Summary
Based on the delivery of EncryptedPrivateDirectory in Ubuntu Intrepid, this specification describes the next steps to extend that work to provide a seamless mechanism for encrypting a user's entire home directory, mounting it on login, and un-mounting it on the last logout.
Release Note
The Ubuntu Jaunty Jackalope (9.04) release will enable per-user home directory encryption.
Rationale
The EncryptedPrivateDirectory work proved the usefulness and stability of the Linux kernel's ecryptfs cryptographic filesystem. Encrypting only ~/Private directory, however, requires Ubuntu users to consciously store sensitive data in that location, and manually linking that data to traditionally locations.
Use Cases
Assumptions
Design
You can have subsections that better describe specific parts of the issue.
Implementation
This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:
UI Changes
Should cover changes required to the UI, or specific UI that is required to implement this
Code Changes
Code changes should include an overview of what needs to change, and in some cases even the specific details.
Migration
Include:
- data migration, if any
- redirects from old URLs to new ones, if any
- how users will be pointed to the new way of doing things, if necessary.
Test/Demo Plan
As of 2008-12-02, you can test this by:
Install the adduser and ecryptfs-utils packages in the following PPA:
- Add a user with an encrypted home directory as root, with:
# adduser --encrypt-home testuser
Login as testuser on the console, through the GUI, and via ssh. Ensure that all programs work as expected. Log out of the console/GUI/ssh. Ensure that the home directory is not mounted and that the data stored in /home/testuser/.Private is encrypted.
Unresolved issues
There are two other specifications, solving related issues:
- Encrypting Swap Space
- GUI for eCryptfs
