You have two basic choices: Crypto patch for 2.4 or Jari Ruusu's
loop-AES. Loop-AES can be used without patching a kernel--but it must be
compiled without loopback support. Instead utils-linux is patched so
mount, umount and losetup have AES support.
Most of the kernel patch problems may have been overcome. I don't think
Jari's approach has ever caused data corruption. If you read through the
archives you'll be up to speed with developments. I understand that
sometimes if you upgrade your kernel to 2.4 with the International patch
you can't access a volume generated with a 2.2 kernel! At the time I
read that a solution had not been found.
