SYNOPSIS
urng* at uhub?
DESCRIPTION
The urng driver provides support for
various true random number generator (TRNG) devices connected via USB.
urng reads raw entropy from the device at a
(hardware dependent) interval and stirs it into the system entropy pool with
enqueue_randomness(9).
HARDWARE
The following devices are supported by this driver:
- Araneus Alea I and II
- Capable of delivering 100kbit/sec of hardware-generated entropy.
- Altus Metrum ChaosKey 1.0
- This device is capable of providing entropy at 10Mbit/s.
