New entropy source proposal.
Hi.
I've been playing a bit with "use sound card as an entropy source" idea.
This simple program does what I wanted:
http://people.freebsd.org/~pjd/misc/sndrand.tbz
The program is very simple, it should be run with two arguments:
% sndtest /dev/dspW 1048576 > rand.data
This command will generate 1MB of random data.
With my sound card:
