I have problems migrating from patch-int+loop-hvr to patch-cryptoloop..
I created the cryptoloop-fs using Linux 2.4.21 with patch-int + loop-hvr and
unpatched losetup from debian 3.0 (woody).
Now, I compiled 2.4.22 with patch-cryptoloop-jari and patch-aes-asm. I'm
still using losetup from debian 3.0 (woody)..
I couldn't get the fs to work with the new kernel. losetup complained
something about the encryption type or so (Sorry, I don't have the exact
error message available now..)
I'm using aes (keysize 256).
I tried using util-linux 2.12, and encryption type aes-cbc-256 like this:
hashalot ripemd160 | ./losetup -p0 -e aes-cbc-256 /dev/loop0 /dev/vg0/lv0
But I couldn't mount the loop0 after this.. so the key was not set up like
in my patch-int+loop-hvr combo..
Any ideas?
Thanks!
