| Hi Michael,

| No, there is no AES in it. Instead, it implements the version 1.1b of

sorry, after the reading of the linux-journals page i see my mistake.

but it should be possible to use it for encrypting a crypto-fs.

actually i'm having some problems inserting the tpm-module i downloaded
from the ibm-page

it shows a "device not found"-error
