Open Source Assembly Security Software

VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

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.

Advanced Onion Router is a portable client for the OR network and is intended to be an improved alternative for Tor+Vidalia+Privoxy bundle for Windows users. Some of the improvements include UNICODE paths, support for HTTP and HTTPS proxy protocols on the same Socks4/Socks5 port with HTTP header filtering that generates fake identity-dependent headers every time the identity is changed (proxy chains are also supported), support for NTLM proxies, a User Interface that makes Tor's options and actions more accessible, local banlist for forbidden addresses, private identity isolation, a point-and-click process interceptor that can redirect connections from programs that don't support proxies, also giving them fake information about the local system and support for .onion addresses. Also, it can estimate AS paths for all circuits and prevent AS path intersections, it can restrict circuits to be built using only nodes from different countries, can change circuit lengths and more.

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.

The most complete and Advanced Penetration Testing and Ethical Hacking Platform dedicated to Advanced Professionals. Developed to bring the power of Offensive Security in the anyone's pocket 100% OPEN SOURCE - ANDRAX is a independent solution for Security professionals who loves Linux

DiskCryptor - fully open solution to encrypt all partitions, including system. The program is a replacement for proprietary DriveCrypt Plus pack and PGP WDE.

Swift Crypto is a cross-platform, open-source implementation that mirrors a substantial portion of CryptoKit so server and Linux/Windows ARM64 apps can share one modern crypto API. It exposes high-level, misuse-resistant primitives with Swift ergonomics while delegating to well-vetted backends under the hood. The repository maintains active releases and issue tracking for enhancements like PEM handling and ecosystem compatibility. High-level, misuse-resistant primitives and key handling. SwiftPM distribution for easy inclusion in builds. By matching CryptoKit’s surface, it reduces portability friction between Apple platforms and server environments. The package slots cleanly into SwiftPM builds and is widely adopted across the Swift server ecosystem. Its goal is practical cryptography: safe defaults, clear APIs, and predictable performance.

BitVisor is a tiny hypervisor initially designed for mediating I/O access from a single guest OS. Its implementation is mature enough to run Windows and Linux, and can be used as a generic platform for various research and development projects.

See http://silcnet.org/ for detailed information. SILC provides common chat and conferencing services like private messages, instant messages, channels and groups, and video and audio conferencing. The main difference to other protocols is that SILC has been designed with security as its main feature. All packets and messages sent in SILC network are always encrypted. Private messages are encrypted end-to-end, channel message are encrypted with channel-wide secret key and secure file transfer is protected peer-to-peer.

Based on MATE environment HackShark Linux is a lightweight distribution for penetration testing, cyber forensic investigation and vulnerability assessment purpose.

Unicornscan is an asynchronous TCP and UDP port scanner developed by the late Jack C. Louis.

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".

Yoda's Protector is a free, open source, Windows 32-bit software protector.

Libecc is an Elliptic Curve Cryptography C++ library for fixed size keys in order to achieve a maximum speed. The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves.

This is an implementation of elliptic curve cryptography using the Montgomery and Edwards curves Curve25519, Ed25519, Ed448-Goldilocks and Curve448, using the Decaf / Ristretto encoding.

This project aims to pool together as many kernel projects as possible, ironing out conflicts where possible, so that experimental kernel projects can get greater exposure, safely, and so that those projects can be tested under much more varied conditions

AVR128DA /Atmega128 microcontroller based open source EID smartcard with RSA (512-2048) and ECC (prime192v1, prime256v1, secp384r1, secp521r1 and secp256k1) support. Compatible with MyEID card from Aventra. Supported in windows and linux by opensc package. Allow about 64KiB space for keys/certificates. PKCS#15 structure supported. USB token with CCID interface based on xmega128a4u with same features as card. High speed AVR multiple precision arithmetic: squaring, multiplication, exponentiation.

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.

RemCom is RAT [Remote Administration Tool] that lets you execute processes on remote windows systems, copy files, process there output and stream it back. It allows execution of remote shell commands directly with full interactive console.

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.

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).

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.
