twuewand is software that creates hardware-generated random data. It accomplishes this by exploiting the fact that the CPU clock and the RTC (real-time clock) are physically separate, and that time and work are not linked.

twuewand requires Python 3. In addition, the pycrypto package is optional, but highly recommended.

To install:

sudo python3 setup.py install

On Linux systems, a small C program is also available called rndaddentropy. This is a wrapper for the RNDADDENTROPY ioctl, and is used for directly adding entropy to the Linux primary pool. Please see its manpage for more details.

sudo make -C rndaddentropy install

Please see the twuewand manpage for invocation options.
