[FEATURED GUIDES]
What is File Hashing?
A beginner-friendly introduction to hash functions. Learn how cryptographic hashes work, why they're called "digital fingerprints," and why they matter for security and file verification.
How to Verify Downloaded Files
A step-by-step practical guide to verifying file integrity. Learn where to find official checksums, how to calculate and compare hashes, and what to do when verification fails.
Choosing the Right Hash Algorithm
Detailed comparison of MD5, SHA-1, SHA-256, SHA-512, and BLAKE2b. Understand security levels, performance characteristics, and get clear recommendations for every use case.
[QUICK REFERENCE]
Need a quick answer? Here are the most common questions:
- › Which algorithm should I use? SHA-256 for most purposes. See our algorithm guide for details.
- › Are my files uploaded? No. All processing happens in your browser. Learn more.
- › What if hashes don't match? Check algorithm, file version, and try re-downloading. See our verification guide.
- › Is MD5 safe? Not for security, but fine for detecting accidental corruption. Details here.
