How to install Debian linux on a encrypted usb drive

It’s amazing what people can come up with, but this tutorial will show you how to install Debian Sid onto a usb drive with an encrypted root partition. It actually makes sense since only the boot partition is viewable and thus, the linux can boot straight into an encrypted root partition as long as the modules are compiled into the kernel at time of boot.
In any case, if you’re lost from what was just said, or you really don’t care and just want the tutorial, here it is.
You don’t really have to have just Debian on there, but there are certain applications and modules you must have to actually make this run. Debian just provides the packages already to do it easily.
