Kerberos: The Network Authentication Protocol
|
Recent News
21 May 2020 — krb5-1.18.2 is released
The krb5-1.18.2 source release is now available.
11 Dec 2019 — krb5-1.17.1 is released
The krb5-1.17.1 source release is now available.
Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. A free implementation of this protocol is available from the Massachusetts Institute of Technology. Kerberos is available in many commercial products as well.
The Internet is an insecure place. Many of the protocols used in the Internet do not provide any security. Tools to «sniff» passwords off of the network are in common use by malicious hackers. Thus, applications which send an unencrypted password over the network are extremely vulnerable. Worse yet, other client/server applications rely on the client program to be «honest» about the identity of the user who is using it. Other applications rely on the client to restrict its activities to those which it is allowed to do, with no other enforcement by the server.
Some sites attempt to use firewalls to solve their network security problems. Unfortunately, firewalls assume that «the bad guys» are on the outside, which is often a very bad assumption. Most of the really damaging incidents of computer crime are carried out by insiders. Firewalls also have a significant disadvantage in that they restrict how your users can use the Internet. (After all, firewalls are simply a less extreme example of the dictum that there is nothing more secure than a computer which is not connected to the network — and powered off!) In many places, these restrictions are simply unrealistic and unacceptable.
Kerberos was created by MIT as a solution to these network security problems . The Kerberos protocol uses strong cryptography so that a client can prove its identity to a server (and vice versa) across an insecure network connection. After a client and server has used Kerberos to prove their identity, they can also encrypt all of their communications to assure privacy and data integrity as they go about their business.
Kerberos is freely available from MIT, under copyright permissions very similar those used for the BSD operating system and the X Window System. MIT provides Kerberos in source form so that anyone who wishes to use it may look over the code for themselves and assure themselves that the code is trustworthy. In addition, for those who prefer to rely on a professionally supported product, Kerberos is available as a product from many different vendors.
In summary, Kerberos is a solution to your network security problems. It provides the tools of authentication and strong cryptography over the network to help you secure your information systems across your entire enterprise. We hope you find Kerberos as useful as it has been to us. At MIT, Kerberos has been invaluable to our Information/Technology architecture.

Updates for 2007 US Daylight Saving Time rule changes:
If you are running KfW on a system where the TZ environment variable is set, you will need an updated .NET 2003 C Runtime Library (included with the new kfw-3.1.1 installers) in order to get correct DST behavior. Having a TZ environment variable setting is a somewhat uncommon configuration primarily used for compatibility with older applications; if the TZ environment variable is not set, KfW correctly obeys the DST rules set in the operating system.

The MIT distribution for Microsoft Operating Systems has been significantly revised. This release contains a new packaging model for Kerberos V4 and V5. The Release 2.0 for Microsoft Operating Systems integrates some of MIT’s earlier work with Kerberos V4 and the Kerberos V5 1.1 release. It includes the source code for Leash32.exe, krbcc32.dll, kclnt32.dll, krbv4w32.dll, fleavius.exe, leashw32.dll, vs32.dll, and wshelp32.dll, in addition to the Version 5 1.1 sources.
Developers that only desire the Kerberos Version 5 1.1 sources can build the code from the krb5-1.1.tar file.
Building the Win32 Kerberos sources from the tar file will require a UNIX machine for part of the process. The UNIX machine will be used to create the platform specific make files, and a zip file. The zip file will then be expanded on the Windows machine and the sources can be compiled. This method only requires the compiler on the Windows machine.
Building from the kerberos-win32-2.0.zip files does not requires the use of a UNIX machine. However, it does require MSVC++ 6.0, ActiveState Perl build 517, sed, gawk, cat, and rm in your path. More information about these can be found in the release notes that are contained in the zip file.
There are currently two packages for release 2.0 available: binaries, and source. We are still working on creating an SDK package. The source code is for people who need to debug Kerberos or want to build the libraries from scratch. The binary distribtion contians an installer, however other sites may still need to localize their distribution.
The files may be extracted from the installer, without performing the normal installation. The /X command line option allows you to extract single files from the installation executable. The files that are contained in the Wise executable will be listed along with the file dates and sizes.You can then select a file and choose the directory to place the file into. If you follow the /X option with a pathname, all of the files in the installation executable will be placed into that directory. If the directory does not exist, it will be created. The /Z command line option acts exactly like to /X option except Windows will be exited after the files are extracted. This can be useful for administrators that want to perform virus scanning on all of the files in the Wise executable.

Mac OS X 10.2 and later bundles MIT Kerberos for Macintosh. To get the latest version of MIT Kerberos for Macintosh, please upgrade to the latest version of Mac OS X available from Apple. To download the Kerberos Extras for Mac OS X 10.2 and later to enable Kerberos support for CFM applications, please read this page.
Kerberos for Macintosh 4.0.3 is the current release for Mac OS X 10.1.x.
Kerberos for Macintosh 4.0.3 is the current release for Mac OS 8/9.
There is currently only one package available which includes both installers, loose binaries and SDKs. The SDKs are for application and library programmers to add Kerberos functionality to their code or update to newer versions of the various Kerberos APIs. Source code for components of this release may be made available at a later time.
Further links to information are provided in the distribution archive.
Note for MIT users
If you are an end user at MIT and are on this page to acquire the Kerberos for Macintosh binaries, you should go to the Information Systems’ Kerberos for Macintosh help page for the software. No support will be provided to you from MIT Information Systems or the developers if you use the distribution from this page. MIT users should stay with the current release supported by IS.
Requirements
- Mac OS 8/9
- A PowerPC based Macintosh computer running Mac OS 8.1 to 9.2.2 or Mac OS X’s Classic environment.
- Carbon libraries require CarbonLib 1.0.4 or later.

Binaries and SDKs
- MIT Kerberos for Macintosh 4.0.3 ( Macbinary III self mounting disk image, 20.1MB, 10/2/2002)
This release continues the new packaging model of Kerberos V4 and V5 on the Macintosh. While integration of Kerberos V4 and Kerberos V5 is at best only partial at this time, we are putting the separate sides together under one umbrella to better prepare for the upcoming unified release.
Kerberos for Macintosh 2.5.1 includes: KClient 1.9 for Kerberos V4 functionality, and the various pieces that make up Kerberos V5 1.1 for Macintosh.
There are currently three levels of packages: binaries only, SDKs, and source. The binary distribution is for sites who need to localize and redistribute to their end users. The SDKs are for application and library programmers to add Kerberos functionality to their code but don’t want to rebuild everything from scratch. The source is for people who need to debug Kerberos or want to build the libraries from scratch.
Note for MIT users

CNS is the Cygnus Network Security release of Kerberos version 4. It is based on years of continued development starting from earlier MIT V4 releases. The last release available from Cygnus was 96q1; 96q4 has one minor security fix over 96q1. A further release with a number of portability enhancements is planned.
CNS is a available as a compressed tar file (approximately 1600k).
