Set up an encrypted Debian system

| | Comments (0) |

I've done some experimenting with encrypted filesystems in Debian, which are easy to do with the Debian installer — and which are just as easy to do in Ubuntu if you use the alternate installer.

Like I said, it's easy to do and to manage, unless you want to have a bunch of partitions under a single passphrase. This blog post helps you figure it out.

While full encryption is something you might want to use on a home desktop, although I wouldn't, it's almost mandatory for a laptop. If the thing gets stolen, whoever gets that drive has access to everything on it. And you really don't want that happening, do you?

Right now, neither of my two Linux laptops are encrypted, since I use them for testing and need to see one system's hard-drive partitions from the other, but in the near future, if I decided to single-boot either or both of these, you can bet I'll be encrypting the hard drive.
