Hi,
actually it was in the kernel 2.4-days when I tried, but I guess, it
mostly works along the same lines.
What I did then was an encrypted file which I mounted (with -o loop) as
partition. Your hard drive should behave the same, but I would suggest
you to check whether you want to encrypt the whole drive or rather just
a part of it (say 2 GB) which you use for the sensitive data.
Check back on the discussion about security versus safety ;-) My
suggestion is to keep the amount of encrypted data low so at least some
attacks on the key (the ones which need a lot of data to work) are harder.
The howto was something like this:
1. check if your kernel has the modules for encryption.
2. create a file (dd if=/dev/null of=mycrptfs.file bs=1024)
3. create an encrypted fs in it
4. mount manually each time you want to use it, giving the password
Though I cannot tell you the exact commands from memory, you should be
able to find all the information you need. Especially as you said you
found an old howto, check back if it lists the same procedure and give
it a try! The stuff inside the kernel did change since 2.2, but the user
interface did stay mostly the same ;-)
Have fun!
PS: I will not give you any warranty ;-)
