Verify a timestamp token
Check an RFC 3161 token on its own: the moment it seals, the fingerprint it seals, who issued it, and whether that issuer was a qualified trust service at the time.
Everything runs on your device. The token is never uploaded, and Sealway is not asked to vouch for it.
Leave it empty and the sealed fingerprint is read and shown, but compared with nothing: what a token should cover is a question only you can ask.
A token claiming qualified status is making a claim about itself. Only an authenticated European Trusted List answers that question, which is the check named below.
