Re: random translator

[Rian Hunter]

Like a lot of the GNU/Hurd user crowd I was faced with this same problem 
and also like a lot of the GNU/Hurd user crowd I just wrote my own. My 
translator setup is made for Debian and it has some sample boot scripts 
tha start up egd and compile my translator. There is a readme file in 
the archive, i don't really remember all the whosits and whatsits about 
how it works but the gist is that it is a HURD translator that is 
install in random and urandom and when given a read request it siphons 
the bytes from egd. It implements the same behavior as Linux and FreeBSD 
random and urandom devices.

You can find it at

The quality of my random translator should be pretty sound, given that
it uses GnuPG's random pool.  However, it may need to be extended a
bit to poll entropy from a kernel device.
 

So there should be a separate entropy translator? That would actually
eliminate the issue of how to use hardware entropy generators
(including that stuff that supposedly comes on some of the Intel
boards/procs).

The only biggish thing that's missing is a random device in gnumach
which delivers entropy from the hardware (timing IRQ events, etc.
It's not perfect, but the best thing you can get from standard PC
hardware).
Thanks,
Marcus
