How to use it

  1. Choose a file (or switch to Text) and the algorithms you need.
  2. Wait a moment. Hashes appear as soon as they are calculated.
  3. Paste the published checksum to see whether it matches.

Examples

  • SHA-256 of an empty input: e3b0c442…b855
  • MD5 of abc: 900150983cd24fb0d6963f7d28e17f72

Use SHA-256 or stronger to verify downloads. MD5 and SHA-1 are fine for spotting accidental corruption but are not secure against deliberate tampering. A hash identifies file contents, not its name or date. Files up to 1 GB are supported.
