I had the need to consider encryption of a flash drive for various reasons. Hell, you could justify it under “don’t be stupid” if you’d like. Having not really ventured into this arena before, I thought I’d write down the step-by-step-guide for anyone who just wants security without thinking about it.
Optional step 2 will explain all that’s required in detail but the following gives the TLDR version.
- Download and install TrueCrypt
- Optionally read the Tutorial
- mount/insert flash device
- start TrueCrypt
- click “Create Volume”
- pick the location you want on your flash drive
- select “Serpent-Twofish-AES” if you’re just encrypting documents etc; larger file volumes than this would be slow
- select the maximum size that you’d like the volume to take. This should be based on your expected usage. 5GB should suffice for hundreds of word documents
- enter a good password e.g. lk#J4z._1Q41-lN$1″H6c!O
- click “finish”
Now you’ve got a “container” that’ll be heavily encrypted. What you’ll need now is to tell TrueCrypt to “mount” it.
Mounting your new volume
- Open TrueCrypt
- click “Select File” & navigate to your previously created container on your flash device
- click “mount”
- enter the password
Now you’ll have a mounted volume assigned to a “drive” letter e.g. “K”. Stick your files in here and they’ll be included in the volume for encryption.
When you’re ready to remove the device make sure you “dismount” in TrueCrypt!
