July Meeting: LUKS Disk Encryption in Windows

When:

Thursday, July 18, 2024 @ 7:00pm

Where:

Wright State University
Russ Engineering Center, Room 302

We will also have an online presence via the Zoom web conferencing service.

Meeting ID: 876 0225 4357

If joining a meeting from a Windows PC, the Zoom client will automagically download and attempt to install. For those using Linux, you can download the free (not Free) Zoom client from this page. It’s available for a variety of distributions.

For those attending in person, we will most likely adjourn to Milano’s afterward for food and socializing.

Presentations/Topics:

The Linux Unified Key Setup (LUKS) is a disk encryption specification originally intended for Linux. LUKS implements a platform-independent standard on-disk format for use in various tools. This facilitates compatibility and interoperability among different programs and operating systems, and assures that they all implement password management in a secure and documented manner.

JMB will show us how to configure a Windows 10 or Windows 11 computer to access a LUKS-encrypted USB-SSD drive.

The key features are:

  • In Windows 10/11, access, store & backup files to a locally mounted USB-SSD.
  • The ext4-formatted USB-SSD is Linux Unified Key Setup (LUKS) encrypted.
  • Only the owner of the computer has the decryption “key”.
    • The key (passphrase) can just be memorized, written on paper, etc.
    • The key can but does need not be stored on any electronic device.
  • Use free and open source software (FOSS).
  • Not reliant on any cloud-based storage.
  • Use a device that can be:
    • Easily attached / detached
    • Physically stored in a secure location of one’s choosing
    • Small and reasonably portable
    • A capacity that one’s budget will allow (100’s GB / 1+ TB)
    • Affordable and incur only an initial cost (no subscription fees).

As always, any news, discussions, and questions about Linux / Open Source topics are welcome.

Presentations/Topics:

GNUCash is an open source accounting system appropriate for most personal or small business accounting needs. The interface is based on a “checkbook” feel similar to Quicken. But the system itself is actually based on dual-entry accounting principles, and does not attempt to hide this from the user. As GNUCash allows for storing the data in a relational database, using the data, either for reporting or extensibility, is very simple.

Ben Kendrick has been using GNUCash for personal accounting continuously since 2016 and for small business purposes since long before that. He will introduce us to the program and how it can be used in both of those contexts.

Presentations/Topics:

JMB will demonstrate a video security system based on a Raspberry Pi running Raspberry Pi OS or Ubuntu Linux and a desktop PC running Ubuntu. The system can make use of webcams, dash-cams, or Android phones. And it’s all based on Free and Open Source software! He will show how to configure the software to do:

  • Time-lapse recording
  • Record video based on motion detection
  • Email a photo when motion is detected
