http://mail.nl.linux.org/linux-crypto/ 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. Regards, Adam
