I figured it out. I am now using dm-crypt, losetup, cryptsetup etc.

Seems to work so far.

Yup.

I was using it on my 1.4TB RAID. Works well. Drawback?
- 32bit block counts, the maximum size is around 2TB

Maybe new versions of the userland and kernel code fixes this.

Interesting. I do not have partition size issues, I am going to use my
cryptographic file system only to store my own credit card numbers,
hence small size (300 MB).

You have 300MB of your own credit card numbers? I think you have a serious
problem!

Hi!

Well, why not put those numbers in a text-file and encrypt this with
GPG? Assuming you have normal numbers of accounts this will keep you
well under 1MB.

I would loook into crypto loops... Basically, it's an encrypted file system
on a file that mounted as a loop. You can make the fs any size you wish and
the encryption can be any of the many that are included in the 2.6 kernel.

I use it all the time and favor it over other types of encrypted storage.

Just google around for "encrypted loops"...

Cheers.

I didn't know Paris Hilton was into cryptography!

Thanks for the link. I've been looking for a container encryption program
for Linux for a long time. Windows has many programs that do this. I always
found it ironic that Windows users had access to such software while Linux
users, who are more security conscious, are left hanging.

Linux has has crypto filesystem and devices for a long long time.
lookup "cryptoloop" for the 2.x kernel.

Wow! 300 MB! How many credit cards do you have?
