This is a one-time post to announce that the Hashlet, a secure
authentication mini-cape that I've developed, is now available on Tindie
The Hashlet provides a hardware random number generator, implements the
SHA256 algorithm in hardware, and enables Message Authentication Codes
(MACs) through keyed hashes. It communicates with the BBB over I2C.
I've also developed a command line application that abstracts the details
of the 80 page datasheet, which is available as GPLv3 code on Github .
The hardware design is also on the GitHub page.
Tutorials are posted on my blog .
p.s. I'll be at SparkFun Electronics next week as a hacker-in-residence
working on the CryptoCape!
