Ophcrack 3.4.0 full description

What is ophcrack?

Ophcrack is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms.

Features:

* » Runs on Windows, Linux/Unix, Mac OS X, ...
* » Cracks LM and NTLM hashes.
* » Free tables available for Windows XP and Vista.
* » Brute-force module for simple passwords.
* » Audit mode and CSV export.
* » Real-time graphs to analyze the passwords.
* » LiveCD available to simplify the cracking.
* » Loads hashes from encrypted SAM recovered from a Windows partition, Vista included.
* » Free and open source software (GPL).

Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman's original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds.

Ophcrack 3.4.0 Windows 7 release notes

New Release
This new LiveCD includes the latest version of ophcrack 3.4.0.

It is built on Slitaz 4.0, the latest version of this great LiveCD. Christophe Lincoln from Slitaz helped us to enhance the scripts for partitions and tables detection. A new ncurses interface is also available to help users look for tables on other drives or interact with ophcrack.

Finally a LiveCD without tables has been released as well for users that already downloaded or bought tables. The directory containing the table files must be placed inside another directory called tables in order for ophcrack to find them automatically.
