Zoom The user interface hasn't changed much over the past few years.
While "Duke Nukem Forever" will now never appear, the legendary L0phtcrack password cracker is returning and in the form of a new version 6 too. L0phtCrack disappeared from the market after @stake, a company which was formed by L0pht Heavy Industries and others, was taken over by Symantec. At the beginning of this year the original L0phtCrack team, consisting of Christien Rioux, Chris Wysopal and Peiter Zatkhat (Mudge), bought back the software rights from Symantec and have now upgraded the tool.

Version 6 is now able to run on 64-bit versions of Windows and supports multiprocessor systems as well as pre-computed hash tables (rainbow tables) for cracking, or rather "testing the strength of", Windows and UNIX passwords. Testing can be done automatically at regular intervals, both locally and via the network, generating a report that summarises the results in graphical form.

Not much else has changed; A wizard continues to assist with preparing various tests. The user interface has been given a bit of a makeover, but all the elements are still in their usual places.

A 14-day trial version is available to download. However, according to the developers, L0phtCrack is subject to US export restrictions and is only available to users in the United States. The free Cain & Abel or John the Ripper password crackers can be used as an alternative to L0phtCrack.
