Redhat 9 -> TAOLINUX/RHEL crypto migration

[nettie <nettie@xxxxxxxxxx>]

Hi guys,

2 years ago I configured an encrypted filesystem on my RH9 server 
following the instructions on QVADIS website:

http://www.q-vadis.net/index.php?mID=stories&lng=en&art=5

today I migrated the serve to Taolinux 1.0 http://www.taolinux.org (it's 
basically a RHEL rebuild)

and I'm totally screwed :(

I spent a few hours reading newsgroup posts and crypto related 
informations, tried diffeent falvors and combination of patched on 
util-linux but unfortunately I wasnt able to sort things up.

---

My last try was using the latest util-linux v2.12 + loop-aes v2.1b:

./losetup -e aes-256 -H rmd160 /dev/loop0 /glcrypto
Password:

WARNING - WARNING - WARNING - WARNING - WARNING - WARNING - WARNING

Passwords shorter than 20 characters are considered too short and insecure.
Use of rmd160 password hash permits use of such short passwords for
compatibility with other systems that do not enforce minimum length.
Hopefully this message is annoying enough that you discontinue using such
short passwords.

WARNING - WARNING - WARNING - WARNING - WARNING - WARNING - WARNING

ioctl: LOOP_SET_STATUS: Invalid argument, requested cipher or key length 
(256 bits) not supported by kernel

---

/proc/crypto shows that my current aes module doesnt support 256bit 
keysize :(

name         : deflate
module       : kernel

name         : aes
module       : aes
blocksize    : 16
min keysize  : 16
max keysize  : 32

---

I'm quite lost, considering on this box I would like to stay with 
stock/not hand-patched RH/TAO kernels instead of building my own.

---

dmesg show that the kernel has CryptoAPI support:

[root@ns2 cipher-aes-i586-0.3]# dmesg | grep Cry
Initializing Cryptographic API

---

compiling cipher-aes-i586-0.3 didnt help :(

[root@ns2 cipher-aes-i586-0.3]# insmod ./cipher-aes.o
./cipher-aes.o: unresolved symbol unregister_cipher
./cipher-aes.o: unresolved symbol register_cipher
[root@ns2 cipher-aes-i586-0.3]# depmod ./cipher-aes.o

I'm running stock kernel 2.4.21-15.0.3.TL

Thanx a lot in advance for your time guys, I hope someone could help me 
sort this up :)

Best,

nettie
