    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.

    2Pix
    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

    ECDSA File Signer

    ECDSA File Signer

    A simple app that enables you to sign the files using ECDSA and SHA512

    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

    MandelHash

    MandelHash

    MD5 hash used to position and color two overlaid Mandelbrot sets.

    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.
