How to verify a file with SHA-256

  1. Choose the downloaded file.
  2. Paste the checksum from the download page into Compare.
  3. A green tick means the file is intact.

Why verify downloads?

Software publishers list SHA-256 checksums so you can confirm a file was not corrupted or tampered with. If even one bit differs, the hash will not match.
