Verify downloads by comparing a file's SHA-256, SHA-384 or SHA-512 checksum with the publisher's value. Clear pass/fail result; the file never leaves your device.

Files are processed in your browser with the Web Crypto API and never uploaded. Very large files (over ~2 GB) may exceed browser memory; use the command line instead.

How to use it

  1. Download the file and find the expected checksum on the publisher’s official page.
  2. Choose the file above and select the algorithm the publisher used, usually SHA-256.
  3. Paste the expected value (spaces, 0x prefixes and letter case are ignored) and click Verify.

You’ll get a clear MATCH or NO MATCH. The comparison runs entirely in your browser.

If it says NO MATCH

Don’t run the file. Re-download it from the official source and check that you copied the right hash, since releases often list several files. If it still fails, the file may have been tampered with. Our checksum guide explains what to do next.

Why trust the result?

The hash is calculated with the browser’s native Web Crypto implementation, not custom JavaScript cryptography. This page is served with a strict Content Security Policy, so third-party scripts can’t run on it.
