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. - Ian -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBMeqk5EZRiTErSPb1AQEbdwQAl/ZyhK+ZczFnfUFm9wVNGAq9MBSGNmZc t1xS2G6urjit3IvHn0ZYSCzkwUj00Hun4FLdFkp0i45M2PWGSJMZtr/Mx7Xua9yr 2uw1p3bN1iId8JrQOGuo1aCTm8rTUh30OW2cL+jPM+RBWgLGg9YcBUQzO7OLoqeM xpROxmPL8CI= =pezJ -----END PGP SIGNATURE-----
