  24       <div class="date"> 1st March 2017</div>
  25       <div class="body"><p>A few days ago I ordered a small batch of
  26 <a href="http://altusmetrum.org/ChaosKey/">the ChaosKey</a>, a small
  27 USB dongle for generating entropy created by Bdale Garbee and Keith
  28 Packard.  Yesterday it arrived, and I am very happy to report that it
  29 work great!  According to its designers, to get it to work out of the
  30 box, you need the Linux kernel version 4.1 or later.  I tested on a
  31 Debian Stretch machine (kernel version 4.9), and there it worked just
  32 fine, increasing the available entropy very quickly.  I wrote a small
  33 test oneliner to test.  It first print the current entropy level,
  34 drain /dev/random, and then print the entropy level for five seconds.
  35 Here is the situation without the ChaosKey inserted:</p>
  36
  37 <blockquote><pre>
  38 % cat /proc/sys/kernel/random/entropy_avail; \
  39   dd bs=1M if=/dev/random of=/dev/null count=1; \
  40   for n in $(seq 1 5); do \
  41      cat /proc/sys/kernel/random/entropy_avail; \
  42      sleep 1; \
  43   done

  55
  56 <p>The entropy level increases by 3-4 every second.  In such case any
  57 application requiring random bits (like a HTTPS enabled web server)
  58 will halt and wait for more entrpy.  And here is the situation with
  59 the ChaosKey inserted:</p>
  60
  61 <blockquote><pre>
  62 % cat /proc/sys/kernel/random/entropy_avail; \
  63   dd bs=1M if=/dev/random of=/dev/null count=1; \
  64   for n in $(seq 1 5); do \
  65      cat /proc/sys/kernel/random/entropy_avail; \
  66      sleep 1; \

  80 <p>Quite the difference. :) I bought a few more than I need, in case
  81 someone want to buy one here in Norway. :)</p>
  82
  83 <p>Update: The dongle was presented at Debconf last year.  You might
  84 find <a href="https://debconf16.debconf.org/talks/94/">the talk
  85 recording illuminating</a>.  It explains exactly what the source of
  86 randomness is, if you are unable to spot it from the schema drawing
  87 available from the ChaosKey web site linked at the start of this blog
  88 post.</p>
