I learned how to create and use encrypted drives in an Intermediate Linux course. I found this article that covers it pretty well if you want to try this yourself and didn't take notes. :) Just skip the first section titled, "Linux encryption methods." We used LUKS as does the rest of the tutorial.

Also, I don't believe luksOpen worked on my system. Same with luksClose. I just used 'open' and 'close' respectively. There's also a reference to luksDump. You can ignore that part - we didn't cover it.
