Developing the CryptoCape at SparkFun Electronics

I’m about to start my second week at SparkFun Electronics as a hacker-in-residence and I’ve made some great progress. I have an initial draft design of the CryptoCape, which will be scrutinized this week by the awesome SparkFun engineers. Also, I’m working on a BeagleBone Black Cape tutorial which should help anyone looking to get started with Capes and setting up the EEPROM. On Wednesday, my last day, I’ll be giving a lunch-and-learn entitled “Crypto for Makers.” There’ll be a short primer on cryptography and then I’ll dive into project ideas involving crypto. I’m planning on ending with a short talk on submarine life, just for fun.

Ok, so this picture wasn't taken at SparkFun.  But I'm using the AtMega328p on the Cape.  Also, working at SparkFun is equivalent to taking a Master's course in Eagle CAD, so expect some nice revisions to the Hashlet!

If you are in the Northern Colorado area, I’ll be hosting a talk at Loveland CreatorSpace on Tuesday, January 21st where I will describe the hacker-in-residence experience and go into some more details about the CryptoCape and building for the BeagleBone Black.  Space is limited, so RSVP on Meetup.

At Cryptotronix, I’ve made my first international sale! I’ve expanded shipping to Canada and Europe. Check out the Cryptotronix store on Tindie for more details.

  1. Hi Datko, have you looked into trying to use the Beaglebone’s AM335x’s two hidden PRU processors for hardware acceleration for TOR or other cryptographic functions? Those two PRU’s seem like they are ripe for offloading some processes (they run at 200MHz and have access to 10 GPIOs each) to get some multithreaded hardware acceleration going.

    With TOR usage I figure there are two metrics to look at, network throughput and processing speed. The PRUs may be available to help with processing speed or usage of your crypto-cape, if it can be made to use the specific GPIOs that the PRUs have access to.
