How to use the Hash Generator

  1. 1

    Every hash at once

    MD5, SHA family, SHA-3 and CRC32.

  3. 3

    Compare a checksum

    Paste the expected value to verify a match.

Check a download against its published checksum, or hash a value for a database or API. All hashes are computed at once, files of any size are streamed, and nothing leaves your browser.
