L0phtCrack 1.5 is a tool for turning Microsoft LANMAN and NT password hashes back into the original clear text passwords. The program does this using dictionary cracking and also brute force. L0phtCrack returns not just the LANMAN password but the NT password up to 14 characters in length. L0phtCrack includes the ability to dictionary attack or brute force the network NT server challenge that is used to prevent the OWF (one-way format) from going across the wire in its plain-text format. Sample network sniffed challenges are in files sniff.txt and sniff2.txt. This means you can obtain NT passwords without administrator privileges when you have network access between the client and the server.

After examining Tripwire and deciding that it was *way* overkill for my own purposes... ...L5 simply walks down Unix or DOS filesystems, sort of like "ls -R" or "find" would, generating listings of anything it finds there. It tells you everything it can about a file's status, and adds on an MD5 hash of it. Its output is rather "numeric", but it is a very simple format and is designed to be post-treated by scripts that call L5... ...Unlike Tripwire itself, this is NOT a complete toolkit -- one is expected to use it as a small, reliable part of a larger system... _H* Andrew McNaughton <andrew@scoop.co.nz>

Deadlock is an open source user authentication/password protection system written in PHP/MySQL and licensed under the GNU GPL. It uses .htpasswd and .htaccess files to protect any web directory.

libGringotts is a small, easy-to-use, thread-safe C library originally developed for Gringotts; its purpose is to encapsulate data (generic: ASCII, but also binary data) in an encrypted and compressed structure, to be written in a file or used elseway. It makes use of strong encryption algorithms, to ensure the data are as safe as possible, and allow the user to have the complete control over all the algorithms used in the process. For encryptions, libGringotts makes use of the MCrypt and MHash libs by Nikos Mavroyanopoulos.

COPYRIGHT ISSUES: This version of 'libident' is hereby released into the Public Domain. It may be distributed for a fee or without a fee. We only ask you not to pretend you wrote it. If you make any changes, please send sources or a diff of it to us (pen@lysator.liu.se or pell@lysator.liu.se), so we can keep _one_ unified version of libident available... COMMENTS: This is the second stab at a small library to interface to the Ident protocol server. Maybe this will work correctly on some machines.. :-) The ident-tester.c file is a small daemon (to be started from Inetd) that does an ident lookup on you if you telnet into it. Can be used to verify that your Ident server is working correctly. I'm currently running this "ident-tester" on port 114 at lysator.liu.se (130.236.254.1) if you wish to test your server.

Prelude is a Universal "Security Information & Event Management" (SIEM) system. Prelude collects, normalizes, sorts, aggregates, correlates and reports all security-related events. As well as being capable of recovering any type of log (system logs, syslog, flat files, etc.), Prelude benefits from a native support with a number of systems dedicated to enriching information even further (snort, samhain, ossec, auditd, etc.). This library provides a framework for easy access to the Prelude database.

Although the creator of scrypt has written an "example implementation", it doesn't satisfy the "simple library" requirement that prompts developers to implement it. Therefore, I've written my adaptation, which quite simply pulls the relevant parts from the original implementation, then adds a number of harnesses and simplified interfaces. The hope is that through this, any developer can utilise scrypt.

libgnomesu is a library for providing superuser privileges to GNOME applications. It supports consolehelper, PAM and su. libgnomesu will use one the following services (in order of priority), depending on which one is available: - consolehelper - PAM - su libgnomesu will use the su-based backend as final fallback, if no other services are available. This service uses a backend which is a modified version of GNU su. libgnomesu comes with the GUI frontend 'gnomesu' and a Nautilus component for Nautilus integration.

LibTomCrypt is a portable ANSI C cryptographic library that supports symmetric ciphers, one-way hashes, pseudo-random number generators, public key cryptography (via RSA,DH or ECC/DH) and a plethora of support routines.
