SHA-512 Hash Generator

Generate a 512-bit SHA-512 hash — the widest digest in the SHA-2 family.

To generate a SHA-512 hash, paste your text above and the 512-bit digest is computed locally. SHA-512 is often faster than SHA-256 on 64-bit hardware because it operates on 64-bit words, and it offers a larger security margin.

Frequently asked questions

How do I verify a downloaded file?

Switch the input to "A file", select your download, and paste the checksum published by the source into the verify box. A match means the content is byte-identical to what they hashed; a mismatch means you should not run it.

Is my file uploaded to check it?

No. Files are read from disk and hashed in your browser, in chunks, so even very large files never leave your device.

How to use the sha-512 hash generator

  1. 1Choose the hash.
  2. 2Enter or paste your text to hash.
  3. 3Select your file — the file stays on your device and is never uploaded.
  4. 4Enter or paste your verify against (optional).
  5. 5Turn "Uppercase hex" on or off as needed.
  6. 6Press Run, then download the result when it is ready.
