Nicholas Leon <nicholas@binary9.net> has created tools that allow DES and IDEA encryption at the device level for the Linux kernel. Some of the patches are in the 2.0.4 kernel, and the rest can be found at
Yep, you can mount encrypted files or partitions as filesystems. (sorta like securedrive/securedevice for messydos.) Nifty stuff...
Except that last I checked (2.0.6) it was completely insecure. The DES-encrypted filesystem ignored your password and always used a key of all 0's (which is a weak key in DES, to boot). I've been touching it up to do DES and IDEA _right_ (CBC mode within each block, IV based on block number), and plan to put in some simple stego as well.

Hrmm.. Sounds interesting... how long till your patch is done? --Deviant -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQEVAwUBMevscDAJap8fyDMVAQE4Dgf8DMS7BeiCQQvbzsF1d1egJPzv1TPW3y+J Sy8LglsqPxkYs4NynN6xwtWupKrkDUb5J5GjzkzOVD85NTlCxHxufiU5zi2u3lWV /+a6sybvIKR+MikogveQFqQqZTngFeIJBnAUdPIfybQz2gubGGdEJW0zv7eDvFlX GnWDkYpRcZbq3MiF188oRAjrSOUhJn2htFYkRaYLvuKwASaki4yfMShqMA4BYclx etxpj2lIXeJQJuF1iGyNKjGGWKaPhZYXRHT+rThufYczsUHdjb1kzdJ+dbfhAi7H OY204pjv/FhZ/ny3KFK5cqP38vXQex76IO16v7mrttmRpmbOCT9stg== =BliQ -----END PGP SIGNATURE-----
