# twuewand - A TrueRand algorithm for generating entropy

## About

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.

## Installation

twuewand requires Python 2.7.
In addition, the pycrypto package is optional, but highly recommended.

To install:

    sudo python 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

## Usage

Please see the twuewand manpage for invocation options.
