Mark Hoekstra of Geek Technique offers this article on how to build a fully encrypted NAS on OpenBSD.
This is one for the more hardcore hackers in the audience. He assumes a fair understanding of the Unix command line interface and familiarity with OpenBSD including its installation.
And why build your own encrypted NAS?
Well, I believe that my data is my data and not somebody elses. Iâ€™m not paranoia nor a pirate but having all my personal data in my network encrypted gives me a peace of mind. I mean, in a time where there are some private(!) organizations who think they can tell you/me/everybody what they should and shouldnâ€™t do, itâ€™s time to take some precautions, thatâ€™s all. Like I said, itâ€™s about a peace of mind and of course, because we can. ^_^
