I ported Matt Blaze's CFS (Cryptographic File System) to NetBSD.  Matt 
has bought back the changes; you can pick up the full distribution at
your choice of

	http://www.crypto.com/software/cfs-1.4.1.tar.gz
	http://www.crypto.com/software/cfs-1.4.1.tgz

Until we get around to building a package, see the regular installation 
instructions and the README.netbsd file.

CFS 1.4.1 should be considered "manufacturer discontinued" -- there is 
not likely to be any further development of the current code base.  
Matt has plans for a complete rewrite, using modern RPC conventions, 
support for ciphers with block sizes other than 8 bytes, etc., but the 
timing of any such effort is quite uncertain.
