The original question:
I'm looking for software package for crypting filesystem
in device or directory basis. Any suggestions?
The solution:
People suggested a couple of possibilities. The one which I used
was CFS (Cryptographic File System). CFS can be found from
http://www.cryptography.org/ under the 'disk' catefory.
Note that CFS is under US export laws and you'll propably
compromise US national security if you download it from there
so you should find alternate site if youre not US citizen.
ftp://idea.sec.dsi.unimi.it/ might be a good place to start.
There is one slight problem with CFS. The package will compile
and install a binary named ssh, the same as Secure SHell (the
crypted 'telnet' client). I renamed the ssh which came with CFS.
On the otherhand CFS was easy to install and I got it working
without any hassles.
Other suggestions were:
TCFS (Transparent Cryptography File System), which can be
found at http://vales.uni.net/tcfs/
LOFS (LOopback File System), which is bundled with solaris.
rsync + ssh combination, which propably works but seems
a bit kludgish to my taste.
AFS (Andrew File System), didn't do any research on this. Check
http://www.cis.ohio-state.edu/hypertext/faq/usenet/afs-faq/faq.html
http://www.datafellows.com/ also has something in 'Protection of
Confidential files' section. Didn't check that out though.
