Offline Bitcoin Armory on LiveUSB


WARNING: Allffll software component of this solution: TrueCrypt, is now obsolete and deemed NOT SECURE


Creates a self-contained offline Bitcoin Armory, on a bootable USB drive, from signed verifiable sources (,,  Your wallet remains saved in encrypted storage.

This is intended for those seeking the benefits of an offline wallet, but without dedicating a PC to this purpose.

The setup process, while verbose, will require less overall time to setupf compared to installing a fresh OS from scratch.

It’s laid out in step-by-step format with select sections labeled Recommended, which can be skipped to shorten the setup time, and performed at a later time to improve your experience with the Offline Bitcoin Armory on LiveUSB.

Create a LiveUSB

Get a fast USB 2.0 drive

A 4 GB or greater USB stick with fast reads and good outer construction will do.

Recommended: Super Talent Pico-C USB 2.0 drive, LaCie iamakey v1 USB 2.0 drive without encryption.   Fast, compact, waterproof, metal housing.

Not recommended: USB 3.0 drives, drives with hidden partitions that auto-run proprietary software, drives with wear-leveling firmware.

Create an Ubuntu 12.04 Persistent LiveUSB

    1. Download and validate the .iso image for Ubuntu 12.04 LTS Desktop to your online PC, in either 32bit (recommended) or 64bit.  Note 64bit will only run on PC’s with multi-core processors and will not work on many netbooks powered by single-core CPU’s.

    2. Do a low-level (not “quick”) format of what will become your LiveUSB drive.  Warning: all data in the target drive will be destroyed…this is not the step to be careless.

    3. With your freshly formatted USB drive, create a persistent LiveUSB:

  1. In Windows, use these instructions.

  2. Within Ubuntu, use the “Startup Disk Creator” application pre-installed in Ubuntu.

  3. For either method, you will specify the .iso image you ddownloadedownloaded

  4. For the persistent space, select the maximum allowed.

Download Armory and TrueCrypt

Use a separate, extra USB drive to transfer information to/from your LiveUSB session:

  1. Download and verify the Bitcoin Armory package for Linux, which includes all dependencies for offline installation to Ubuntu.  Match the Ubuntu version and bitcount.

  2. Download and verify the latest stable version of TrueCrypt for Linux.  Select the Standard version for the corresponding Ubuntu version and bitcount of your LiveUSB.

  3. Save both files to the extra USB drive.

Boot to your Ubuntu LiveUSB

    1. Isolate the laptop/netbook you will use as offline Armory:

  1. Remove hardwire LAN cable

  2. If your laptop is provided with a WiFi switch, turn off WiFi.

  3. Ensure the BIOS allows the PC to boot from USB.

  4. (Recommended) Alter the BIOS boot order such that the PC will boot your LiveUSB drive whenever present.

  1. With your LiveUSB plugged in, power on your PC.  If you didn’t or couldn’t change the boot order, be prepared to hit the right key to enter the BIOS boot screen and select the option to boot from the LiveUSB drive.

  2. You’ll get a dialog screen from Ubuntu.  Select the option to “Try Ubuntu”.

Test your finished LiveUSB

Test restarting your PC and booting to the LiveUSB:

  1. Depending on your BIOS settings, you many need to press a key upon startup to enter the boot device screen, and select USB as boot drive for the session.

  2. Upon startup, you should be asked for the password to your TrueCrypt volume, and validate it’s mounted in File Explorer.

  3. After your encrypted volume is mounted, use the Launchbar icon to start Armory.  Your wallet appears listed.

  4. If you plan on using your LiveUSB on multiple PC’s, test booting on all.

  5. Stretch goal: try deleting and restoring your wallet from your paper backup.

Begin using Armory:

    1. Read up on usage of Armory

    2. Try transferring small amounts using your offline/online Armories.

    3. Kiss your paranoia goodbye, now you can just be careful:

  1. With just your wallet paper backup, you can safely recreate your offline environment and survive your LiveUSB drive being lost or compromised.  Upon such event, and assuming you used strong encryption passwords, you can restore your environment and move your bitcoins to a new Armory wallet with very low risk that anyone can brute-force their way to your bitcoins.

  2. Run your LiveUSB offline Armory only on PC’s and environments you control and trust are private and secure.  Plugging your LiveUSB to an untrusted PC and/or typing your passwords where someone may be physically recording your every move are not secure practices.

  3. Keep paper backups of your wallet and encryption passwords secure.

  4. Don’t keep your LiveUSB connected while you boot to the OS in your hard drive.

  5. Don’t mount your hard drive while in your LiveUSB environment.

  6. Don’t connect to the internet while running your offline LiveUSB….ever.
