[menkveldj] built a service that encrypts files which self destruct in 24 hours. The download link can only be used once. If the wrong people were to get the link and download the file, they’d need many years on a pretty powerful computer to crack the 256AES encryption.
The sender shares a file that is encrypted client side using a password generated Pbkdf2 key to encrypt the data before uploading it to the s3 storage service. The sender is then provided the one-time-use link to share with the recipient. After the first download, or 24 hours, the link and the encrypted file are both deleted. The receiver must enter the same password to decrypt and recover the file. No one but the sharer and receiver know what the actual file is.
It’s still work in progress, so chime in with your comments and suggestions. To dig into the code, check out his repository on Github, which also has instructions to build and run it if you’d like to do your own version.
Oh, and you’ll like this. If want to thumb your nose at the powers that be, the site has a redirect for the whimsical domain: NSAfu.com.
Here’s how you can have a hands-free, no worries about the battery, Android experience while you drive. [Steve] removed the head unit from his car and replaced it with a Samsung Galaxy SIII Android phone. The look is pretty nice, but we do have a few suggested improvements if you try this one for yourself.
It started simply by removing the factory stereo which left a double-height opening in the dashboard. [Steve] cut a piece of wood to fit the gaping hole, painting it a grey that would compliment the interior colors of the car. The phone is mounted on this plate, with plenty of room for the USB and audio cables. From there it is finished up with another wooden plate which has a cutout for the touch screen. See the final project, as well as glimpses of the installation, in the video after the break.
[Steve] demonstrates using the GPS features and playing music. We’d improve this in a couple of ways. First off, using something like the IOIO board you could add a physical volume knob, which we’re not interested in giving up for a touch screen quite yet. If you were willing to go the extra mile, a CAN-BUS chip could be added too that would monitor button presses from the steering wheel music controls.

With each passing day the rate we acquire digital media increases (we don’t even bother unpacking our CDs when we move anymore). Large publishers have started moving away from DRM, which means we’ll be buying even more digital media in the future. Acquiring all of this nonphysical property puts importance on not just making it easily accessible, but also protecting it from destruction. Slashdot asked for reader suggestions of what NAS to buy; we’ve compiled some of the options below and want to know what you use.
