I'm going to need to store some files on a USB stick with a decent level of encryption on them. My first thought was to use truecrypt, as I do this on my laptop already, but it appears that it does not work on computers that you are not admin unless an admin has already installed it. As I'll be using the USB stick with relatively locked-down computers that's not an option. I'd much prefer to use some software rather than buy a hardware-encrypted USB stick, but are there any software options that will work? I've already searched through the threads here and I can see that Rohos keeps on getting suggested by one person, but am a little nervous because it's always the same user so would prefer to see what others think.
