Slackware 9.1 and CryptoFS

AntZero · 11-08-2003, 06:12 PM

hi,
i want to use a crypto filesystem on my new slackware 9.1 but how can i do that? i think 9.1 has a crypto patch allready in the kernel,or? if so,how can i use it? or i need things like loop-aes?

i hope someone can help me,i'm looking around the web but found nothing.

Kernel 2.4.22, included with slackware 9.1 has crypto support, and so all that is required is to use a kernel with cryptoloop support and the desired ciphers either built in or available as modules.

The file system can then be created as described at the CryptoAPI site (http://www.kerneli.org)

The above link is showing a kind of protest and couldn't find anything about CryptoAPI.

ok,i have compiled and installed the modules but than

Code:

modprobe cryptoloop
modprobe: Can't locate module cryptoloop

ok,i try it like in the readme from the cryptapi.tar.bz2

Code:

insmod cryptoapi
insmod cipher-twofisch

works fine,now i want to you as file as crypt-container

Code:

dd if=/dev/urandom of=cryptofile bs=1M count=5
losetup -e twofish /dev/loop0 cryptofile
->password:
ioctl: LOOP_SET_STATUS: Invalid argument

mh,something wrong here,but what?

There is a link on the protest page allowing access to the site.

Sorry, my original reply was incorrect. The kernel does still need a patch applied for cryptoloop support. Either ftp://ftp.kernel.org/pub/linux/kerne...p-hvr-2.4.22.0 or
ftp://ftp.kernel.org/pub/linux/kerne...-jari-2.4.22.0 should be OK.
