Hashed locally · SHA family via Web Crypto, MD5 via js-md5 · Verify checks all algorithms, even the one you’re not viewing.

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes of text or files, compute HMACs with a secret key, and verify a checksum by pasting it in. Everything is computed on your device.

How to use Hash Generator

  1. 1Choose Text or File as the source.
  2. 2Pick an algorithm (SHA-256 by default).
  3. 3Optionally enable HMAC and enter a secret key.
  4. 4Copy the digest, or paste a checksum into Verify to confirm it matches.

Frequently asked questions

Yes. Switch to File mode and drop in any file — it’s hashed entirely on your device, so even large files never upload.
Hash the file, then paste the published checksum into the Verify box. The tool checks it against every algorithm and tells you which one matches — handy when you’re not sure if it’s MD5, SHA-1, or SHA-256.
HMAC uses the browser’s Web Crypto, which supports the SHA family but not MD5. MD5 is still available for plain hashing.
No. Everything runs entirely inside your browser using your own device — your files never leave your computer or get uploaded anywhere. That makes it private and fast, even for large files.
Yes, completely free with no sign-up, no watermark, and no daily limits. Use it as much as you like.
