Verifying file integrity is essential to ensure that files haven’t been tampered with or corrupted during the transfer.</p> <p>While there are existing tools, many are:</p> <ul> <li>Tied to a specific OS 🖥️</li> <li>Heavy or overly complicated 🧱</li> <li>Not open source ❌</li> </ul> <p>Hash Checker was created to offer:</p> <ul> <li>✅ Cross-platform support (Windows, macOS, Linux)</li> <li>✅ Simple and fast verification</li> <li>✅ Lightweight, minimal dependencies</li> <li>✅ Open source for transparency and contribution</li> </ul> <p>⸻</p> <h2> 🧰 How to use </h2> <ul> <li>Download the latest release </li> </ul> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>https://github.com/tamld/hash-checker/releases </code></pre> </div> <ul> <li>Run the app and select your file.</li> <li>Choose a hash algorithm (e.g., SHA-256).</li> <li>Compare the computed hash with the expected value.</li> </ul> <p>⸻</p> <h2> 🖼️ GUI Preview </h2> <h3> 1.
