Message-ID: <475AF241.5000809@garzik.org> Date: Sat, 08 Dec 2007 14:36:33 -0500 From: Jeff Garzik <jeff@...zik.org> To: Matt Mackall <mpm@...enic.com>, Theodore Tso <tytso@....edu> CC: Mike McGrath <mmcgrath@...hat.com>, Jon Masters <jonathan@...masters.org>, Alan Cox <alan@...rguk.ukuu.org.uk>, Ray Lee <ray@...rabbit.org>, Adrian Bunk <bunk@...nel.org>, Marc Haber <mh+linux-kernel@...schlus.de>, linux-kernel@...r.kernel.org, hmh@...ian.org Subject: entropy gathering (was Re: Why does reading from /dev/urandom deplete entropy so much?) As an aside... Speaking as the maintainer rng-tools, which is the home of the hardware RNG entropy gathering daemon... I wish somebody (not me) would take rngd and several other projects, and combine them into a single actively maintained "entropy gathering" package. IMO entropy gathering has been a long-standing need for headless network servers (and now virtual machines). In addition to rngd for hardware RNGs, I've been daemons out there that gather from audio and video sources (generally open wires/channels with nothing plugged in), thermal sources, etc. There is a lot of entropy that could be gathered via userland, if you think creatively.
