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?

Well, it seems encryption now works, and stego works, but stego'ing an encrypted filesystem doesn't. :-( I'll keep looking at it... - Ian -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBMe5TWkZRiTErSPb1AQHpUgP+MnrTrgPoGLL8WHugMsvhBZfQ45mj5mdj ZpSO/bjtn/YUtsmzmGOr2EjWWHesIZ+Xm30g16qLD/TAxnYpShZrvQH5YoYwZzLh y0T937Q+ZjOMDKJLFsVghA4jB2iBbwbp7EAMIQLZHsxZYj+pbnE9SUZuwgQlcmAC OyMfK0ZBs9g= =T3ID -----END PGP SIGNATURE-----
