Hello everybody,

I have downloaded KNOPPIX_V3.9-2005-05-27-EN via Bittorrents.
Checking to the isofile, I noticed that the file is signed using a gnupgp key DSA ID 57E37087, and not one of M. Knopper key (BA8F038D) as it supposed to.
Moreover, the key indicated is not referenced on http://keyserver.veridis.com
So I am wondering, if this file is safe,

By the way I looked at the dvd Knoppix 4.0, to cross check and I could not find any signature .
