vncrypt ported to CURRENT

Now you can encrypt your vnode-based md devices.

You have to recompile your kernel with

device md
options MD_CRYPT

or do

kldload md
kldload mdcrypt

Timeout feature not implemented, but otherwise this patch is compatible with vncrypt (both disks and keyfiles).

Please report any problems.

vncrypt beta3 released

A new algorithm was added: AES (Rijndael) in "multi-key" mode. Each disk sector encrypted with its own key, derived from one master key.

A user-level decryption utility was added and can be used for testing bf-cbc encryption mode.

NOTE: this version will compile only with recent 4-STABLE kernels since the blowfish interface in the kernel was changed in late March.

New encryption mode added to vncrypt

I've commited new encryption mode support. It encrypts each disk block on unique key, generated from master key and block number. Possibly it will make linear/differential cryptoanalysis more difficult.

Version 1.0 will be released after i write regression tests for all three modes to ensure they are work correctly.

If someone can translate russian docs to english, your are welcome. Me english is not good enough for this, as you can see :)... read more
