Keychain Framework is an Objective C Foundation-based framework for accessing Keychain and Security services under MacOS X. It provides convenience wrappers around the CDSA library included with MacOS X, facilities for manipulating keychains, and more.

Encryption with symmetric-key algorithm Kirmah - generate keys with exotic chars - redefine key length - key mark to ensure decryption capabilities - mix data - fast with multiprocessing - possible compression - gui on gtk3 - cli tool - python3 DEPENDENCIES : ======== python3, python-gobject, gobject-introspection, pygtk 3 modes are available to encrypt : ======== - compression (full / disabled or only final step) - random (simulate a random order - based on crypted key - to randomize data) - mix (mix data according to a generated map - based on crypted key - with addition of noise) Process is as follow : ======== encrypt : file > [ compress > ] encrypt > [randomiz data > mix data > compress > ] file.kmh decrypt: file.kmh > [ uncompress > unmix data > unrandomiz data] > decrypt > [uncompress > ] file ======== for encrypt/decrypt large binary files, use the fastest alternative : split/merge

The Latin Square Toolbox contains software tools for efficiently generating Latin squares and counting their transversals with various user-configurable options. This open source release aims to help educate folks on Latin squares and their important applications to cryptography. This version contains three tools: 0. Latin Square Generator (LSG) 1. Latin Square Transversal Counter (LSTC) 2. Latin Square Property Checker (LSPC)

LockPhix provides a solid base to build a full encryption suite. LockPhix consists of three tools: FileVault an en-/decryption tool, ScreenLock a way to lock your PC and PasswordSafe a tool to safely store passwords.

Blinded digital cash mint, walletware, tools, and open protocols.

Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit Windows - MLCrypt was created because of this. The program's primary aim is cascade encryption: create an encrypted outer layer over an existing compressed and encrypted archive file. (Each encryption layer should have a different complex password.) MLCrypt.zip contains all the executables: Linux, Windows, Raspberry Pi.

Multiprecision unsigned number template library (MUNTL). The program is intended for the organization of calculations with the big precision for unsigned numbers. Program is very fast because do not use any heap call (new, malloc etc.)

I'm using an MD5 hash of a username and password field to generate some entropy which is used to generate color pallets and positions / scaling of two Mandelbrot sets. These two images are overlaid to create interesting pictures which represent the entered credentials. I'm interested in all things security, this is mostly just for fun, but could possibly be used to help users identify mistakes in their password entry prior to submission and enforce a tighter failed password lockout policy. Please enjoy with a modern HTML5 enabled browser.

MathX is a fixed-length arithmetic-types written in pure c++ templates. The goal is to provide signed-integer, unsigned-integer, IEEE-754 float-point and fixed-point types, all with specific number of bits. To this moment, only signed-integer and unsigned-integer are completed for little-endain architecture. Any compiler that support c++03 or c++11 can successfully compile MathX. Refer to README for more information.

The Mav.Crypt tool will be upgraded to many different encryption methods. At the Moment, the only method is ROT13, but we are developing some other technics and a new Algorithm. More Infos shortly at the Project Web Page.

Md5 Project es un programa que encripta una cadena de caracteres y la mete en una base de datos, para posteriormente desencriptar el hash creado. Para ver el programa en funcionamiento: http://md5-project.razican.com/ Está traducido a tres idioma

Messa is a fully distributed instant messaging and presence application.

MetFS is a filesystem in userspace that is FUSE based, encrypted, dynamic sized (increase when new data added, decrease when data removed), single file when it's unmounted and very fast. MetFS 's proved to be running on Linux and FreeBSD.

a small library for cryptography (e.g. for the MicroEdition of Java) that supports AES (256 bit only), SHA-512 and CBC. The library is available in Java and JavaScript.

This repository contains the standalone desktop application from the Midbar project. The app operates entirely offline and does not require an internet connection. GitHub repository: https://github.com/Northstrix/Midbar-Desktop-App

MikroLock is a fast native implementation of the open minilock file format (https://minilock.io). Despite its name (and in contrast to the original implementation), it can also handle BIG files.

The Moonbounce API is a set of high level objects that encapsulate pieces of the Bouncycastle lightweight crypto API. Moonbounce significantly simplifies RSA key generation, signing, encryption/decryption and verification of both byte arrays and files.

Rsync friendly encryption that runs on the UNIX command line. Encrypt a file and backup the changes to an untrusted host.

Net.MD5 is a handy MD5 checker and generator. It can encode unlimited bytes of data into 32bit key, and auto compare against original key. A visual GUI will keep MD5 more friendlier. It was written in C# under .NET Framework 2.0

NimpSmartCard is a framework to interact with smart cards through PC/SC readers as well as test/production readers such as Micropross and Smartware. The framework comes with sample tasks and a sample terminal manager which supports scripts and logs

Onscreen passphrase entry tool for the truly paranoid! Enter pass phrases for encryption without touching your keyboard. Includes automatic hashing functions alongside ASCII-styled digests. This utility even randomly shuffles the positions of keys. Passwords can be up to 6000 characters long. (Windows 64bit OS only)

ObscureEncrypt is a high level security encrypter. It encrypts at three levels, 448 bit Blowfish encryption, Obscurity, high level encryption. Making it almost impossible to decrypt

A crossplatform key manager for GnuPG.

Off-the-Record (OTR) Messaging allows you to have private conversations over instant messaging by providing encryption, authentication, deniability, and perfect forward secrecy.

Security for usb flash drives. Uses basic encryption to make sure your data is safe, on all platforms. This application is written in C++, GUI is still to be considered. PRE-ALPHA STAGE, DO NOT USE ON IMPORTANT DATA!
