Parallella Community

Hi there,

We are holding an info evening on embedded systems at the school where I work. Will be displaying some PI's, Odroids, arduino's and the soon to be delivered Parallella board.

Looking for a good demo to run of the Parallella board for people to see.... show off some wow factor!

Am thinking "John the Ripper" password hacker... but it would be nice to see graphically how efficient the board is working as well...

Any ideas for the best thing to demo on the board?

Cheers,

Shodruky's are pretty impressive and have that visual element, of course. So, that's mandelbrot, blobubska and kinect_test. The latter also have an interactive angle, but you would need a Kinect controller.

Thanks,

Just looking at those examples now... yes they do give that visual appeal. Great. Just looking at kinect_test now....

Do you know if there is a "version" of John the ripper though where someone could type in a password and then we run john and it tries to decrypt it? Sounds a bit simplistic, but would be nice to get some interaction happening... "Type in a password ... see if this little board can decrypt it"

Cheers

I'm afraid I don't, but from my limited knowledge of JtR it sounds possible. I guess you want them to type in the encrypted password, perhaps generated on another machine, or else have a step on the Parallella as a precursor to generate and store this, before getting JtR to attempt to decrypt it.

Hi all,

yes thanks for your help info here...

What would be good if I could get the "user" to type in say three different passwords - say one weak, one medium and one strong. Then somehow encrypt them (turn them into a hash file of some sort) after they hit enter.

Finally run JtR to see how quickly the weak passwords could be decrypted, and how long the others took. While this was going some graphical view of the CPU usage would be fantastic.

Not sure my python skills are anywhere near good enough for me to program this though.

Would it be a hard task?

Appreciate your help.

Cheers,
Martin.

Hi ZenoArrow,

Much appreciate the help - yep happy to give it a go.

Have done "a little" in python a while back so hopefully the concepts will come back to me.

Where's the best place to start?

Cheers
