πŸ” Checksum Challenge: Can You Match the Right Hash?

Whether you’re installing software, verifying file integrity, or writing automation scripts, checksums and hashing algorithms are essential tools in the IT pro’s security toolkit. But how well do you really know your MD5 from your SHA256?

Introducing the Checksum Challenge β€” a fast-paced, fun mini-game that tests your ability to identify the correct hash outputs. In each round, you’ll be presented with a sample input string (like ‘hello’) and a list of possible hashes. Your task is simple: pick the one that matches the chosen hash algorithm. Choose wrong, and you’ll learn why. Choose right, and your score climbs. 🧠

This tool is perfect for:

  • Learning how different hashes look and behave
  • Understanding common formats like MD5 πŸ› οΈ, SHA1, and SHA256 βš™οΈ
  • Training your eye to detect spoofed or incorrect hashes πŸ”

Features include:

  • Dark mode πŸŒ™ / light mode β˜€οΈ toggle
  • Real-time scoring and feedback
  • Completely client-side β€” fast, free, and privacy-respecting

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
