Hi,
i used an encrypted partition using twofish-256 under gentoo with kernel 2.6.8.1 and 2.6.9. Today i installed SuSE 9.2 and would like to take over my data from that partition/harddisk. But that failed with:
requested cipher or key length (256 bits) not supported by kernel
after a long warning message:
<snip> 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. SuSE has introduced a patch which also permits short passwords with a minimal length of 8 characters for all other hashes. Hopefully this message is annoying enough that you discontinue using such short passwords. </snip>
I thought, ok lets use rmd160: # losetup -e twofish256 -H rmd160 /dev/loop0 /dev/hdb1 but that did not help at all
The twofish-module loads fine into the running kernel.
Something i missed?
I think you need the cryptoloop kernel module loaded. ciao Arvin
