What a check tells you
Verified label
This content matches the version signed by a trusted signer.
Valid label, signer not confirmed
This content matches its signed version, but we could not verify who signed it.
Changed after signing
This content no longer matches the version that was signed.
No label found
This content has no label.
Verification unavailable
We could not check this content right now.
The checker reads the label carried inside the file, and it looks for a supported invisible mark.
You see who signed, when, and whether the work changed. If a site removed the label and the invisible mark still leads to it, the result says the label was recovered. Otherwise it says no label was found.
The check is free. You need no account. A valid label does not mean the content is true.
Create. Mark. Endure.
