Encrypted Filesystem.

[Jeba Anandhan A <jeba_kernel@xxxxxxxxx>]

Hi to all,
i heard lot of encrypted Filesystem available for
linux kernel.i have small idea about developing one
filesystem but i dont know how far its good or bad.

i have small question related encrypted filesystem.if
a parition contains encrypted filesystem and user put
that harddisk into another linux machine,is it
possbile to access the partition and view data.

in my filesystem,superblock contains one attribute
which is used to store one password.

while mount filesystem

get password from user
if that password == password in superblock 
mount filesystem 
else
mount fails


after mounting,


each write operation
encrypt data and write

each read operation
decrypt data and read


if it ok means,help me to implement it.
