Encrypt F10 LiveUSB w/Persistent install

[zackf]

I saw this questions a few months ago, but never saw a response so rather than drudge it up I'd thought I'd start new since F10 is out.

I have used the LiveUSB tool (on Ahem...a largely distributed OS developed in Washington State) to make a LiveUSB install on my 8Gig drive. I want to carry this drive on my keychain but in case they get jacked I just wanted to have it encrypted.

I use it right now to do online bill pay and such but obviously I don't want to carry that info around if my stuff isn't as secure as it could be.

So all in all my question is:1) Can I encrypt the Filesystem since it's already been installed?

2) If not is there a way to install it in such a way that it's encrypted?

I have seen a checkbox option to install F10 encrypted on a normal install on an HDD.

I'd also be interested in any opinions to enhance or add to securing a LiveUSB stick.

1) You have to install with encryption. Anything else is tricky
2) Fedora 10 does encrypt /home by default. Install livecd-tools and look at the command line options if you need to customize it

Very good. I figured I'd have to reinstall. I didn't even know there was a package for it in Fedora, I had just read about it on lifehacker a while back and have gotten more and more interested in it ever since.

Hi,

Yeah, you have two packages

1) liveusb-creator - cross platform gui
2) livecd-tools - livecd-iso-to-disk is a command line script that converts a live image into a bootable usb. Number of options there.
