Skoncil som, ako aj predtym na losetup

# losetup /dev/loop5 /data/matt/encrypted.part -e aes   
Password: 
ioctl: LOOP_SET_STATUS: No such file or directory, requested cipher or key length (128 bits) not supported by kernel

# losetup /dev/loop5 /data/matt/encrypted.part -e aes256

ioctl: LOOP_SET_STATUS: No such file or directory, requested cipher or key length (256 bits) not supported by kernel
