    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.

    MyDiary1000

    MyDiary1000

    Its A Diary/TextEditor that encrypts your text data using images

    This is a diary that allows you to digitally write entries and view them. What makes this a masterpiece from its counterparts is how user data is created and abstracted. User data is protected and stored in PNG images, the image it self is not encrypted but the data inside the image is encrypted. If you open any one of the created PNG images, they look like blank images!. These "normal" looking images protect your information from prying eyes. The simplicity and elegance of my program stores your data(password and entry) locally and hidden from everyone.
