Open Source Cryptography Software

This project provides a simple Java-based steganography tool that can hide a message inside a 24-bit colour image so that knowing how it was embedded, or performing statistical analysis, does not make it any easier to find the concealed information.

mp3stegz is an application that apply steganographic (steganography) algorithm in mp3 files. mp3stegz will maintain original mp3 file's size and sound quality. The hidden message is compressed(zlib) and encrypted(Rijndael).

Hide In Picture is a program that allows you to conceal files inside bitmap pictures, using a password. The pictures look like normal images, so people will not suspect there is hidden data in them.

Simple way to encode files and images in base64... Tutorial: http://www.youtube.com/watch?v=G1cQXnzOwcs

Steganography program. Crypture encrypts (1024 bit key) and stores files in Windows bitmap files. Only 6 KB, with no install required. Fills all bits with noise, to slip by standard steganalysis methods. Data header is encrypted and scattered as well.

Composed of a Java steganographic library and GUI to use steganography. Primarily intended for research communities on security and steganography to implement new dissimulation and steganalysis algorithms. More information at www.hidereveal.org

This project is a Steganography software that allows you conceal files inside any picture type.

The goal of this project is to design and write comercial quality software and aplications with fully respect to free software (like in "free speach"). The software designed by us will target various fields: from scientific applications to multimedia an

2Pix integrates with Windows to allow you to easily encrypt and hide files in bitmap images, a process called steganography (not to be confused with stenography). Data is stored in the low-order bits of each pixel of an image, so the file is completely hidden from view. Version 1.1 now provides plausible deniability because no unencrypted signature is stored in the image header. It should be impossible to prove an image contains a hidden file (if you use a strong password and only use 1 or 2 bits per pixel component). NOTE: This project has been moved to Google Code. http://code.google.com/p/2pix-steganography

BMPE stands for Bitmap Editor and is an cross platform open source application written in java for editing and extracting messages from BMP files.

BinaryPix is a Tool to create "Binary-Visual" Code out of ASCII-Text Then it places it on a choosen picture. Then you are able to water-mark your pictures with the "binary-hidden" code.

Ce logiciel d'optimisation va vous permettre d’effectuer de nombreuses tâches informatiques régulières en toute simplicité !

A simple app that enables you to sign the files and verify their integrity/authenticity using the ECDSA and SHA-512. I originally developed this app for my university course, but I also decided to post it on GitHub on Sourceforge. This application is made for educational purposes only. Despite having well-functioning cryptographic features, it may not be reliable. This application is provided with no warranty or guarantees of any kind. Use it at your own risk! Made with the help of the ChatGPT and Perplexity. GitHub page: https://github.com/Northstrix/ECDSA-File-Signer

Stegonography project developed for ITS 450 - Software Assurance under the instruction of Prof. Sydney Liles.

Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography comes from New Latin steganographia, which combines the Greek words steganós , meaning "covered or concealed", and -graphia meaning "writing".

The purpose of this project is to provide a biometric security solution by using voice print, fingerprint and/or facial recognition along with a password and/or smart card support using AES to protect data. Please read forums for if interested.

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.

A Win32 API based graphical desktop sharing system, it support LZMA compress, MD5 password check, 64bits file transfer, 8bits instruction fast protocol and windows's pack intelligence for reduce useless transfer band.

ScatterStorm Mosaic Image Encryptor is not your father's stegonagraphy engine. It's purpose is not to sneak data around in image trojan-horses as much as to be able to reversibly scramble an image (or parts of one) in a mosaic cloud

Seagull is a peer to peer network client software that allows user to communicate and share files over secure connections and secure peer to peer identification and handshaking.

With this software, you can embed the text message into a graphic file. The result file looks exactly the same with the original. But if you use this software, you can see the hidden text inside the pciture

Snarfzilla was a GUI and web browser for the official Freenet Java server. The first web browser for the dark web. It hasn't been compatible with Freenet for several years and development ceased.

Projeto de software parte integrante do trabalho de conclusão de curso de Tetri Mesquita Neto, do curso de Bacharelado em Informática, na Universidade Estadual do Oeste do Paraná - UNIOESTE, campus Cascavel-PR.

Utility for embedding hidden data into PNG files

This is a PHP library that can be used to hide data (messages or files) in images using steganography techniques. The data in the image only exists symbolically and thus only you and the intended recipient will know of the existence of that hidden data.
