It is open hardware also, with a schematic supplied, open source driver (not a kernel driver yet), I was very happy to support this project. I have looked for usb equivalents, btw, and haven't found anything inexpensive. And in the case of cero I'd wanted something that could run on the internal serial header... I note that theoretically the BBB also has an on-cpu hwrng but documentation on it from TI is lacking. Perhaps someone could lean on TI to free that information up in the post-snowden era? (my take on it is the more hwrngs the better, one from china, one from russia, one from the USA...) /me goes back to converting his dns/mail/vpn server over to a BBB.... > > > > > > On Saturday, February 1, 2014 11:11pm, "Dave Taht" > said: > >> I am still quite irked by having to use /dev/urandom for important >> tasks like dnssec key generation, and in wireless WPA.
