Cryptographic File System

The Cryptographic File System (CFS) is an encrypted file system based on an NFS daemon that can be used under various Unix-like operating systems (such as BSD and Linux ). It was developed by Matt Blaze at AT&T Research and released under the BSD license . The encryption methods supported by Matt Blaze's current CFS version are DES in hybrid mode with two keys, 3DES with three keys, Blowfish with 128-bit key, MacGuffin and SAFER-SK128.

Features of CFS:

• Easy installation and maintenance
• Also works on NFS shares
• Backup of the data to an open directory during operation
