Signing differs by platform, and each download card above names how its file is signed.
The app updater checks Minisign signatures on update bundles. That check is separate from macOS notarization, Windows publisher identity, and Linux GPG signatures.
Linux verification requires the matching .asc file and a publisher key whose fingerprint you have confirmed through a trusted channel. The signature file alone does not verify the download.
