PassCore is a very simple 1-page web application written in C#, using ASP.NET Core, Material UI (React Components), and Microsoft Directory Services (Default provider). It allows users to change their Active Directory/LDAP password on their own, provided the user is not disabled. PassCore does not require any configuration, as it obtains the principal context from the current domain. I wrote this because a number of people have requested several features that the original version did not...

...The passphrase-generator defaults to only 3 words instead of the 4 suggested by XKCD, but uses a larger dictionary found in many unix like systems at /usr/share/dict/words. It also provides estimates for the entropy of the generated passphrases. The randomization is based on /dev/urandom and SHA1. See http://xkcd.com/936/ for an entertaining take on passwords vs. passphrases. See my post in stackoverflow for links to other solutions and discussions on passphrases vs passwords: http://stackoverflow.com/a/12646320/1148030

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. ...
