More ciphers can be loaded as modules. Loop-AES comes with just one cipher
built in. For example, to use twofish cipher from SuSE kernel sources all
you need to do is copy the drivers/block/loop_fish2.c file to some
directory, and the compile it with a Makefile like this:
LINUX_SOURCE=/lib/modules/$(shell uname -r)/build
TD=$(shell pwd)
all:
cd $(LINUX_SOURCE) && make SUBDIRS=$(TD) modules
modules:
$(CC) $(CFLAGS) -DKBUILD_BASENAME=loop_fish2 -c loop_fish2.c -o loop_fish2.o
mkdir -p $(INSTALL_MOD_PATH)/lib/modules/$(KERNELRELEASE)/block
cp -p loop_fish2.o $(INSTALL_MOD_PATH)/lib/modules/$(KERNELRELEASE)/block
depmod -a
And then use it like this:
make
modprobe loop_fish2
losetup -e twofish128 /dev/loop0 /dev/hda666
mkfs .....
losetup -d /dev/loop0
