Elcomsoft Distributed Password Recovery
Elcomsoft Distributed Password Recovery (EDPR) offers administrators a comprehensive solution for recovering passwords to Microsoft Office documents when employees forget or lost their passwords. EDPR lets you coordinate all of the unused computing power of every computer on your LAN or WAN, and use distributed processing to restore the lost password by installing the "agents" onto as many computers on the network as the user desires; each of these agents uses brute force to try to recover the lost password. EDPR restores passwords for Word and Excel documents encrypted with 40 bit keys (Office 97/2000 compatible) as well as more recent documents (Office XP/2003) encrypted with CSP. Office 97/2000 documents can be also decrypted by recovery of encryption keys instead of password, and that type of attack gives a guaranteed result regardless of password length and complexity.
Cryptanalysis tool that can be used to attack old ciphers. Additional can be used to analyse cookies. (Multi-threaded)
Advanced Archive Password Recovery
Advanced Archive Password Recovery is a program to recover lost or forgotten passwords for ZIP(PKZip/WinZip), ARJ/WinARJ, RAR/WinRAR and ACE/WinACE (1.x) archives. Supports the customizable "brute-force" attack, effectively optimized for speed (for traditional ZIP encryption, up to 15 million passwords per second on Pentium 4); dictionary-based attack, and very fast and effective known-plaintext attack. Supports strong WinZip encryption (AES). Multilangual interface is provided.
EverCrack - Open Source Cryptanalysis Engine
EverCrack is a cryptanalysis engine. The overall design goal is to systematically break down complex ciphers into their simplex components for cryptanalysis (by the kernel). The kernel consists of an algebraic design (comparison and reduction) for breaking uniliteral, monoalphabetic ciphers instantaneously. Currently, it can break a 500-word cipher in less than 500 miliseconds. EverCrack currently has multi-language support for the user interface and cracking encryption in other language dictionaries (English, German, French, Spanish, Italian, Swedish, Dutch, and Portuguese).
Proactive System Password Recovery
Proactive System Password Recovery is a program to recover all types of Windows passwords: logon password (when user is logged on and has Admin privileges), screensaver password, .NET Passport password, RAS and dial-up passwords, passwords to shared resources, SYSKEY startup password, passwords stored in cached credentials, Wireless (WEP and WPA-PSK) encryption keys etc. The program also shows all users and groups (with their properties), allows to run any programs in other user's context, show password history hashes, read password hashes from SAM and SYSTEM files, read Protected Storage records, decrypt Windows scripts, reveal passwords hidden under the asterisks, enable disabled controls, and run brute-force and dictionary attacks on PWL files (Windows 9x). Finally, it shows product IDs and CD keys for Windows, Microsoft Office and other Microsoft software installed.
CalcChecksum is a simple utility for calculating various checksums easily with a graphical user interface.
Kismet is an 802.11b network sniffer and network dissector. It is capable of sniffing using most wireless cards, automatic network IP block detection via UDP, ARP, and DHCP packets, Cisco equipment lists via Cisco Discovery Protocol, weak cryptographic packet logging, and Ethereal and tcpdump compatible packet dump files. It also includes the ability to plot detected networks and estimated network ranges on downloaded maps or user supplied image files.
Lepton's Crack is a generic password cracker. It is easily-customizable with a simple plugin system and allows system administrators to review the quality of the passwords being used on their systems. It can perform a dictionary-based (wordlist) attack as well as a brute force (incremental) password scan. It supports standard MD4 hash, standard MD5 hash, NT MD4/Unicode, and Lotus Domino HTTP password (R4) formats.
audio-entropyd reads sound from a stereo soundcard, takes the difference between the left and right channels and feeds the result (via a secure hash) to the /dev/random entropy pool. This can be useful for machines which require a lot of random data (e.g IPsec security gateways) to ensure that the kernel entropy pool does not deplete and /dev/random does not block.
