Hello!
I want to encrypt my existing home directory (I don't mind losing the 
files, actually, I can make a backup) and the swap partition.
Is there an easy how-to to help me do that? I looked around but all I 
found was some very long guides on how to change the file system to an 
ecrypted FS.
By the way, my home partition is reiserFS.

Thanks!
