SHA-256 Document Verifier

Drop any file to compute its SHA-256 fingerprint, then optionally paste a known hash to confirm the document is unchanged. Everything runs in your browser — your file is never uploaded.

How to verify a TamperCheck report

  1. Open your forensic report and copy the SHA-256 hash from the cover page.
  2. Paste it into the field below.
  3. Drop the original document file into the tool.
  4. A green confirmation means the file is byte-for-byte identical to what was analysed.

Paste the SHA-256 hash from your TamperCheck forensic report to verify this is the exact file that was analysed.
