🔍 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 — 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 🛠️, SHA1, and SHA256 ⚙️
• Training your eye to detect spoofed or incorrect hashes 🔐

Features include:

• Dark mode 🌙 / light mode ☀️ toggle
• Real-time scoring and feedback
• Completely client-side — fast, free, and privacy-respecting
