I have searched for encrypted filesystems for un*x. Is there any better
encrypted filesystems than the ones I have found for *bsd (+freebsd)..?
Note that some comments are based on what others have said. I think it's
important to keep in mind the different approches used, per-file vs disc-block
aswell.
I'm looking for something convinient to enrypt cdrom's. Which will also suit
dvd-r media. It should preferable be portable and not require specific kernel
hacks. To ensure feature stability & availability.
The encrypted filesystems arena looks like a collection of software rather than
a unified solution across platforms.
Which operating systems manage to effectivly to use encrypted swap..?
Openbsd seems to handle it nativly, while freebsd could possible use
vncrypt in conjuction with swapon, or cfsd with swapon-file. Netbsd might use
cgd?
==== Interesting encrypted filesystem projects ====
The following is directly usable on freebsd:
cfs 2 GB limit (nfsv2), easy portable
vncrypt Unstable? (and needs kernel module)
geom(4) Modular disk I/O request transformation framework
The following seems usable althought might require some work:
loop-aes Only ported to linux so far
http://sourceforge.net/projects/loop-aes/
cryptfs Port for freebsd available (btw, check out FiST!)
http://www1.cs.columbia.edu/~ezk/research/cryptfs/index.html
http://ftp.vit.edu.tw/pc/programming/hacktic/disk/
BestCrypt Source avail, 30day trial period.
http://www.jetico.com/
Available, BUT not directly applicable:
PPDD Linux specific, needs 100MHz+ pentium
pgpdisk M$/win+Mac binary only
http://mail.lab.net/lists/archive/cryptography-exploder/2003-February.txt
PGPdisk + Linux ..?
Janis Jagars, handle Disastry
tcfs Alias cfs? (available for Linux,Netbsd,Openbsd)
http://www.tcfs.it/
ncryptfs Follow up from cryptfs, not publicly released yet.
