Secure FileSystem (SFS) for DOS/Windows

Note for NTFS Users / Users of Runtime Software products

Products from Runtime Software like System Info and GetDataBack will occasionally erroneously report NTFS disks as containing SFS partitions. This is due to a bug in the Runtime Software products, which decide that finding partition type 42h on a Windows machine indicates that it's running the SFS real-mode MSDOS device driver rather than being an NTFS dynamic partition marker. See this news posting for more information on how to fix this. You may also want to report this bug to Runtime Software, although since it's remained unfixed for more than five years now it doesn't look like they're in a hurry to correct this.

In-depth analyses of various security aspects of the software
Complete design and programming details necessary to verify the algorithms used in SFS

The latest update release of SFS is version 1.17, which is available from the University of Hamburg archive site. This site can be rather slow, there is a mirror at the University of Milan archive site. Bandwidth to both these sites is limited outside Europe.

The JCFG utilities can be used to enhance the performance and ease of use of SFS.

Version 1.20 is almost ready, but since I'm very busy I haven't had much time to finish it. In 600 million years the sun will go out. I may have to finish 1.20 in the dark.

There is a free portable encryption library which contains the encryption code used in SFS, as well as a number of other encryption and hash algorithms. The library contains high-level encrypted object management routines which make implementing or adding encryption functionality to an existing program a breeze. The library is supplied as source code for Unix, DOS, Windows, Macintosh, and the Amiga, and also as 16- and 32-bit dynamic link libraries for Windows.

The Intelligence and Counter-Intelligence page contains links to intelligence agencies and resources and commercial intelligence and industrial espionage information.
The Law Enforcement, Intelligence, Investigative, and Other Intersting Sites page contains another contains another large collection of links to intelligence agencies, law enforcement, and security organisations.
The Terrorism, Intelligence, and Crime page is another page with links to intelligence and law enforcement ogranisations.
The Security and Encryption page contains links to security archives, companies, archives, software, anti-virus information, and assorted other information.
The Encryption page contains links to references on encryption, papers and publications, utilities and services, crypto policy, digicash, and related subjects.
OCP's Security and Privacy Related Items page contains a large number of links to virtually anything to do with security and privacy (too much to list here).
The Cryptorebel and Cypherpunk page is another large collection of links to encryption and security-related Web pages and FTP sites.
Ron Rivest's Cryptography and Security page has links to bibliographies, government sources, non-profit organisations, commercial enterprises, university sites, newsgroups and FAQ's, and computer security people.
The SAIC Security Documents page contains links to information on firewalls, WWW security, intrusion detection, UNIX security, the internet worm, computer attacks and countermeasures, networking security, trusted systems, newsletters, and miscellaneous security-related documents.
The COAST Security Archive Index page contains pointers to the collection of security-related programs and documentation contained in the COAST security archive, covering such diverse topics as access control, authentication, commercial security packages, email security, encryption, firewalls, intrusion detection, Kerberos, legal issues, network and password security, privacy issues, RFC's, software forensics, security guidelines and policies, trusted systems, and viruses.

Information on software which will break the encryption used in a large number of commercial software packages, including WordPerfect (versions 4.2-6.1, regular or enhanced encryption), Microsoft Word (versions 2.0-6.1), Microsoft Excel (all versions including the Macintosh one), Lotus 1-2-3 (all versions), Quattro Pro, Paradox, Pkzip, Norton's Diskreet (both DES and proprietary encryption), Novell NetWare (versions 3.x-4.x), and others, is available from the AccessData home page.

Another encryption-breaking package is available from the CRAK Software home page.

A number of other references to information pertaining to SFS are given at the end of the SFS documentation.
