Encrypted Home Directories?

["Sumit Dhar" <ml_dhar () yahoo com>]

Hello Everyone,

Here is something I would like to do: (Could someone tell me if it is
possible on Linux)

-Every user's home directory is encrypted. No one other than the user
(including root) can read the files/directories of that user.
-Every time a user logs in, he/she will need to give a password to decrypt
his/her stuff.
-The root can delete the users files, but not read them.
-The whole process should ideally be completely transparent to the user.

Any pointers to programs that can do this on Linux??

With Regards,
