Open Source Windows 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.

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.

Utility for embedding hidden data into PNG files

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

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.
