Linux directory/partition Encryption
 

I would like to encrypt several directories in all my servers and use a USB stick as a 'key'.

I want to encrypt /home, /root, /var and the swap partition. Each directory is already in its own partition. The entire thing is also RAID1 (mirrored, two harddrives).

I went through all the available howto's, readme and other stuff found in google but none could explain how to create the above setup or something similar.

I wouldn't mind creating a howto guide, but first i'd like some help from people who have done similar things and they can explain step by step the process.

btw, the systems will be re-installed from scratch, so its important to explain partitioning during the installation.

Any help would be appriciated.

Hello fellow greek! I haven't much to say about your problem, other than that linux 2.6.19 includes encryptfs by IBM which covers many of your needs, if not all.
