I was trying to extract an un-exportable key from OS X Keychain. I used this tool to extract the key. The tool gives me a hexdump of the private key.

What’s the smallest controller you’ve ever used? [BitBuilt] forum user [Madmorda] picked up a cool little GameCube controller keychain with semi-working buttons at her local GameStop. As makers are wont to do, she figured she could turn it into a working controller and — well — the rest is history.
This miniaturized controller’s original buttons were essentially one piece of plastic and all the buttons would depress at once — same goes for the D-pad. Likewise, the original joystick and C-stick lacked springs and wouldn’t return to a neutral position after fidgeting with them. To get the ball rolling, [Madmorda] …read more

Sometimes the simplest projects can be the most impressive. Most of the time our simple projects are not as neat and elegant as our more time consuming ones.

The heart-shaped key-chain has one goal – to flash a pair of red LEDs when a capacitive button is touched. He was able to accomplish this with a PIC12LF1822 and a handful of supporting components. We’re quite impressed with the …read more

In the osx keychain I was browsing certificates that my school forces me to trust and came upon an intermediate certificate authority that was signed by an untrusted user, I believe that would be me and was wondering what the certificate trust would default to when “no value specified” is what trusting ssl certificates is set to? I am also wondering what type of certificates this intermediate certificate could issue/sign?
The images below are of the intermediate root ca, as a side note this ca has already been used to sign certificates for x.509 basic policy and extensible authentication protocol(EAP) which makes sense since this is used to connect to wifi.
Listed below are some of the questions I had about how my school’s wifi is set up and how I can protect myself
