Entropy Visualizer & Simulator – Interactive Entropy Heatmap for Randomness Testing

The Entropy Visualizer & Simulator is an advanced entropy modeling playground built entirely with HTML, CSS, and JavaScript. This tool allows cybersecurity professionals, IT admins, and students to interactively simulate and visualize entropy generation from various simulated and real input sources like noise, mouse movements, and keystrokes. 🔐

It features a heatmap-style entropy grid, real-time dynamic entropy graph, and keyboard/mouse input detectors—all running client-side with responsive layouts, a polished dark-mode UI, and entropy source switching.

Loaded with LocalStorage for state-saving and packed in a neat design, use this simulator for educational demonstrations, security entropy quality checks, or simply to visualize cryptographic randomness like never before.

My name is Skylar Pearce, I have been working as a System Administror since 2013 as well some side consulting work. During my career I have worked with everything from Active Directory and vCenter to configuring routers and switches and phone systems, documenting and scripting my way through the whole thing. I have a Security+ certification and am currently working on my PenTest+. Throughout my career I have gained almost all of my knowledge from blogs like this. It is now time for me to pay it back. Over time I have gathered scripts and tricks over the years that I will share on this site. A lot of the posts here will be mainly reference posts, some will be full on how to’s. I am happy to go into more depth on any other topics I go over here, just make a comment on a post. I will do my best to post once a day on weekdays but as I run out of ideas it may slow down. My WordPress skills are still growing so the site will likely get better over time as I learn. You can reach me at contact@allthesystems.com or on LinkedIn
