Your privacy matters
All files are processed locally in your browser. Nothing is uploaded to our servers, so your documents remain private and secure.
Common use cases
- Verifying a downloaded file against a published SHA-256 checksum
- Generating cache keys or content fingerprints during development
- Comparing two files quickly by their digests
- Producing MD5 sums for legacy systems that still require them
- Hashing strings while debugging webhook signatures
Why Hash Generator?
Hashing on a website usually means pasting your content into someone else's server. Here the SHA family runs on the browser's built-in Web Crypto API and MD5 runs as local JavaScript — the bytes never leave your device, which matters when the thing you're checksumming is a private build artifact or licensed download.
Hash Generator keeps the job narrow: checksum a file or hash a string without it ever leaving your machine. It is built for the small but frequent moments when opening a heavyweight editor, installing a package, or uploading sensitive work to a random service is more friction than the task deserves.
