Verify a Signed File

Drop the .signed.zip you received (or the file + audit log separately). We'll tell you in 2 seconds whether it's authentic and unmodified. Works for any file type.

🔒 Verify it yourself: after this page loads, turn off your Wi-Fi and verify anyway. The whole check runs in your browser — we never see the file, the audit log, or the result.

Drop a .signed.zip, OR drop the signed file + .audit.json together. We accept either.
