A file hash (or checksum) is like a digital fingerprint. If even a single byte of a file changes, the hash changes completely.
Common Uses
- Security: Verify that a software installer (like an .exe or .dmg) hasn't been tampered with by hackers.
- Integrity: Ensure a large file transfer (like a video or zip) completed successfully without corruption.
- Privacy Note: This tool uses the Web Crypto API. Your file is processed in your browser's RAM and never transmitted over the internet.
