+[Savannah task #5130: random translator](http://savannah.gnu.org/task/?5130)
+
+See the attached [[mbox.bz2]] containing all the emails concerning this topic
+which I was able to gather from public archives.  (!) This is not up-to-date
+anymore, as [[MichaelCasadevall]] is currently working on this.
+
+# Description
+
+Sources of entropy are for example disk access latencies or keystroke patterns
+or behavior on networks.  This suggests that for implementing a random
+translator a kernel part is needed as well, to gather that entropy.  That
+kernel part would then export the gathered entropy via a kernel device, named
+perhaps `entropy`.
+
+# Setup Pseudo Random Devices
+
+Stuck getting SSH to work? You need a pseudo random generator (PRG).
+
+There are several solutions to the lack of `/dev/random` and `/dev/urandom`,
+but they are not yet in the default installation.

+* Marcus' work can be downloaded at
+  [random.tar.gz](ftp://alpha.gnu.org/gnu/hurd/contrib/marcus/random.tar.gz).
+  (Identical to <http://kilobug.free.fr/hurd/random-64.tar.gz>?)
+  * [A patch](http://mail.gnu.org/pipermail/bug-hurd/2002-August/010248.html)
+    that was probably already incorporated from August 14, 2002.
+  * Clemmitt Sigler [reported
+    success](http://lists.gnu.org/archive/html/help-hurd/2002-10/msg00076.html)
+    October 11, 2002 and Marcus [described
+    some](http://lists.gnu.org/archive/html/help-hurd/2002-10/msg00081.html) of
+    the internals.

+# Setup Tips
+
+Here are some tips on how to actually setup the two random devices using
+Kilobugs' [random-64 server](http://kilobug.free.fr/hurd/random-64.tar.gz).
+His tarball is a complete Hurd server including a pre-built binary - so you
+don't need GCC or magic fingers for this!  :)
+
+After untaring the package you copy the random binary to the `/hurd`
+directory.  Then you setup the translators for random and urandom.
+
+    # settrans -c /dev/random /hurd/random \
+               --seed-file /var/run/random-seed --secure
+    # settrans -c /dev/urandom /hurd/random \
+               --seed-file /var/run/urandom-seed --fast
+    # chmod 0644 /dev/random /dev/urandom
