Verify a Sealed Document

Upload a PDF to check if it has been sealed and verify its authenticity

How Verification Works

  1. Step 1: Upload PDF

    Drop or select the PDF file you want to verify.

  2. Step 2: Hash Computed

    We compute a SHA-256 hash of the file contents.

  3. Step 3: Match Found

    If the hash matches a sealed document, it's verified authentic.
