The website is live! The first Cryptotronix product will be the Hashlet, a BeagleBone mini-cape (capelet) that will provide SHA 256 on dedicated hardware with an isolated key. I’m revising the board from the picture to include I2C test points and a cleaner silk screen.
I’m developing the software to interface with Atmel’s ATSHA204 module for use under GNU/Linux and I will make it available under the GPL. The Hashlet is designed specifically for the BeagleBone Black, but if you would like to use this on a different platform, contact me and I can see if I can design you a PCB for your application.
So stayed tuned!
