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 2.7 or later, and will work on POSIX operating systems. rndaddentropy support is limited to Linux.
user@host:~$ twuewand $(($(cat /proc/sys/kernel/random/poolsize)/8)) | sudo rndaddentropy Generated 512.1 bytes, output 512 user@host:~$ cat /proc/sys/kernel/random/entropy_avail 3256
twuewand development is managed with git, and is pushed to GitHub, where patches and merge requests are accepted.
