Stop Cyber Threats with VM-Series Next-Gen Firewall on Azure
Native application identity and user-based security for your Azure cloud
Gain integrated visibility across all traffic in a single pass. Deploy Palo Alto Networks VM-Series to determine application identity and content while automating security policy updates via rich APIs.
Note: I haven't even looked at this project for years. I was a pretty bad programmer back then, so the code is sloppy. The next version will be better.
Similar to a stream cipher, but rather than performing an exclusive OR on the input bytes and cipher, it performs a mixture of 'rolling' (see x86 instruction ROR) and bit NOT operations according to the key.
mcrypt, and the accompanying libmcrypt, are intended to be replacements for the old Unix crypt, except that they are under the GPL and support an ever-wider range of algorithms and modes.
Code to brute force the 32-bit key used to RC4 encrypt .pwl files.
PROJECT HAS MOVED TO GITHUB:

This is the repository of my (PP) personal tools, scripts, programs, specifications and writings. I'm giving most of my smaller work to the world to use it, for free.
Black scalpel is an advanced graphical (Swing gui) security and analysis tool written in Java, C and Assembler (platform independent). Current stage is early alpha, many features are still missing. Use SVN!
Derived from TrueCrypt 6.3 release, I added some command line options to "TrueCrypt Format.exe" to allow TrueCrypt volumes to be created without using the graphical user interface
A hardware supported hypervisor originally built for malware analysis. Features: Linux VM introspection, minimal detectability, small (~150KB), simple, and well documented. Can be used for other purposes. Support for Intel-VT & Windows coming soon.
BeeCrypt is an ongoing project to provide a strong and fast cryptography toolkit. Includes entropy sources, random generators, block ciphers, hash functions, message authentication codes, multiprecision integer routines, and public key primitives.
Innovative prototype of network applications such as TCP fuzzers that can be used for many purposes such as network and application security assessments and more. Adapt it freely to fit your needs or to simply understand how TCP works in .NET.
DiskCryptor - fully open solution to encrypt all partitions, including system. The program is a replacement for proprietary DriveCrypt Plus pack and PGP WDE.
This project is intended to demonstrate that current popular approaches to software security (e.g. DAC, VMA randomization, etc) are not sufficient and that other approaches should be considered more seriously (e.g. MAC, design by contract).
Open source antivirus developed in C++. Detects and eliminates viruses, trojans, worms, adware, spyware, rootkits, also protects against phising attempts and network attacks.
GTCop Professional Security Appliance aims to provide a powerful tool for satellite communications, with enhanced QoS and bandwidth controls. As derived from IPCop Firewall, it is a stable, secure, easy to configure and maintain GNU/Linux firewall box.
File Crypter is a Simple program, that is able to encrypt your files and decrypt them. A version of File Crypter is included as an example in the xCrypter Library and is called "ncrypter" which is short for "new crypter".
Strokey is a small hardware keyboard logger saving all keystrokes into an EEPROM memory for later investigation. The device may get attached to any PS/2-keyboard by intercepting the cable, or get placed directly inside for maximum invisibility.
This project aims to develop a prototype system that explores how we should re-invision computer system design based on changes in how people get the software that they run, as well as advances in static analysis of software.
A package of Rijndael, Twofish and Serpent encryption algorithms implemented in x86 assembly. Meant to learn basics of assembly, learn about the algorithms or to be used in a C program.
Cnc's IP Data Volume Report:
Logs IP to IP contact, number of packets, bytes, time of contact, Ethernet too!
View via local web interface.
Very simple for those who want to view who your computer is contacting the most!
Software repository of the hack://src project. Includes security related software for crypto, vulnerability/patch notification & management, and ultra low level system access for stealth forensics & intrusion detection or malware removal.
The Nexus Operating System is a planned, realtime multimedia operating system compliant with POSIX standards. Nexus is intended not to become the next fad; it is the OS all developers can develop for without losing market standing in other OS's.
Powerful 512bit pseudo random encryption, optimized for the x86-64 architecture. Coded in x86-64 assembly language, this has the potential to be one of the most powerful and fastest file encryption engines to date.
This is the worlds first and probably only FLOSS project aimed to create a lowbudget, based on availble technology, cruise missile. No this is not a Joke, its for real. Why? Since no one has tried to do this before and certainly not under the GPL.
