4 Open and Free Disk and NAS Encryption Projects - page 2

TrueCrypt, FreeOTFE

DiskCryptor is another disk encryption solution. It offers encryption of entire disks, including the system partition, and CD/DVDs. The best part is that the partitions don't have to be empty. You can encrypt drives or partitions with existing data in place, even your system or boot partition.

Keep in mind, DiskCryptor only runs in Windows. Additionally, it doesn't let you create file containers like with TrueCrypt and FreeOTFE. It's most useful for encrypting used drives.

CryptoNAS

If you do a lot of sharing on your network, network-attached storage (NAS) servers can be quite useful. They provide a central storage spot for the entire network. They give you better functionality and control over what simple file shares of Windows, Linux, or Mac OS X provide. However, don't forget about disk encryption. Thieves can still steal your NAS server, which is probably a gold mine of sensitive documents.

CryptoNAS is a Linux-based NAS server designed to encrypt the drives you use with it. It can turn pretty much any old PC into a secure NAS server. Simply insert a LiveCD or install onto an existing Linux machine.

You can create and mount the encrypted volumes via the web-based GUI by supplying a encryption password. Then the volume is accessible on computers in the network via a Samba (Windows) share, which works just like accessing a simple shared folder. You can also access the CryptoNAS shares via Linux, Mac OS X, and other OSs that support Samba shares. Once you unmount or restart the NAS server, the encrypted volumes are locked until the encryption password is provided.

Since CryptoNAS creates the encrypted disk partitions using the LUKS volume, they are also accessible directly in Linux or directly in Windows via FreeOTFE.

For help on using CryptoNAS, refer to a previous tutorial of mine on PracticallyNetworked, another Internet.com site.
