If you are running Red Hat Linux and want the Cryptographic File System (also available for most BSD-derived Unix systems and most current Linux releases), go to http://www.replay.com/redhat/cfs.html If you are running Linux 2.0.X and want the Transparent Cryptographic File System (improves on Matt Blaze's CFS, they say), go to http://vales.uni.net/tcfs/ - d.
These are just NFS servers. Do there exist any programs which actually keep the contents of the filesystem on your hard-drive encrypted? mib wrote: > > If you are running Red Hat Linux and want the Cryptographic File System (also > available for most BSD-derived Unix systems and most current Linux releases), > go to http://www.replay.com/redhat/cfs.html > > If you are running Linux 2.0.X and want the Transparent Cryptographic File > System (improves on Matt Blaze's CFS, they say), go to > http://vales.uni.net/tcfs/ > > - d.

Ok, so that was an especially clueless question for me to have asked. Oh well. :) mib wrote: > > On Sat, Dec 12, 1998 at 05:57:42PM +0000, Michael Hohensee wrote: > > These are just NFS servers.
