding.

The process described below has only been tested on Ubuntu 22.04 LTS Desktop after install and user home creation. All device filesysystems are ext4. The /home directory is mounted on its own dedicated partition (e.g., "/dev/sda3"). I'm doing this to secure the personal data on a laptop from common theives, not state actors or anyone who can get access to the machine while it's running. Your Mileage May Vary. Because.
