Same here, this crypto stuff rocks! I posted a document and some sources for using the high throughput entropy source on linux (2.4.23 and 2.4.6test9) here: http://peertech.org/hardware/viarng/ The stock hw_random.c needs a few tweaks to support 8 byte xstore, and I wrote a new userspace entropy daemon to support low latency, high volume throughput. I should clean the code up so it is usable... Best regards,
