Hi guys,

I just finished my first go at an entropy gathering tool for rtl-sdr,
it's licensed under GPL (will add LICENSE file next!) and available at:

https://github.com/pwarren/rtl-entropy

My aim was to have a utility that ran with a minimum of dependencies,
so it could be done easily on a raspberry pi, and without trying to
get a whole gnuradio stack working!

I'm not a crypto expert, but I've read enough to know that you really
should pass the output through rng-test or similar before using.

As I mention in the Readme, I plan on doing these tests and eventually
getting it to the stage where the entropy can be plumbed in to
/dev/random.

So, thanks for making the rtl-sdr libraries and making them easy to
work with!

Cheers
